电动车电池知识
电动车电池知识电动车电池百科名片铅酸蓄电池现在的电动车上绝大多数装的是铅酸蓄电池，因为铅酸蓄电池成本低，性价比高。
1860年，法国的普朗泰发明出用铅做电极的电池。
这种电池的独特之处是，当电池使用一段使电压下降时，可以给它通以反向电流，使电池电压回升。
因为这种电池能充电，可以反复使用，所以称它为“铅酸蓄电池”。

科帝蓄电池铅酸蓄电池目前市场上能够大量提供的是铅酸蓄电池，铅酸蓄电池已经有130年的历史了，可以说是使用最多的蓄电池。
它的性能可靠，生产工艺成熟，价格也较低。
目前已商品化的电动自行车的绝大多数是使用的密封式铅酸蓄电池，使用中不需要补充水分，免维护。
其主要化学反应是：PbO2+2H2SO4+Pb←充电、放电→ PhSO4+2H2O+PhSO4铅酸蓄电池充电时变成硫酸铅的阴阳两极的海绵状铅把固定在其中的硫酸成分释放到电解液中，分别变成海绵状铅和氧化铅，电解液中的硫酸浓度不断变大；反之放电时阳极中的氧化铅和阴极板上的海绵状铅与电解液中的硫酸发生反应变成硫酸铅，而电解液中的硫酸浓度不断降低。
当铅酸蓄电池充电不足时，阴阳两极板的硫酸铅不能完全转化变成海绵状铅和氧化铅，如果长期充电不足，则会造成硫酸铅结晶，使极板硫化，电池品质变劣；反之如果电池过度充电，阳极产生的氧气量大于阴极的吸附能力，使得蓄电池内压增大，导致气体外溢，电解液减少，还可能导致活性物质软化或脱落，电池寿命大大缩短。
铅酸蓄电池重量比能量为28-40 Wh/Kg，体积比能量64-72 Wh/I，太重、太大，而提供的电能较少，使用寿命较短，作为电动自行车的动力电源一般只能够使用一年左右，若是性能差或使用不当的只有二、三个月。
Ni-MH (镍氢)电池的原理演示文稿
什么是电池的额定容量？ 2.4 什么是电池的额定容量？
2.4.1 指在一定放电条件下，电池放电至截止电压 时放出的电量。 2.4.2 IEC标准规定镍氢电池在20+ 5C环境下，以 0.1C充电16小时后以0.2C放电至1.0V时所放出的电 量为电池的额定容量，以C5表示， 2.4.3 比容量是指单位体积或重量的电池所给出的 容量，称之为重量比容量或体积比容量。 计算公式：C” = C/G(Ah.kg1)(读“安时每公斤)或 C”= C/V(Ah.L1)(读”安时每升)
2.8 什么是放电平台？
镍氢充电电池的放电平台通常是指电池 在一定的放电制度下放电时，电池的工 作电压比较平衡的电压范围，其数值与 放电电流有关，电流越大，其数值就越 低。
2.9什么是电池的标准充放电？
IEC 国际标准规定的镍氢电池的标准充 放电为： 首先将电池以0.2C放电至1.0V/支， 然后以0.1C充电16小时，搁置1小时后， 以0.2C放至1.0V/支，即为对电池标准充 放电。

AA Alkaline/Rechargeable Ni-MH BatteriesThe following describes the proper use of batteries and how to prolong their life. Incorrect use can shorten battery life or cause leakage, overheating, fi re, or explosion.■Cautions: Handling the Batteries• Do not expose to water, fl ame, or heat, or store in warm or humid condi-tions.• Do not transport or store with metal objects such as necklaces or hairpins.• Do not disassemble or modify the batteries or battery casing.• Do not subject to strong physical shocks.• Do not use batteries that are leaking, deformed, or discolored.• Keep out of reach of infants and small children.• Insert in the correct orientation.• Do not mix old and new batteries, batteries with diff erent charge levels, or batteries of diff erent types.• If the flash will not be used for an extended period, remove the batteries. Note that fl ash settings will be reset.• The batteries may be warm to the touch immediately after use. Turn the flash off and allow the batteries to cool before handling.• Battery capacity tends to decrease at low temperatures. Keep spare bat-teries in a pocket or other warm place and exchange as necessary. Cold batteries may recover some of their charge when warmed.• Fingerprints and other stains on the battery terminals can impair battery performance. Thoroughly clean the terminals with a soft, dry cloth before inserting them in the flash.If the batteries leak, clean the battery chamber thoroughly before inserting new batteries.If fl uid from the battery comes into contact with skin or clothing, fl ush the aff ected area with water. If fl uid enters your eyes, immedi-ately fl ush the aff ected area with water and seek medical attention.Donot rub your eyes.Failure to observe this precaution could result in per-manent visual impairment.