New energy vehicle motor controller provided with capacitor and busbar integrated module

Abstract

The invention provides a new energy vehicle motor controller provided with a capacitor and busbar integrated module. The new energy vehicle motor controller comprises the capacitor and busbar integrated module, a controller box body (11), an inverter module (12), an input terminal (13), an output terminal (14) and a capacitance output flexible flat cable (15), wherein the capacitor and busbar integrated module comprises a capacitor (1), an upper layer copper bar (3), a lower layer copper bar (4), a capacitance stand column (5) and a wire connecting block (6); the upper layer copper bar (3) and the lower layer copper bar (4) are arranged from top to bottom, the positions, corresponding to the capacitance stand column (5), of the copper bars (3, 4) are provided with gaps (7) for connecting the copper bars (3, 4) and the capacitance stand column (5), output shafts (2) are arranged in the middles of the copper bars, and the output shafts (2) are connected with the capacitance output flexible flat cable (15). By the adoption of the new energy vehicle motor controller, the size of an original product is reduced, and the vibration reliability of the relevant devices is improved greatly.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to a new energy vehicle motor controller with a capacitor bus integrated module. Background technique [0002] Traditional industrial motor controllers mainly focus on the electrical performance of the product itself, such as the accuracy and efficiency of motor control. With the development of new energy vehicles, because the motor controller of new energy vehicles has further requirements on the shock resistance and volume of the product itself, the design of some core components in traditional motor controllers can no longer meet the needs of new energy vehicles. For example, the capacitor connections in traditional motor controllers are generally scattered and connected by spot welding. During the driving process of the car, collisions and frictions are prone to occur, resulting in dangers such as desoldering and short circuits. Therefore, it is urgent to improve it. Cont...

With the development of new energy vehicles, because the motor controller of new energy vehicles has further requirements on the shock resistance and volume of the product itself, the design of some core components in traditional motor controllers can no longer meet the needs of new energy vehicles

For example, the capacitor connections in traditional motor controllers are generally distributed and connected by spot welding. During the driving process of the car, collisions and frictions are prone to occur, resulting in dangers such as desoldering and short circuits. Therefore, it is urgent to improve it.
