[Abstract]: One kind of electric automobile intelligence fleetness charger design process the main body of a book has been introduced. Be a charger's turn to control middle owing to that the C8051F040 of Cygnal company monolithic machine being to control core , the proper dummy load module , high-accuracy A/D change C8051F040 , functions such as I2C highway interface and high speed PWM applies to battery charging. And be a charger's turn to implant μC/OS-II real
time OS and adopt to move the each other complete bridge soft the switch host circuit topology,have higher efficiency, electric current , voltage strain are small , job stability is reliable. Whose hardware and the software design process the main body of a book has been given an account of detailedly.

1、引言
电池是电动汽车的关键动力输出单位,在铅酸蓄电池,镍镉电池,镍氢电池,锂电池和
燃料电池等几种常用电池中,因为具有能量比大、重量轻、温度特性好,污染低,记忆效果不明显等特点,铅酸蓄电池、镍氢电池在电动汽车中使用很普遍。然而由于充电方法的不正确,造成充电电池的使用寿命远远低于规定的寿命。也就是说很多电池不是被用坏的而是被充坏的,可见充电器的好坏对电池寿命有很大的影响。基于此,本文提出一种使用C8051F040单片机智能充电控制方案的智能充电器的设计,能有效的提高充电效率,延长电池的使用寿
命。
