Temperature control structure of battery box of electric bus

Abstract

The invention discloses a temperature control structure of a battery box of an electric bus. The temperature control structure comprises a battery box body, a heat dissipation device and a temperatureadjusting system. According to the invention, heat dissipation holes in the battery box body are covered with heat dissipation grids, the heat dissipation grids are opened in hot weather, and the heat dissipation grids are closed in cold weather, so the effects of ventilation and heat dissipation of the battery box body in summer and heat preservation and heat insulation of the battery box body in winter can be achieved, and the service life of a battery is prolonged; the temperature adjusting system is arranged and comprises a processor, a data storage module, a safety detection module, a temperature adjusting module, a fault detection module and an early warning control module; and the temperature adjusting system not only can detect and adjust the temperature of the battery box body, but also can detect the fault of the battery and feed back battery problems to a user, so the user can monitor the battery in real time, and the service life of the battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of battery boxes for electric buses, in particular to a temperature control structure for the battery boxes of electric buses. Background technique [0002] At present, there are two main heat dissipation methods for the battery box of electric buses: air-cooled and water-cooled. Among them, the air-cooled method is widely used, that is, by installing a cooling fan inside the box and opening cooling holes on the box, the box will The internal heat is exhausted to the outside of the battery case. This heat dissipation method has an obvious disadvantage, that is, when the cold weather comes in winter, the power battery pays more attention to the thermal insulation function. Since each battery box has a cooling hole, the heat inside the battery box will pass through the cooling hole. The rapid emission to the outside of the battery box cannot play the role of heat insulation, which increases the time area for ...

Problems solved by technology

This heat dissipation method has an obvious disadvantage, that is, when the cold weather comes in winter, the power battery pays more attention to the thermal insulation function. Since each battery box has a cooling hole, the heat inside the battery box will pass through the cooling hole. Distributed quickly to the outside of the battery box, it cannot play the role of heat insulation, and increases the time area for the power battery to work in a low temperature environment, thereby affecting the service life of the power battery
