The type of power battery

Lithium-ion battery (Li-ion): The most commonly used type of power battery in electric vehicles, with high energy density and long cycle life.

锂聚合物电池（LiPo）：类似于锂离子电池，但具有一些优点，例如更轻更薄。

NiMH电池：曾经是混合动力和电动汽车中常用的一种电池类型，价格相对较低，但能量密度较低。

Lead-acid battery: A traditional type of power battery, mainly used in hybrid and some low-speed electric vehicles.

Solid-state battery: A new type of battery technology with higher safety and energy density, but currently at a higher cost.

Each battery type has its advantages and disadvantages, and choosing the right EV battery depends on the vehicle's needs, performance requirements, and cost considerations.