■Ni-MH BatteriesThe capacity of Ni-MH batteries may be temporarily reduced when new, af-ter long periods of disuse, or if they are repeatedly recharged before being fully discharged. This is normal and does not indicate a malfunctio n.The flash draws a small amount of current even when off . Ni-MH batteries that have been left in the flash for an extended period may be drawn down to the point that they no longer hold a charge. Battery performance may also drop if the batteries are run down in a device such as a fl ashligh t. B atteries that no longer hold a charge even after repeatedly being discharged and recharged have reached the end of their service life and must be replaced.Ni-MH batteries can be recharged in a battery charger (sold separately). Bat-teries may become warm to the touch after charging. Refer to the instructions provided with the charger for more information. Use the charger with compat-ible batteries only.Ni-MH batteries gradually lose their charge when not in use.■DisposalDispose of used batteries in accord with local regulations.Liquid CrystalIn the event that the display is damaged, care should be taken to avoid con-tact with liquid crystal. Take the urgent action indicated should any of the following situations arise:• If liquid crystal comes in contact with your skin, clean the area with a cloth and then wash thoroughly with soap and running water.• If liquid crystal enters your eyes, fl ush the aff ected eye with clean water for at least 15 minutes and then seek medical assistance.• If liquid crystal is swallowed, rinse your mouth thoroughly with water. Drink large quantities of water and induce vomiting, then seek medical assistance.Caring for the FlashTo ensure continued enjoyment of the product, observe the following pre-cautions.■Storage and UseIf the fl ash will not be used for an extended period, remove batteries. Do not store or use the fl ash in locations that are:• exposed to rain, steam, or smoke• very humid or extremely dusty• exposed to direct sunlight or very high temperatures, such as in a closed vehicle on a sunny day• extremely cold• subject to strong vibration• exposed to strong magnetic fi elds, such as near a broadcasting antenna, power line, radar emitter, motor, transformer, or magnet• in contact with volatile chemicals such as pesticides• next to rubber or vinyl products■Water and SandExposure to water and sand can also damage the fl ash and its internal cir-cuitry and mechanisms. When using the fl ash at the beach or seaside, avoid exposing the fl ash to water or sand. Do not place the fl ash on a wet surface.■CondensationSudden increases in temperature, such as occur when entering a heated building on a cold day, can cause condensation inside the fl ash. If this occurs, turn the fl ash off and wait for the condensation to evaporate.■CleaningUse a blower to remove dust from the fl ash window, then gently wipe with a soft, dry cloth. Any remaining stains can be removed by wiping gently with a piece of FUJIFILM lens-cleaning paper to which a small amount of lens-cleaning fl uid has been applied. Care should be taken to avoid scratching the fl ash, particularly the fl ash window. The body of fl ash can be cleaned with a soft, dry cloth.Thank you for your purchase of a FUJIFILM EF-42 clip-on fl ash unit.Please read this manual thoroughly before using the product.