| 摘要： | A battery is actually an assembly of cells (pictured above): each stores electrical energy at a particular voltage, and the battery has enough cells connected in series to give the desired voltage. Cell voltage depends on its chemistry: a lead-acid cell has a nominal voltage of 2.1V, so six cells are needed for a '12V car battery. Nickel metal hydride (NiMH) runs at 1.2V, while a typical lithium-ion cell has a voltage of 3.2V. An electric vehicle's traction battery might run at 300V, so 94 cells would be needed -although for packaging purposes 96 cells is more likely. |
