摘要
驱动器是电动汽车的三大核心部件之一,对整车的性能及安全可靠性起着非常重要的作用。为提高驱动器的可靠性,从元器件/零部件的选用控制、降额设计、热设计、抗震动设计、容错设计等多方面对电动汽车驱动器进行专门的强化设计及优化;本驱动器设计完成后,试制样机完成了台架实验及装车路试,达到了设计指标。提出在不明显增加产品BOM成本的情况下,本驱动器能达到车用级实用产品水平,从而为探索电动汽车驱动器的设计提供一种新思路。
Driver is the one of three core parts of electric vehicle. It plays a very important role to the electric vehicle performance and safety reliability. In order to improve reliability of driver, electric vehicle driver has been special reinforcement designed and opmitized from selection of elements/components, derating design, thermal design, anti-shock design and fault-tolerant design. After electric vehicle driver design completed, platform experiment was completed,and the design target was met by loading and road-test. It is pointed out that without significantly increasing the BOM cost of the product, the vehicle-applicable level is achieved thereby providing a new idea for exploring the design of electric vehicle driver.
