The invention discloses a power pack for an electric bus, which includes a battery box and a number of power supply modules arranged inside the battery box. The outer walls of the left and right sides of the battery box are provided with an air inlet on one side, and on the other side. There is an air outlet, and the air inlet communicates with the inside of the battery box through the ventilation holes on the battery box. There are several air inlets for the outside air to enter on the air inlet; the air outlet also connects to the battery box through the ventilation holes on the battery box. The interior is connected, there are several air outlets on the air outlet, and a fan for blowing air is installed at the air outlet; the inner wall of the battery box is provided with a heat-resistant radiation coating and a thermal insulation cotton layer in turn, and the power module is located inside the thermal insulation cotton layer , A battery heating module is installed at the bottom of the power module. Aiming at the problem that the performance and service life of the electric vehicle power supply module are affected by the use in the environment of too high or too low temperature, the present invention proposes a power pack for electric bus with functions of heat dissipation, heating and heat preservation.
Description
technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a power pack for an electric bus. Background technique [0002] As the energy situation becomes increasingly severe and people's awareness of environmental protection gradually strengthens, power modules and power systems for electric vehicles and other fields are continuously developed and improved. In view of the current continuous promotion and use of electric vehicles, considering the limitations of power supply systems in high or low temperature conditions and the reliability of battery cells, the heat dissipation and heating functions of power supplies have attracted more and more attention. Therefore, people try to solve the heat dissipation and heating problems of the power module by improving some battery pack equipment. For example, the patent authorization announcement number is CN202009061U, and the authorization announcement date is October 12, 2011. T...
