This paper reviews about the bidirectional on-board chargers for electric vehicles. The chargers are of two types: on-board chargers and off-board chargers. The overall size, weight and cost of the onboard chargers can be reduced using integrated on-board chargers where the drive train components are used for propulsion as well as for charging. Four-quadrant operation of the drive is possible using the bidirectional converters in the drive train. Regenerative braking control in the integrated on-board chargers aids in proper utilization of braking energy, which in turn increases the driving range of the vehicle. Various on-board chargers are presented and their working, advantages and limitations are discussed here.

本文介绍了电动汽车的双向车载充电器。充电器有两种类型：车载充电器和非车载充电器。使用集成的车载充电器可以减少车载充电器的整体尺寸，重量和成本，在该集成车载充电器中，传动系组件既用于推进又用于充电。使用传动系统中的双向转换器，可以实现四象限运行。集成式车载充电器中的再生制动控制有助于适当利用制动能量，从而增加了车辆的行驶里程。介绍了各种车载充电器，并在此讨论了它们的工作，优点和局限性。
