[0023] See attached picture.
[0024] figure 1 Schematic diagram of the equal wheelbase of the electrical box. It can be seen from the figure that the electrical box body (1) and the electrical box cover (2) form a whole to cover and protect the internal electrical components. All connectors are arranged in the electrical box On the side wall; the electrical box body and the electrical box cover are connected by bolts, and there is a gasket to ensure the protection level of the electrical box.
[0025] figure 2 It is the left view of the electrical box. It can be seen from the figure that the heating system connector (4) and MSD (24) are arranged in front of the electrical box. The heating system is used to heat the battery system before charging, and the MSD (24) is used for maintenance. Or in case of an accident, manually disconnect the high pressure circuit.
[0026] image 3 It is the right view of the electrical box. It can be seen from the figure that the battery hi...

A battery system power distribution box framework integrated with a charging interface comprises an electric appliance box body, an electric appliance box cover, a high-low-voltage internal electric device, a high-low-voltage external connector, a support, a fast-charging socket, a slow-charging socket, a manual service disconnect (MSD), a battery control unit (BCU) and a battery thermal management relay, and is characterized in that an electric appliance box is a single component and is used for managing a power battery and distributing a direct-current power supply of the power battery to other electricity utilization components. The framework has the advantages that the structure is simple, the design is reasonable, and the relay, electric accessories of the relay, the MSD, a current sensor, the fast-charging socket, the slow-charging socket and all electric devices are highly integrated; the current sensor is used for collecting charge and discharge and heating current; the electric appliance box is independently designed into an independent component so that a battery pack can be standardized, and the universality of the battery pack can be improved; the electric appliance boxis independently arranged, so that the electric arrangement of a whole vehicle is more flexible; most electric devices on a battery system are integrated, so that later repair and maintenance are facilitated.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to the design and structural design of the electric framework applicable to the battery system of the electric vehicle. Background technique [0002] At present, electric vehicle electrical box is mostly integrated in the battery pack or the electrical components are scattered in other components such as PCU. The above causes the inside of the battery pack to increase the size of the battery pack, and makes the versatility of the battery pack worse; based on the above background, the present invention provides a battery system power distribution box architecture with integrated charging interface, which can be arranged as a separate component on the chassis of the car In fact, this greatly improves the applicability of the battery pack, and integrates the battery system-related relays, sensors, fuses, charging sockets and other components together to facilitate maintenance...
