Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] Such as figure 1 , figure 2 A high-voltage power distribution box for an electric vehicle shown in the box, the main circuit and the vehicle controller 1 are arranged in the box, and the main circuit ( figure 1 The part surrounded by the dotted line) includes a pair of battery input terminals 5 for connecting the power battery pack, a pair of charging input terminals 4 for connecting the charger, and a pair of main motor output terminals 6 for connecting the main motor controller. A pair of electrical accessory output ports 13 for connecting electrical accessories. The above-mentioned input terminals and the negative terminals of the output terminals share the same ground (in the figure, the output terminals 4, 5, 6, and 13 of each input terminal also represent the corresponding devices, such as 6 also represents the host controller itself), and the...

The invention relates to a high-tension distribution box for a pure electric vehicle. The high-tension distribution box comprises a box body, wherein a main circuit and an entire vehicle controller (1) are arranged in the box body; the main circuit comprises a pair of battery input ends (5) for connecting a power battery pack, a pair of charging input ends (4) for connecting a charger, a pair of main motor output ends (6) for connecting a main motor controller, and at least one pair of electric accessory output ends (13) for connecting electric accessories. The high-tension distribution box for the electric vehicle disclosed by the invention can be used for charging a pure electric passenger car, distributing current to the main motor controller and an electric accessory load and providing a pre-charging circuit for a high-voltage system capacitive load of the entire vehicle, and plays a role in protecting, so that the safety and stability of an electric vehicle power supply system are greatly improved.
Description
technical field [0001] The invention relates to a high-voltage distribution box of an electric vehicle. Background technique [0002] With the world's energy shortage and the enhancement of human awareness of environmental protection, energy saving and new energy vehicles have become the theme of today's development, and pure electric vehicles have become the main development direction in China. However, the high-voltage distribution box of pure electric buses is only a simple Power distribution function, no protection function and error-proof design function, so there are certain risks in the batch production of pure electric vehicles. Since the production characteristics of passenger cars are mainly semi-automated and manual, and the voltage level of pure electric vehicles is relatively high, the fault tolerance is very low. However, with the increase in market demand for pure electric buses, manual production is easy. Lead to assembly errors, resulting in safety accident...
