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.

Lithium polymer battery (LiPo): Similar to lithium-ion batteries, but with some advantages, such as being lighter and thinner.

NiMH Battery: Once a common type of battery used in hybrid and electric vehicles, it was relatively inexpensive but had a lower energy density.

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.
