Embodiment

[0035] see image 3 , Figure 4 , Figure 5 , Image 6 , the high-voltage power input by the power battery enters the high-voltage power distribution box through the single-core connector (9, 10), and the positive power goes through the 450V 150A fuse E13, the DC relay five to the terminal G, and passes through the PCU+ (Power Control Unit) The line outlet is sent to the positive pole of the motor controller, and the negative electricity is directly connected to a copper bar in the high-voltage power distribution box. The copper bar serves as all negative circuits in the power distribution box except for the low-voltage power. The PCU-slinger port is sent to the negative pole of the motor controller.

[0036] The direct current enters the box body through the fast charging connectors (2, 3). The positive electricity goes through the 450V 100A fast charging fuse 14 and the DC relay 4. It is connected to the BDU+ (Battery Disconnect Unit) through the F terminal of the fuse E...

Abstract

The invention relates to an easy-to-maintain compact high-voltage distribution box, and belongs to overall high-voltage electrical systems of new energy automobiles. The distribution box is suitable for electrical automobiles with a plurality of high-voltage components (motors, electrical air conditioners, PTC, DC / DC and the like). The distribution box comprises a box body, a fuse wire, a DC relay, a high-voltage connector, an insulating board, a wiring terminal and cable accessories. When the entire automobile adopts a plurality of high-voltage electrical devices at the same time, the distribution box provided by the invention can safely and effectively distribute the electrical energy output by power batteries, and has the advantages that the connector can be plugged in and out easily, the inner part of the box body can be checked conveniently, the fuse wire can be replaced conveniently, double-gear PTC control is realized, the insulating performance is good, and the distribution box is safe and compact.

Description

technical field [0001] The invention relates to a high-voltage power distribution system for new energy vehicles, which is suitable for new energy vehicles with multiple high-voltage electrical components (motor, electric air conditioner, PTC and DC / DC, etc.) Problems, especially related to a compact high-voltage power distribution box that is easy to repair. Background technique [0002] With the continuous development and improvement of new energy vehicle technology, the number of high-voltage electrical components used in the vehicle is increasing. It is required that the power battery can safely supply power to multiple electrical appliances at the same time, and this process should have certain controllability. To realize this function, it is necessary to connect multiple high-voltage cables in parallel on the high-voltage bus, and design a fuse protection circuit and a DC relay in the circuit to realize the control function. In view of the requirement of compact vehic...
