How many kilowatt-hours are needed to fully charge a 500 km range?
1 Answers
60 kilowatt-hours approximately. Classification of electric vehicle batteries: Electric vehicle batteries are divided into two major categories: storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. Fuel cells are specifically used for fuel cell electric vehicles, including alkaline fuel cells (AFC), phosphoric acid fuel cells (PAFC), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC), proton exchange membrane fuel cells (PEMFC), and direct methanol fuel cells (DMFC). Functions of storage batteries: The functions vary slightly depending on the type of electric vehicle. In pure electric vehicles equipped only with storage batteries, the storage battery serves as the sole power source for the vehicle's drive system. In hybrid vehicles equipped with traditional engines (or fuel cells) and storage batteries, the storage battery can act as either the primary power source or an auxiliary power source for the drive system. Thus, at low speeds and during startup, the storage battery functions as the primary power source for the drive system; during full-load acceleration, it serves as an auxiliary power source; and during normal driving, deceleration, or braking, it acts as an energy storage device.
