Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicle auxiliary equipment and relates to an electric vehicle controller. Background Art

[0002] Electric vehicle controllers are a crucial component of electric vehicles. Currently, wireless modularization is increasingly common. However, there is a persistent conflict between the optimal electrical layout of modular controllers and the requirements for vehicle installation. For example, the motor phase and Hall lines run the same route to the motor, and the positive and negative power supply terminals and functional lines are aligned in roughly the same direction. However, the current optimal electrical layout for controllers doesn't align well with the requirements for vehicle lead-out wiring. Therefore, two approaches are currently being adopted to address this issue: 1. The controller's terminal blocks are moved to a more convenient location for vehicle installation, with internal conductive copper connections, which increases costs. 2. The electric vehicle wiring is lengthened, increasing costs. Furthermore, the inconsistent routing leads to twisted wires, resulting in cluttered wiring on site. Summary of the Invention
