Battery Terminology
• Cells, modules, and packs • Ampere-hour (Ah) capacity • State of charge (SoC) • Depth of discharge (DoD) • State of health (SoH) • Cycle life
2.2 Construction and Principle 结构与原理
Most current production HEVs use nickel-metal hydride (NiMH) battery as the high-voltage power battery. NiMH batteries are being used for these applications because of their performance characteristics such as specific energy, cycle life, and safety. From a manufacturing perspective, the NiMH battery is attractive because the materials used in its construction are plentiful and recyclable.
Construction A lead-acid battery consists of positive plates,
negative plates, separators, electrolyte and case, see Figure 2.1.

2.2.2 Nickel-metal hydride (NiMH) battery镍氢电池
Most battery and hybrid electric vehicles use dualvoltage electrical systems. The high-voltage (HV) system is used to power the electric drive (traction) motor, while a conventional 12-volt system is used to power all other aspects of vehicle operation. One advantage to using this system is that the vehicle can use any conventional electrical accessories in its design.
