Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted power management, and in particular relates to a multi-power management and control device for commercial vehicles. Background Art

[0002] With the increase of on-board electronic and electrical equipment, especially the continuous expansion of on-board additional equipment, the power consumed by various electronic and electrical equipment is increasing, and the on-board power supply is developing in a diversified and complex direction. In order to ensure the safe and reliable power supply of various electronic equipment by the vehicle and improve the service life and efficiency of various power supplies, intelligent multi-power supply management and control devices are needed to coordinate the work of various power supplies. Therefore, the design of on-board multi-power supply management and control devices has become an important part of the design of the entire power supply system;

[0003] According to a vehicle-mounted power supply device proposed in the patent publication number CN 111566890 B, when the output voltage of the vehicle battery is less than the lower limit value of the starting voltage, the storage unit is charged by the power supplied from the outside to the non-contact power receiving unit, and the power charged to the storage unit is supplied to the control unit via the discharge unit, so that the control unit can be started. After the control unit is started, the battery relay unit uses the power supplied from the storage unit via the discharge unit and is controlled to a connected state by the control unit. By supplying power from the high-voltage battery to the vehicle battery, the vehicle battery can output a voltage above the lower limit value, so that multiple relay units can be connected;

[0004] Traditional vehicle power systems are unable to make intelligent judgments under complex working conditions based on the vehicle's power supply status and load status combined with power replenishment needs, battery power loss, power loss compensation and low temperature, resulting in uneven power distribution in the vehicle.

[0005] Therefore, those skilled in the art have proposed a multi-power supply management and control device for commercial vehicles to solve the problems raised by the background technology.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content