■Using the FlashAfter mounting the fl ash on the camera, do not pick the camera up by the fl ash. The fl ash may become separated from the hot shoe, causing the camera to fall.For information on compatible cameras, visit our website at http:// /products/digital_cameras/index.html • M aximum fl ash output equivalent to a GN of 42/138 (ISO 100, m/ft): Auto zoom () automatically matches fl ash angle to lens focal lengths in the 24–105 mm range (35 mm format equivalent).• Flexible bounce-fl ash lighting: The fl ash head can be rotated 90° ver-tically, 180° left, or 120° right to provide bounce-flash lighting in nearly all situations.• Exposure compensation: Exposure compensation of ±1.5 EV gives free rein to your creative powers. Choose from settings of –1.5, –1, –0.5, 0, +0.5, +1, and +1.5 EV.• Adjustable fl ash output: Manual flash level adjustment gives you a choice of full output ( / ) or / , / , / , / , / , / of full power.• Adjustable focal length display: Lens focal can be displayed during shooting either in APS-C () or 35 mm () format.• Built-in wide panel: With coverage for focal lengths as short as 20 mm (35 mm format equivalent), the EF-42 can also be used for wide-angle shots.For Your Safety (14)Table of Contents (16)Principal Features (16)Parts of the Flash (17)Inserting Batteries (18)Attaching the EF-42 (18)Auto Power Off (18)The LCD Display (19)Through-the-Lens (TTL) Flash Photography (20)Adjusting Settings (21)Manual Flash Photography (22)Using the Wide Panel (23)Bounce Lighting (23)Continuous Use (24)Specifi cations (24)*Lights to assist the focus operation if the shutter button is pressed halfway when lighting is poor.May not light with some cameras.Built-in wide panelFlash windowBattery-chamber coverAF-assist lamp *Lock ringLCD displayThe EF-42 can be used with lithium, alkaline, nickel-metal hydride (NiMH), and Oxyride batteries.

各种电池的区别
各种电池的区别电池分类依材质区分■碳锌电池Heavy Duty Battery亦称为锌锰电池，是目前最普遍之干电池，它有价格低廉和使用安全可靠的特点，基于环保因素的考量，由于仍含有镉之成份，因此必须回收，以免对地球环境造成破坏。
■碱性电池Alkaline Battery亦称为碱性干电池，适用于需放电量大及长时间使用。
电池内阻较低，因此产生之电流较一般锰电池为大，而环保型含汞量只有0.025%，无须回收。
■水银电池Silver Oxide Button Cell水银电池，因为污染和电容量之故线已逐渐被锂-锰配方取代■锂电池■镍镉充电电池Ni-Cd(Nickel Cadmium Battery)已为大众早期广泛使用，可重覆约500次之充放电，但约10次充放电后即会产生记忆效应；另一个缺点是，在充放电时，阴极会长出镉的针状结晶，有时会穿透分隔物而引起内部枝状晶体式的短路。
由于含有镉之成份，因此必须回收。
■镍氢充电电池Ni-MH(Nickel Metal Hyoride Battery)为目前市场主流之充电电池，它是使用氧化镍作为阳极，以及吸收了氢的金属合金作为阴极，一般可进行500次以上的充放电循环。
由于不含汞及镉之原料，不必回收。
■锂充电电池Rechargeable Lithium ion Battery■铅酸电池Sealed Lead-Acid Battery■太阳能电池在化学电池中，根据能否用充电方式恢复电池存储电能的特性，可以分为一次电池（也称原电池）和二次电池（又名蓄电池，俗称可充电电池，可以多次重复使用）两大类。
一次电池又可分为普通锌锰（中性锌锰）、碱性锌锰、锌汞、锌空、镁锰和锌银六个系列；二次电池主要有镍镉电池、镍氢电池、锂离子电池、碱锰充电电池和铅蓄电池等类型。
在数码设备中，常用的电池类型是干电池（包括碱性电池）、镍镉电池、镍氢电池和锂离子电池等。
干电池：这是使用最普遍的电池类型之一，很多人用过干电池，但了解其构造的人却不多。
Battery 简介
3. 正極的裂解反應生成氧氣,使得內部壓力升 高,容易造成電池的形變. 4. 正極的裂解反應的固態生成物CO2O3 與 CoO附著在正極表面,氧氣溶於電解液阻 礙鋰離子的移動,皆不利於充放電反應進行. 此種變化使得內阻值增加,壓縮了 鋰電池可利用的電壓範圍,造成電池容量的 降低.
