Auxiliary power controller used for electric automobile

Abstract

The invention discloses an auxiliary power controller used for an electric automobile. The auxiliary power controller comprises a rectifying module, an absorption capacity module, a high-voltage charging module, a main capacitor module, a voltage balancing absorption module, a control module, a drive module, an IGBT module, a Hall sensing module and an auxiliary power supply module. The auxiliary power controller is stable in work, high in adaptability and reliability and can better meet the requirement of drivers for control comfort.

Description

technical field [0001] The invention relates to the field of electronic control of electric vehicles, in particular to an auxiliary power controller for electric vehicles. Background technique [0002] Today, with increasing energy saving and consumption reduction, it is the general trend to vigorously develop electric vehicles. Due to the complex electronic control system of electric vehicles, the performance requirements of each component are very high. Therefore, continuous technological innovation and product upgrades are the top priority for improving products and winning the market. In electric vehicles, the auxiliary controllers other than the main drive controller are the core components for controlling direction and braking, and play a vital role in the car. [0003] However, the existing auxiliary power controllers for electric vehicles only have two parts: the drive board and the control board. The high-voltage impact when the vehicle's electronic control system...
