Abstract: This paper reviews new energy technologies for electric

vehicles, including battery technology, motor control technology,

and charging technology. Battery technology is the core

technology of electric vehicles, divided into lithium-ion batteries

and fuel cells. Lithium-ion batteries are currently the mainstream

choice for electric vehicles, with advantages including high energy

density, long life, high efficiency, and low emissions. Fuel cells are

a new type of battery technology that can convert hydrogen and

oxygen into electrical energy with no pollution or noise, but practicality is currently limited. Motor control technology is a key

technology for electric vehicles, divided into DC motor control and

AC motor control. DC motor control is simple and low cost,

suitable for small city cars; AC motor control technology is more

mature and suitable for a wide range of large electric vehicles.

Charging technology includes AC charging and DC charging, with

fast charging speed and high cost for DC charging technology,

suitable for long-distance travel; AC charging technology is low

cost, safe and reliable, suitable for home and company charging.

Keywords: electric vehicles, new energy technology, battery

technology, motor control technology, charging technology.
