The electric vehicle comprises a vehicle beam and a battery unit, and the battery unit comprises a plurality of battery packs arranged side by side in the width direction of the vehicle beam; a locking unit is arranged on the bicycle beam, a connecting unit is arranged between every two adjacent battery packs corresponding to the bicycle beam, and the connecting units are matched with the locking units so that the battery units can be connected with the bicycle beam in a locking mode. According to the invention, the battery unit is provided with a plurality of battery packs, so that power can be supplied to a heavy-weight electric vehicle; and when the large-weight electric vehicle is subjected to battery replacement, the whole battery unit can be replaced, so that the quick replacement requirement of the large-weight electric vehicle is met. And the joints of the battery units and the vehicle beam can be positioned in the space between the battery packs, so that the connection stability is improved. In addition, the locking unit is arranged on the vehicle beam, the battery unit can be replaced at the bottom of the vehicle, and sufficient space is reserved for battery replacement of the battery replacement equipment.
本发明公开了一种电动车辆,电动车辆包括车梁和电池单元,电池单元包括沿着车梁的宽度方向并列设置的多个电池包;车梁上设有锁止单元,与车梁对应的相邻两个电池包之间设有连接单元,连接单元与锁止单元相配合,以将电池单元与车梁锁止连接。采用本发明,电池单元具有多个电池包,能够对大重量的电动车辆进行供电;而在对大重量的电动车辆进行换电时,能够对电池单元整体进行更换,以适应大重量的电动车辆的快换需求。也能够使得电池单元与车梁的连接处位于电池包之间空间内,提升连接的稳定性。另外,在车梁上设置锁止单元,能够在车辆的底部对电池单元进行更换,为换电设备的换电预留出充分的空间。
