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.
