The invention belongs to the technical field of new energy electric vehicles, and particularly relates to a cold region pure electric vehicle maintenance and battery maintenance method. According to the cold region pure electric vehicle maintenance and battery maintenance method, a lithium iron phosphate battery is selected to be used for an operating vehicle in a cold region, a battery pack is charged and discharged regularly in 7-8 days, and the battery capacity is balanced; and dust is regularly removed from the whole vehicle in 5-7 days to avoid short circuit of an electric circuit causedby excessive dust. The lithium iron phosphate batteries of 66 new energy pure electric passenger vehicles, the ternary lithium battery of a new energy pure electric passenger vehicle and the lead-acidbatteries of two new energy pure electric vans are used and maintained by our team, we find that the attenuation rate of the maintained new energy pure electric vehicle is reduced by 3% compared withthat of a vehicle battery which is not maintained. The technology is suitable for being popularized and used in the related technical field.

    本发明属于新能源电动车技术领域,具体是一种寒区纯电动汽车维护及电池保养方法。本发明寒区纯电动汽车维护及电池保养方法,选用磷酸铁锂电池用于寒冷地区的运营车辆使用,7‑8天定期对电池组进行充放电,均衡电池容量;5‑7天定期全车清除灰尘,避免灰尘过多造成用电线路短路。经过我们团队对66辆新能源纯电动客运汽车磷酸铁锂电池、一辆新能源纯电动乘用车三元锂电池、两辆新能源纯电动箱式货车铅酸电池的使用和对电池的保养,经过维护及保养后的新能源纯电动车比没经过维护及保养的车辆电池衰减率降低3%,本发明技术适合在相关技术领域推广使用。