過放電的影響: 負極: CYLiX→xLi++xe沒有不良影響. 將Li+從石墨的層狀結構中完全 抽離並不會損壞石墨結構, 結構安定並俱良好 導電能力是石墨被選為負極材料的主要原因 之一. 正極: Li1-xCoO2+xLi++xe-→LiCoO2 鋰離子電池的放電反應, 鋰離子由負極移動到正 極嵌入Li1-xCoO2層狀結構的空洞,當空洞填 滿,多餘的Li+就沉積在正極表面形成鋰金屬 結晶.
锂离子电池以其高可靠性，高能 量密度及较高的工作电压在现代生 活中扮演着越来越重要的角色，锂 离子电池与液昌显示器，半导体一 起作为现代电子工业的三个核心器 件推动了电子器件向轻量化，小型 化和便携化方向的快速发展。
鋰離子電池充放電原理
由下圖可適切地表達出鋰離子電池的充 放電反應原理.當充電時由外界輸入能量 ﹝電能﹞，鋰離子由能量較低的正極材 料趕往負極材料中而成為能量較高的狀 態。進行放電時，鋰離子自然地出能量 較高的負極材料移往能量較低的正極材 料而對外釋放能量﹝電能﹞。另外，從 全反應式中也可瞭解到整個反應過程中 沒有鋰金屬的存在，因此稱之為鋰離子 電池。
END&THANKS!!!
為什麼電池廠商建議對過度放電的鋰離子電池採小電 流充電? 當鋰離子電池過度放電後,大電流充電與小電流充電 最主要的差異在於鋰金屬結晶的溶解量.大電流充 電會迫使LiCoO2 參與充電反應釋出Li+,能快速的 回復鋰離子電池的電壓.但是,卻會留下較多的鋰金 屬結晶,使得電池容量下降.同時鋰金屬結晶也會在 後續的充放電反應中繼續增長,最後刺破隔離膜造 成內部短路. 事實上,即便是小電流充電,鋰金屬結晶依然會殘留在 正極上,也同樣會在後續的充放電反應中繼續增長, 最後刺破隔離膜造成內部短路.只是相對於大電流 需要更長的時間來堆積鋰金屬而已. .

鎳氫電池結構和原理
迪比科工程部
鎳氫電池由氫氧化鎳正極，儲氫合金負極，隔膜紙，電解液，鋼殼， 頂蓋，密封圈等組成。在圓柱形電池中，正負極用隔膜紙分開捲繞在一起 ，然後密封在鋼殼中的。在方形電池中，正負極由隔膜紙分開後疊成層狀 密封在鋼殼中。
電池容量越高越好嗎 ？ 不同型號(特別是不同體積)的電池,他的容量越高,提供使用的時間越長.拋開體積和重 量的因素,當然容量越高越好. 但是同樣的電池型號,標稱容量(比如600mAh)也相同,實際測的初始容量不同:比如一個 為660mAh,另一個是605mAh,那麼660mAh的就比605mAh的好嗎. 實際情況可能是容量高的是因為電極材料中多了增加初始容量的東西,而減少了電極穩 定用的東西,其結果就是迴圈使用幾十次以後,容量高的電池迅速容量衰竭,而容量低的 電池卻依然堅挺.許多國內的電芯廠家往往以這個方式來獲得高容量的電池.而用戶使用 半年以後待機時間卻是差得一塌糊塗. 民用的那些AA鎳氫電池(就是五號電池),一般是1400mAh,卻也有標超高容量的(1600mAh), 道理也 是一樣. ★提高容量的代價就是犧牲迴圈壽命,廠家不在電池材料的改性上下文章,是不可能真正 "提高"電池容量的.
