The invention belongs to the field of new energy automobiles, and discloses a new energy automobile battery setting method, which can control the significant expansion or recovery of the output current of a new energy battery through the on-off of a switch, thereby greatly improving the power performance and acceleration performance of the new energy automobile. The power-type battery pack is connected in series between the pair of output nodes through the first switch, so that the power-type battery pack and the energy-type battery pack can be disconnected and connected in parallel, the power-type battery pack and the energy-type battery pack are thermally isolated, and the power-type battery pack has better charging and discharging capability than the energy-type battery pack, so that the power-type battery pack can be charged and discharged based on actual requirements. The power-type battery pack and the energy-type battery pack are connected in parallel by switching on and off the first switch, so that the total output current of the new energy battery can be increased, and the power-type battery pack and the energy-type battery pack cannot generate mutual heat influence due to cold isolation. The invention further discloses the automobile battery pack based on the setting method.

    本发明属于新能源汽车领域,公开了一种新能源汽车电池设置方法,通过开关开断,能够控制新能源的电池输出电流的显著扩大或回复,从而大大提高了新能源汽车的动力性能和加速性能,设置功率型电池组,通过第一开关将功率型电池组串入一对输出节点之间,使得功率型电池组和能量型电池组形成可断开的并联,并使得功率型电池组、能量型电池组热隔离,功率型电池组相较于能量型电池组具有好的多的充放电能力,从而基于实际需求,通过开断第一开关将功率型电池组与能量型电池组形成并联,能够使得新能源的电池输出总电流增大,并且冷隔离使得功率型电池组和能量型电池组不会产生相互的热影响。本发明还公开了基于上述设置方法的一种汽车电池包。
