Embodiment

[0024] Example: such as figure 1 and figure 2 As shown, the upper opening of the box body 20, the box cover 21 and the box body 20 are fastened together, the inner surface of the bottom of the box body 20 is provided with a plurality of support feet 22 of equal height, and the lower insulating plate 23 is supported on the upper ends of the support feet 22 , the supporting feet 22 support the lower insulating plate 23, so that a certain distance is formed between the lower insulating plate 23 and the inner surface of the box body 20, and the mounting screws for installing various DC contactors, insurances, time relays, etc. are pre-installed. A certain space is left to prevent the screws from touching the bottom inner surface of the box body, so as to ensure that the lower insulating plate 23 is evenly arranged. A motor power control system, an air conditioner power control system, a charger power control system, a DC conversion device control system and a heating power contr...

Abstract

The invention relates to a high-voltage electric box, in particular to a high-voltage electric box used for a pure electric automobile. The high-voltage electric box comprises a box body and a box cover. A motor power supply control system, an air-conditioner power supply control system, a charger power supply control system and a direct current conversion device power supply control system are arranged in the box body. The motor power supply control system has the following structure that: an anode of a motor controller bus is connected with an anode of a power battery through a first direct current contactor and a first direct current fuse which are connected in series, and a cathode of the motor controller bus is connected with a cathode of the power battery through a second direct current contactor; a pre-charge resistor and a third direct current contactor are connected in series between two ends of the second direct current contactor, and the third direct current contactor is controlled by a normally closed contact end of a time relay; and a normally open contact end of the time relay controls a control end of the second direct current contactor.

Description

technical field [0001] The invention relates to a high-voltage electrical box, in particular to a high-voltage electrical box used in pure electric vehicles. Background technique [0002] The application of a large number of automobiles in the world has produced and caused serious environmental and human survival problems. People are committed to developing efficient, clean and safe means of transportation, and new energy vehicles such as electric vehicles, hybrid vehicles, and fuel cell vehicles have been proposed as representative means of transportation to replace traditional vehicles in the future. However, the prior art does not provide an integrated high-voltage electrical box applicable to pure electric vehicles. Contents of the invention [0003] The invention solves and provides an integrated high-voltage electrical box with good performance applied to pure electric vehicles, and solves the technical problems existing in the prior art. [0004] The above technic...
