Embodiment Construction

[0020] On-board composite power supply system, used to supply power for the AC and DC loads of the RV or as a power supply for the electrical system of the car, such as figure 1 shown. The power system includes:

[0021] Solar battery pack 1 and controller 3, vehicle-mounted DC generator 2 and isolator 4, bidirectional DC-DC converter 8, supercapacitor pack 9, storage battery pack 10, AC-DC converter 12, gasoline / diesel generator 15, Shore power AC 16, intelligent management controller 11 and touch LCD screen 7, DC output interface 5, critical AC output interface 13, critical 220V AC load 14, non-critical AC output interface 17, and non-critical AC load output interface 18.

[0022] The solar battery pack 1 is connected to the low-voltage DC bus through the controller 3, the vehicle-mounted DC generator 2 is connected to the low-voltage DC bus through the isolator 4, and the low-voltage terminal of the bidirectional DC-DC converter 8 and the supercapacitor group 9 are connect...

Abstract

The invention provides a vehicle-mounted compound power source system which comprises a solar battery pack, a gasoline or diesel generator unit, a storage battery pack, a super capacitor bank, an alternate-direct current converter, a two-way direct-alternate current converter, an alternate current power supply port, a direct current power supply port and an intelligent management controller. A compound power source sufficiently utilizes the rapid-charging characteristic of a super capacitor, and rapid energy storage is rapidly conducted on the super capacitor through a vehicle-mounted power generator and the solar battery pack. Meanwhile the storage battery pack is charged through the two-way direct-alternate current converter, and the storage battery pack is charged by shore power and thegasoline or diesel generator unit through the alternate-direct current converter. The compound power source system can utilize the shore power, the gasoline or diesel generator unit, the vehicle-mounted direct-current power generator and the solar battery pack to directly provide an alternate current power source and a direct current power source for external loads, and when all other energy sources are not provided, the storage battery pack can be utilized to provide the alternate current power source and the direct current power source for the external loads.

Description

technical field [0001] The invention generally relates to the electrical application field of vehicles, in particular to the electrical assembly system of a caravan and a power supply vehicle. Background technique [0002] At present, most of the power supplied to electrical equipment by the power supply system of RVs and power vehicles is provided by gasoline or diesel generators, or the camp (base) provides power protection, and batteries are used as energy storage devices. When the energy storage device of the power system runs out of electricity, it is necessary to replenish and charge the battery in time to supply electric energy and store energy again. Due to the limitation of the inherent charging and discharging characteristics of the battery, to achieve instantaneous high power output and fast energy storage, the power system based on the battery alone cannot meet the requirements of use. Therefore, how to quickly supplement electric energy from multiple ways and p...
