[0049] For example, the distribution box monitors the current in the circuit based on the output current obtained. When the output current obtained by the distribution box exceeds the set threshold, the distribution box triggers the protection device to cut off or limit the current to prevent equipment damage or safety accidents such as fire.

[0050] Based on the above embodiment, the cumulative power consumption monitoring device also includes: the charging control unit 03 is also hard-wired to the low-voltage power supply 01 and the battery 02 respectively, and the charging control unit 03 is also used to obtain voltage information of the low-voltage power supply 01 and / or the battery 02.

[0051] Specifically, in addition to establishing a communication connection with the current sensor 04 through a communication protocol, the charging control unit 03 also establishes a hard-wired connection with the low-voltage power supply 01 and the battery 02 through physical cables. Through the hard-wired connection, the charging control unit 03 directly samples the voltage of the low-voltage power supply 01 and / or the battery 02 to obtain the voltage information of the low-voltage power supply 01 and / or the battery 02.

[0054] In the embodiment of the present invention, the current power may be understood as the rate at which electric energy is consumed at a specified time or time period, and is used to calculate the corresponding accumulated power consumption.

[0055] Specifically, the current data in the parallel circuit is obtained through the current sensor 04, and the rated measured output voltage is determined based on the current data by the current sensor 04, and the rated measured output voltage is reported to the charging control unit 03. The charging control unit 03 determines the current information based on the rated measured output voltage, and the charging control unit 03 directly samples the voltage in the circuit through a hard line to obtain the voltage information in the circuit.

When the vehicle is normally powered, the vehicle is only powered by the battery 02. At this time, the current information in the parallel circuit collected by the current sensor 04 is only the current value when the battery 02 is powered. When the vehicle is in the ON gear, the vehicle is powered by the battery 02 and the low-voltage power supply 01 at the same time. At this time, the current information of the parallel circuit collected by the current sensor is the current value of the battery 02 and the low-voltage power supply 01 simultaneously powering the vehicle.

The vehicle controller LAN bus exchanges and communicates data based on the vehicle controller LAN bus protocol. For example, the vehicle controller LAN bus communicates with the charging control unit 03 based on the vehicle controller LAN bus protocol. The charging control unit 03 also communicates and shares data with other components within the system through the vehicle controller LAN bus, thereby realizing the coordinated work of the components within the system.

[0059] Specifically, the charging control unit 03 establishes a communication connection with the vehicle controller LAN bus and / or the cloud platform through a communication protocol. Through the communication connection, the charging control unit 03 exchanges and communicates data with the vehicle controller LAN bus and / or the cloud platform. The charging control unit 03 directly collects the voltage information of the parallel circuit of the low-voltage power supply 01 and the battery 02 through a hard-wired connection, obtains the rated measured output voltage determined by the current sensor 04 through the communication connection, determines the current information based on the rated measured output voltage, and the charging control unit 03 generates a cumulative power consumption based on the current information and the voltage information, and transmits the generated cumulative power consumption to the vehicle controller LAN bus and / or the cloud platform. The vehicle controller LAN bus and / or the cloud platform performs subsequent data processing and data feedback based on the cumulative power consumption reported by the charging control unit 03.

[0060] For example, the charging control unit 03 reports the accumulated power consumption to the vehicle controller LAN bus through the vehicle controller LAN bus protocol, the vehicle controller LAN bus analyzes and processes the accumulated power consumption, and the vehicle controller LAN bus adjusts the vehicle's operating status and fault detection based on the accumulated power consumption; the charging control unit 03 transmits the accumulated power consumption to the cloud platform through the communication protocol, the cloud platform stores, analyzes and processes the accumulated power consumption, and sends the result feedback back to the vehicle.

The charging control unit calculates the current power in real time through the voltage information and current information in the normal power state, and generates cumulative power consumption based on the current power.

[0085] When the switch signal is valid, the charging control unit is awakened to power on the low voltage. When the electrical state of the whole vehicle is in the ON gear state, the battery and the low-voltage DC jointly serve as the low-voltage distribution unit to output electrical energy to supply energy to the whole vehicle. At this time, the current sensor is responsible for sampling the current output by the parallel circuit of the battery and the low-voltage DC to obtain the current data of the parallel circuit, and generating the rated measured output voltage based on the collected current data of the parallel circuit. The rated measured output voltage is input to the charging control unit to obtain current information. The charging control unit directly samples the voltage output by the parallel circuit of the battery and the low-voltage DC through a hard line to obtain voltage information. The charging control unit calculates the current power in real time by sampling the voltage information and current information in the ON gear state, and generates the accumulated power consumption based on the current power.
