This application provides an interface circuit of a vehicle-mounted control unit comprising an H-bridge circuit, an input branch, and a pull-up network. An input end of the H-bridge circuit is connected to a controller 240, and an output end of the H-bridge circuit is connected to an interface port IO of the interface circuit. A first end of the input branch is connected to the interface port IO, and a second end of the input branch is connected to the controller.

A novel busbar, suitable for low-power applications, features a u-shaped extension having a male terminal that fits into and establishes electrical connection with a standard female terminal. The housing of an electrical box including the busbar is modified to receive the female terminal in such a way that Ingress Protection ratings of IP67 and IP69K are maintained within the electrical box. The busbar is not riveted to a thicker busbar terminating with a stud and lug nut, as in legacy configurations, thus being simpler and cheaper to manufacture. The female terminal, once connected to the busbar, is removable by inserting a tool into a dedicated opening within the housing.

To achieve a reduction of power consumption by stopping an inter-node data input/output process and node processing by autonomous control of each node without using a management table. Included are a data processing unit that performs predetermined processing on data input from an upstream node; and a data output management unit that outputs, to a downstream node, the data on which the predetermined processing has been performed in the data processing unit, and monitors a state of the downstream node. The data output management unit controls the data processing unit to stop the data processing in a case of detecting that there is no downstream node using the output data. The stop of node processing and inter-node data input/output are performed upstream in a chain manner.

A modular power distribution system for use on a vehicle having an electric power source. The system includes a power distribution block having a switch socket with a first format, a device socket having a second format, associated with the switch socket to form a socket pair, a relay electrically coupling the switch socket to the device socket, and input power terminals electrically coupled to the socket pair and the relay, and configured to be electrically coupled to the electric power source. A switch wire harness includes a switch plug having a first complemental format configured to be removably received by the first format of the switch socket. A device wire harness includes a device plug having a second complemental format configured to be removably received by the second format of the device socket.

A protective housing for a central electrical system deployed within an electric vehicle is described. The protective housing features a first housing layer, a second housing layer and a third housing layer. The first housing layer is configured to support and protect one or more power distribution units responsible for distributing high-voltage power to components within the electric vehicle. The second housing layer is positioned above the first housing layer, where the second housing layer is to support and protect a power charger that disseminates supplied input power to a high-voltage junction box for routing to the battery system of the vehicle. The third housing layer is positioned above the second housing layer, where the third housing layer is to support a high-voltage junction box that handles the routing of power between the distribution unit(s), the charger and the battery system.
