Abstract

The invention discloses a vehicle-mounted multi-power-supply charging and discharging management board card and system, and relates to the technical field of power management, and a CAN transceiver, an MCU controller and three switching devices are integrated on the board card; one end of each of the first switching device and the second switching device is configured as a power input, and the other end is configured as a corresponding power output; two ends of the third switching device are respectively connected with the other ends of the first switching device and the second switching device; one end of the third switching device is configured as a generator input and a generator output, or the two ends of the third switching device are configured as the generator input and the generator output respectively; the first switching device, the second switching device and the third switching device are all controlled by the MCU controller; the CAN transceiver is configured to receive engine state information and send message information; and the MCU controller is configured to drive the switch-on and switch-off of each switch device according to the message information. The technical problem that large arrangement space is needed in multi-power-supply charging and discharging management can be solved.

Description

technical field [0001] The present application relates to the technical field of power management, and in particular, to a vehicle-mounted multi-power charge and discharge management board and system. Background technique [0002] Traditional fuel vehicles often use lead-acid batteries to start the engine or power the vehicle, and also require a generator to charge the lead-acid batteries. Generally speaking, the maximum storage capacity of lead-acid batteries is 80-200Ah, so different types of vehicles can choose lead-acid batteries of corresponding capacity according to the power consumption of the whole vehicle to meet the power supply requirements of the current model. [0003] As far as commercial vehicles are concerned, they are generally used in medium and long-distance transportation, and two lead-acid batteries are used in series to output 24V DC. In practice, when drivers stay in the car for a long time, they also need some household appliances to meet their daily...
