Abstract

The invention relates to a service battery charging management device and method for power supply of a recreational vehicle. The management device comprises an automobile generator, a solar cell panel, an MCU master control unit, an input automatic switching unit, a charging main conversion DC / DC circuit, a service battery, a pulse width modulation mode charging unit and a load. The MCU master control unit controls the input automatic switching unit according to the output voltage of the solar cell panel and the output voltage of the automobile generator to enable the solar cell panel and theautomobile generator to selectively serve as the charging power supply of the service battery and to enable the service battery to maintain an optimal charging state, thereby ensuring normal power supply for living electricity consumption in the recreational vehicle.

Description

technical field [0001] The invention relates to the field of caravan power supply, in particular to a service battery charging management device and method for caravan power supply. Background technique [0002] The RV power supply system generally includes two systems: one is the car generator and starting battery, which is used to supply power to the car starter motor, headlights, and on-board systems; the other is the service battery, which mainly provides lighting, pedals, and water pumps for the interior of the RV. Electricity for life. The current application mainly connects the starting battery and the service battery through a switch. When the vehicle is running, the car generator charges the starting battery, and at the same time charges the service battery through the switch closure. When the engine stops, the switch is disconnected, and the service battery alone provides power for the RV life lighting, water pump, etc. [0003] At present, most RVs use the clean...
