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 connecting unit is arranged between every two adjacent battery packs, the connecting units are located above the upper surfaces of the battery packs and located on one side of the bicycle beam, and the connecting units are used for detachably connecting the battery units and the bicycle beam. According to the invention, power can be supplied to a heavy-weight electric vehicle; the overall height of the battery unit is reduced; the battery replacement requirement of a large-weight electric vehicle is met, the safety and stability of connection between the large-size battery pack and the vehicle beam are improved, and the situation that the battery unit deforms due to the fact that the middle area of the battery unit is lack of support is avoided; the bearing point of the battery pack is matched with the vehicle beam, so that the connecting structure between the battery unit and the vehicle beam is simplified, the bearing strength of the vehicle beam to the battery pack is improved, and the mounting and dismounting device is suitable for mounting and dismounting battery units with various external dimensions.
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;相邻两个电池包之间设有连接单元,连接单元位于电池包的上表面上方,且位于车梁的一侧,连接单元用于将电池单元与车梁可拆卸连接。采用本发明,能够对大重量的电动车辆进行供电;降低了电池单元的整体高度;适应大重量的电动车辆的换电需求,提高了大尺寸电池包与车梁连接的安全性和稳定性,避免因电池单元的中间区域缺少支撑导致电池单元发生变形;电池包的承重点与车梁相配合,简化了电池单元与车梁之间的连接结构,提高了车梁对电池包的承载强度,适应多种外型尺寸的电池单元的安装和拆卸。
