Increasing the weight of the car will consume most of the car's energy consumption on its own weight. Below 100 km / h, the weight factor determines 80% of the power consumption. Above 100 km / h, the wind resistance Become the main factor of power consumption. The International Aluminum Association report states that for every 10% reduction in the vehicle's own weight, power energy consumption can be reduced by 6% to 8%.
当前新能源电动汽车动力电池正负极连接普遍采用铆接工艺，铆接时内部增加普通结构陶瓷作为垫圈，以达到电解液与外壳绝缘密封效果，较为先进技术为采用环状陶瓷，上下端面实施金属化，使陶瓷具有可焊性，从而达到正负极与电池外壳连接但绝缘的效果；以上两种方案虽能解决动力电池正负极与外壳绝缘连接、密封电解液的效果，但会增加动力电池模组的整体高度及在车内的整体重量，使得整车重量增加，耗能增加。At present, the positive and negative connections of new energy electric vehicle power batteries generally use riveting technology. During the riveting, ordinary structural ceramics are added as gaskets to achieve the insulation and sealing effect of the electrolyte and the shell. The ceramics can be welded, so that the positive and negative electrodes are connected to the battery case but are insulated; although the above two solutions can solve the effects of positive and negative electrodes of the power battery and the case insulation and seal the electrolyte, they will increase the power battery The overall height of the module and the overall weight inside the vehicle increase the weight of the vehicle and increase energy consumption.
