perc电池常用规格
perc电池常用规格英文回答：Perc batteries, also known as lithium iron phosphate (LiFePO4) batteries, are a common type of rechargeable battery. They are widely used in various applications such as electric vehicles, renewable energy storage systems, and portable electronic devices.The most common specification for Perc batteries is the voltage and capacity. The voltage of a Perc battery can range from 3.2V to 3.3V per cell. For example, a typical Perc battery pack for an electric vehicle may consist of multiple cells connected in series to achieve a higher voltage, such as 48V or 72V.The capacity of a Perc battery is measured in ampere-hours (Ah) or milliampere-hours (mAh). It represents the amount of energy the battery can store and deliver. Perc batteries can have a wide range of capacities, from a fewhundred mAh for small portable devices to several thousand Ah for large energy storage systems. For instance, a Perc battery used in a smartphone may have a capacity of around 3000mAh, while a Perc battery used in a home energy storage system may have a capacity of 10kWh or more.In addition to voltage and capacity, other important specifications of Perc batteries include the maximum discharge current, the maximum charge current, and the cycle life. The maximum discharge current refers to the maximum amount of current that the battery can deliver continuously without damaging the cells. The maximum charge current refers to the maximum amount of current that can be used to charge the battery. The cycle life represents the number of charge-discharge cycles that the battery can undergo before its capacity significantly degrades.Perc batteries offer several advantages over other types of rechargeable batteries. They have a higher energy density, which means they can store more energy in a smaller and lighter package. They also have a longer cycle life and better thermal stability, making them more durableand safer to use. Additionally, Perc batteries have a lower self-discharge rate, which means they can retain their charge for a longer period of time when not in use.中文回答：Perc电池，也被称为磷酸铁锂（LiFePO4）电池，是一种常见的可充电电池。

Over-current protective function: The protective IC can monitor the current, if the real-time current over limitation, IC will start up current-limiting function to protect the whole PCBA and battery. Generally, over-current ≥ 1.5 * rated output current. Over-charging protective function: The protective IC can monitor the battery charging process, and with the function to cut off charging circuit automatically once fully charging. For general battery, the fully charging voltage is 4.2V Over-discharging protective function: The protective IC can monitor the whole discharging process, discharging circuit can be cut off automatically once battery voltage reaching the lower limit. For general Li-ion battery, the lower limit voltage at around 2.75V ~ 3.0V
