The invention discloses a double-battery power supply electric automobile capable of changing battery in a trunk, which comprises the trunk, an electric automobile and an operation power supply. One end of a second high-voltage direct-current relay is electrically connected with a trunk battery pack. The other end of a first high-voltage direct-current relay and the other end of the second high-voltage direct-current relay are both connected with one end of an inverter in series, and the other end of the inverter is connected with a motor in series. By arranging a power supply system formed by double battery packs which are the chassis battery pack and the trunk battery pack, the cruising ability of the electric automobile can be greatly improved, battery replacement and charging can be carried out without disassembling the chassis, and the trunk battery pack is fixed through a battery mounting groove of a fastening spring; the first high-voltage direct-current relay and the second high-voltage direct-current relay are matched for control, so that the chassis battery pack and the trunk battery pack can be conveniently and freely switched for energy supply, and timely automatic switching is facilitated.

    本发明公开了一种可后备箱换电的双电池供电的电动汽车,一种可后备箱换电的双电池供电的电动汽车,包括后备箱、电动汽车和操作电源,所述第二高压直流继电器的一端与后备箱电池组之间电性连接,所述第一高压直流继电器和第二高压直流继电器的另一端均串联有逆变器的一端,所述逆变器的另一端与马达串联。本发明通过设置底盘电池组和后备箱电池组的双电池组形成的供电体系,可以大幅度提高电动汽车的续航能力,无需拆卸底盘的方式进行电池更换充电和利用固紧弹簧的电池安装槽来固定后备箱电池组,第一高压直流继电器和第二高压直流继电器配合控制,以方便自由切换底盘电池组与后备箱电池组供能,便于及时自动切换。
