一种无需外部电源的电动汽车车载锂离子电池低温交流加热器

In cold climates, lithium-ion batteries suffer severe power/energy loss, bad performance, and reduced life cycle. Many internal ac heating strategies have been proposed to provide fast heating with a higher efficiency and better uniformity. However, the ac current is typically generated by an offboard equipment with grid power supply, which is a main bottleneck of the ac heating applied to electri...