究竟買何種充電器要根據你的DC耗電情況，你的備用電池數，你的存儲卡的大小，拍照 的習慣甚至你的個性來決定。 這裏要提醒大家的是，根據我的實際經驗，決定我每次外出拍攝的時間長短的不是電池 ，而是我的存儲卡的容量!---我用A60，一組電池(4節次世代2100)能把128M卡拍滿還有 多的，我沒有筆記本電腦，所以相對於我的卡說，電池足夠用了，同時也沒必要多花買 快充----對我來說8-10小時充滿就夠了。 但如果你是個急性子，或者是喜歡“掃射“的拍照方式，那就要買快充或多配幾組電池 了。 另外要說明的是：慢充因為較安全，所以在選購時可以不必要求很知名的品牌；但快充 較危險，出於對你的人身、財產及電池安全的考慮，建議不要購買雜牌的!! 快充中最著名的就是三洋系列的了，從M53，54,55到M60，都很不錯，其他如超霸的，次 世代也可以，同時聽說鵬輝的快充性價比也很高。 現在100分鐘左右充満4節2100電池的充電器有不少，如三洋M60，超霸快速充電器，次世 代白金四驅套裝，鵬輝快充等，價格從250到60元，另外需要注意的是：一般快速充電器 都有充電時間限制(保護)，所以能一次充滿的電池容量是有限制的!不過可以二次充電的 辦法解決。

Plug one end of the power cord or car charging adapter into the D4 charger. Plug the other end of the cord into an applicable outlet. The LCD display and all battery indicator bars will illuminate as the charger runs a quick self-test. When testing is complete, the name of the product will appear on the screen, the bars will dim and the charger will enter into stand-by mode. If no batteries are detected within 1 minute, the charger will automatically enter Eco Mode (the LCD backlight will turn off). When a battery is installed while in Eco Mode, simply press any button to activate the LCD display.2. The D4 features four charging slots, each of which charges and monitors a battery independently. Rechargeable batteries of differing chemistries and voltages may be charged simultaneously using either 1, 2, 3 or all 4 of the charging slots. When inserting a battery, ensure the positive and negative ends correspond with the positive (+) and negative (-) symbols on the charger. Incorrect installation will result in failure to initiate the charging process.Note: The D4 is capable of charging 3.7v Li-ion rechargeable cells, 1.2v, Ni-MH/Ni-Cd rechargeable batteries and 3.2v LiFePO4 batteries. See above for description of battery sizes.3. When a battery is first inserted the D4 will run a short test causing the battery indicators bars to illuminate in sequence from the bottom to the top. When the test is complete, the D4 will enter into charging mode. If any unusual circumstances have been detected, e.g. a backward battery installation, the battery indicator bars will blink rapidly and “Err” will be presented on the screen to urge an immediate removal of the battery.4. While in charging mode, the battery indicator bars will blinkrhythmically to indicate the on-going charging process. The battery’s power status and charging progress is indicated by the number of bars that illuminate steadily. The LCD display will also displaybattery voltage, followed by charging current and elapsed charging time in sequence. Pressing the side “MODE” button will cyclethrough these charging parameters. To view the charging progress of a different charging slot press the side “SLOT” button to select a desired slot. When charging is complete, all five battery indicator bars will illuminate steadily and “Chg.Finish” will appear on the LCD display.Note: When the D4 is charging three or four batteries, chargingcurrent will be set to 375mA. Alternatively, when charging either one or two batteries, charging current will be set to 750mA.Charging LiFePO4 batteriesTo charge LiFePO4 batteries, simply press and hold the side“MODE” button for more than 2 seconds right after the battery test completes and “LiFePO4” will appear on the LCD display to indicate the activation of LiFePO4 charging mode. To exit LiFePO4 charging mode, simply press and hold the side “MODE” for more than 2 seconds once again, or remove and reinstall the battery.Charging Small Capacity BatteriesWhen charging batteries with a capacity lower than 750mAH (e.g. AAA, 10440 and 16340 batteries), a low charging current is recommended to help extend battery life.SYSMAX Industry Co., Ltd.TEL: +86-20-83862000 FAX: +86-20-83882723 E-mail: *****************Web: Address ： Rm1401, Glorious Tower, 850 East Dongfeng Road,Guangzhou, China 510600Please follow our facebook for more info: NITECORE Flashlights®The All-Round Flashlight ExpertTo select a low charging current, while in regular charging mode, simply press the side “SLOT” button to select a desired battery slot and then press and hold the side “MODE” button for more than 1 second until “LOW” is displayed on the LCD display indicating activation of low current charging mode. To exit, simply press and hold the side “MODE” button for more than 1 second once again or remove and reinstall the battery.Nocturnal Charging ModeWhen charging a battery overnight, nocturnal charging mode is recommended. Simply press and hold the side “SLOT” button for more than 1 second in any state until the LCD backlight turns off thus activating nocturnal charging mode. This feature ensures a peaceful night’s sleep without being disturbed by the D4’s LCD backlight and blinking LEDs. To exit nocturnal mode and turn the backlight on again, press and hold the side “SLOT” button for more than 1 second again.Battery ActivationFor every installed battery, the D4 will activate the battery bycharging it for 6 seconds at a low current. If zero voltage is detected, “Err” will be displayed on the LCD screen. If activation fails the first time, please remove and reinstall the battery once again and activate for the second time.Note: The D4 is not recommended for use with over-discharged (zero volt) UNPROTECTED Li-ion batteries. Li-ion batteries without a protection circuit can potentially cause a fire or explosion.Overtime PreventionThe D4 is equipped with an advanced ‘overtime’ safety function. The D4 will individually monitor the elapsed charging time for each battery slot and if a particular slot exceeds 20 hours, the D4 will automatically power off the slot and display full charging bars to indicate completion of the charging process. This feature reduces the risk caused by batteries of lesser quality.Precautions1. The D4 is compatible with batteries of varying sizes, therefore when charging certain batteries (such as 26650 and AAA), manual adjustment of the battery’s position within the slot is recommended, as to ensure solid contact is made between both sides of the battery and the charging slot’s metal contact points.2. The D4 is restricted to charging Li-ion, IMR, LiFePO4,Ni-MH/Ni-Cd rechargeable batteries only. Never use the D4 with other types of batteries as this could result in battery explosion,cracking or leaking, causing property damage and/or personal injury. 3. The D4 should only be used indoors or inside a motor vehicle and under no circumstances should it be exposed to water, high humidity and low or high ambient temperatures.4. Do not disassemble or modify the charger.5. Children under the age of 18 should be supervised by an adult when using the D4.6. The D4’s safe operating temperature is between 0ºC--40ºC 。

镍氢可充电电池以及充电电路
镍氢可充电电池以及充电电路Ni-HM Rechargeable Battery and Charger 上个星期，充电器莫名其妙地坏了，折腾了几天终于修复好了，从中了解到了不少的知识，所以写下来与大家分享。
那可是当年一千多买的外语通9188原装充电器，用了至少五年了吧，效果感觉很好，可是怎么就不明不白的挂了呢？于是自己拆开检修，里面一块电路板，上面电阻、电感、电容和二极管、三极管都还挺多，还有一个核心IC（AZ339比较器），果真不赖。
大致一看，并没有发现任何异常现象，且用万用表测变压器的220V输入端貌似开路。
然后初步判定是变压器坏了，当买回来新变压器的时候才想起来不是变压器的问题，因为在接通和断开电源的瞬间，指示灯会闪一下，而且再用万用表一测，变压器的220V输入端阻抗很大，但并未开路。
没搞清楚状况就下结论，真2。
再看了看充电电路板，崭新的，没有任何元件有损坏的迹象。
花了半天的时间把电路画了出来，又测量、分析了半天，越是糊涂了。
觉得整个充电电路的设计好奇怪，不知道是什么原理，真纳闷以前她是怎么正常充电的，而且效果也不错。
这两天在网上看到了一些关于可充电电池，充电电路之类的资料。
觉得原理挺清晰，也不是很麻烦，于是决定要拯救我的充电器。
下面是一个镍氢电池的典型充电电路。
1.基准电压Vref形成外接电源经插座X、二极管VD1后由电容C1滤波。
VD1起保护作用，防止外接电源极性反接时损坏TL431。
R3、R4、R5和TL431组成基准电压Vref，根据图中参数Vref= 2.5×(100+820)／820=2.80(v)，这个数据主要是针对镍氢充电电池而设计(单节镍氢充电电池充满后电压约为1.40V)。
2.大电流充电(1)工作原理接入电源，电源指示灯LED(VD2)点亮。
装入电池(参考图片，实际上是用导线引出到电池盒，电池装在电池盒中)，当电池电压低于Vref时，IC1-1输出低电平，VT1导通，输出大电流给电池充电。
