动力电池气密检测标准与IP68的关系

目前各大主机厂动力电池布置方案均为将动力电池布置在车辆底盘下方,起到节省车内空间、降低车辆重心、保证汽车行驶平稳性的作用.动力电池作为纯电动车的唯一动力来源,是高能量体零部件.目前续驶里程超过600 km的纯电动汽车,电量均在100 kW·h左右,任何水和灰尘进入动力电池内部都可能导致内部短路,会引起着火爆炸的风险,危...

The Relationship Between Airtight Test of Power Battery and IP68

At present,almost every OEM places the power battery under the vehicle chassis in order to save space,lower center of gravity and ensure the driving stability of the vehicles.Power battery is the only power source of the EVs,which brings high energy.At present,the pure electric vehicle with an mileage endurance of more than 600 km has a power of about 100 kW•h or so.Any intrusion of water and dust entering the power battery may cause internal short circuit,w-hich will cause the risk of fire and explosion.It may endanger the personal safety of passengers.Therefore,it is very important to ensure that the air tightness test standard and the power battery meet IP68.The purpose of this paper is to find out the relationship between the air tightness test standard of power battery and IP68,ensure that the power battery meets the requirements of IP68,and ensure the safety of power battery and passengers.
