Description

Technical Field

[0001] The utility model relates to the field of charge and discharge control, and in particular to an energy storage charge and discharge device with multiple batteries connected in parallel. Background Art

[0002] The charging and discharging devices in energy storage equipment will generate heat during operation. If this heat cannot be dissipated in time, it will cause the equipment to overheat, thereby affecting the performance of the equipment and may even cause risks such as equipment damage or fire.

[0003] Most current charging and discharging devices use built-in cooling fans for heat dissipation. However, when the charging and discharging device is charging or discharging, other devices will also generate a lot of heat, which will lead to unsatisfactory heat dissipation of the charging and discharging device and affect the performance of the device.

[0006] Preferably, a sealing strip is provided in the docking groove.

[0007] Preferably, the air outlet is composed of evenly distributed small holes.

[0008] Preferably, both ends of the base plate are provided with a screw hole, and the fixing plate is provided with fastening screw holes corresponding to the screw holes one by one. The base plate can be mounted on the fixing plate by fitting bolts with the screw holes and the fastening screw holes.

[0009] Beneficial effects: The device cools the internal electrical components by introducing external cold air, solving the problem of poor heat dissipation caused by excessively high internal temperature; and ribs are provided on the fixing plate for easy positioning, and the ribs cooperate with the long holes for quick positioning and installation.
