Electric vehicle controller with good performance

Abstract

The invention discloses an electric vehicle controller with good performance, and belongs to the technical field of electric vehicle controllers, the electric vehicle controller comprises a controller shell, a controller body is installed in the controller shell, a heat conduction mechanism is installed between the controller body and the outer wall of the controller shell, and a ventilation mechanism is installed between the top of an inner cavity of the controller shell and the controller body. A protection mechanism is installed on the side, away from the controller shell, of the heat conduction mechanism, and a shell cover is installed at the opening end of the controller shell through bolts. When the temperature of the controller body is low, the ventilation mechanism is in a closed state, heat preservation of the controller body is facilitated, the dustproof purpose is achieved, heat generated by the controller body at ordinary times exchanges heat with the outside through the heat conduction mechanism, the heat dissipation purpose is achieved, and when the temperature of the controller body is very high, the ventilation mechanism is automatically started, and the ventilation mechanism is automatically started. Therefore, forced ventilation and heat dissipation are carried out on the controller body, the controller body is kept at a proper temperature, and stable performance of the controller body is ensured.

[0002] With the advancement of science and technology and the development of society, electric vehicles are loved by people as a new energy green environmental protection product. Electric vehicles are a kind of battery-powered The electric vehicle controller is one of the most important parts of the electric vehicle. The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. , it is like the brain of an electric vehicle and is an important part of an electric vehicle. The current electric vehicle controllers are directly fixed on the electric vehicle and are in direct contact with the outside air. Long-term use will cause dust accumulation, and high temperature and Low temperature will affect the performance of the controller, and the controller directly exposed to the outside world cannot guarantee the stability of its own temperature. In summer, the natural heat dissipation is slow, which may easily lead to high-temperature aging of the controller. In winter, the outside temperature is very low, which affects the control. The working efficiency of the capacitance and electrical components in the device will affect the performance stability of the controller. Therefore, we propose a good performance electric vehicle controller to solve the above problems
