Retired battery echelon utilization energy storage device

Abstract

The invention discloses a retired battery echelon utilization energy storage device. The device comprises a main box, vertical plates are fixedly connected to the two sides of the interior of the main box, a plurality of transverse plates are fixedly connected between the vertical plates on the two sides, a capacitor is arranged on one side of each transverse plate, a connecting assembly is arranged on the other side of each transverse plate, and an air cooling system and a water cooling circulation system are arranged on the main box. According to the retired battery echelon utilization energy storage device, air circulation in the main box is accelerated through a heat dissipation fan, so that heat dissipation is accelerated, meanwhile, the heat dissipation fan moves in the main box along with a lifting mechanism and a translation mechanism, the action area of the heat dissipation fan is increased, and the heat dissipation effect of the heat dissipation fan is further improved; and under the action of a water pump, water in a water tank flows through the main box through a water pipe and then returns into the water tank, a water circulation system is formed; when the water flows in the water pipe in the main box, heat in the main box is absorbed and brought out of the main box, the heat dissipation efficiency in the main box is further improved, and the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the technical field of decommissioned batteries, in particular to an energy storage device for cascade utilization of decommissioned batteries. Background technique [0002] The cascading utilization of decommissioned batteries refers to the continued use of batteries on electric vehicles after they have been used for a long time, and the performance of the batteries cannot meet the needs of the vehicle, and then the functions are fully or partially restored by other methods, or the remaining electric energy of the batteries is concentrated. Storage and reuse are used in other scenarios. Energy storage mainly refers to the storage of electric energy. With the gradual depletion of energy, the storage and reuse of energy has become the key to solving the problem of energy waste.

Problems solved by technology

[0003] During the discharge process of the decommissioned battery in the energy storage device, the heat is more serious than that of the power battery. If the heat cannot be dissipated in time, the temperature of the battery will rise. On the one hand, the battery efficiency of the decommissioned battery will be reduced; The heat dissipation method of the existing energy storage device is often through heat conduction and natural heat dissipation through the heat dissipation plate, and the heat dissipation efficiency is poor. Therefore, the present invention provides a decommissioned Battery cascade utilization energy storage device
