Title:
MULTI-POWER SUPPLY HYBRID POWER SUPPLY AND POWER DISTRIBUTION CONTROL SYSTEM OF TRAVEL TRAILER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/082475
Kind Code:
A1
Abstract:
A multi-power supply hybrid power supply and power distribution control system of a travel trailer and a control method therefor, the system comprising a power supply detection module, a combined logic controller, a PFC controller, an AC/DC converter, a DC/DC converter, an inverter boost circuit and a storage battery. In the method, detection and identification are carried out during multi-power supply hybrid power supply, mains electricity or an external generator is preferentially used for supplying power to an electrical appliance. Meanwhile, a storage battery for daily use is charged and the storage battery for daily use is controlled not to discharge to achieve the aim of saving the limited energy inside of a trailer. When only driving power generation or an auxiliary power supply is present, the storage battery is charged. When the electrical energy of the storage battery is limited, the storage battery of an original travel trailer maintains basic lighting and low-energy consumption electrical appliances inside of the travel trailer, and the storage battery for daily use supplies power to electronic devices having higher energy consumption. Thus, power supply and power distribution are more reasonable and efficient, which increases the utilization rate of electrical energy, prolongs the usage service life of a storage battery for daily use, improves maintenance efficiency, and has a broad space for use and development.
