Description

A vehicle-mounted energy storage system Technical Field

[0001] This invention relates to the technical field of energy storage vehicles, and in particular to the technical field of an on-board energy storage system. Background Technology

[0002] Currently, large-scale outdoor events generally require temporary power supply, which is usually provided by diesel or gasoline generator sets. These generator sets can affect the event itself and the environment due to noise and exhaust. Fuel leaks may pollute the soil and water sources. High-temperature components and improper oil storage can easily cause fires or explosions. Using them in enclosed spaces may lead to carbon monoxide poisoning.

[0003] Chinese patent application number 201922352361.3 discloses a compact diesel generator set, including a low-speed diesel engine, a planetary gearbox, a generator, an auxiliary cooling fan, and a base. The low-speed diesel engine and the generator are fixedly installed at both ends of the base. The power output shaft of the low-speed diesel engine is coaxially arranged opposite to the rotor shaft of the generator. The planetary gearbox is fixedly installed in the middle of the base. The low-speed shaft of the planetary gearbox is drivenly connected to the power output shaft of the low-speed diesel engine, and the high-speed shaft of the planetary gearbox is drivenly connected to the front end of the rotor shaft of the generator. The auxiliary cooling fan is located at the rear end of the generator and is drivenly connected to the rear end of the rotor shaft. Diesel generator sets generally have poor noise reduction performance, and diesel generator sets generate a lot of noise when they are working, which seriously affects the lives of people in the surrounding area.

[0004] Chinese Patent Application No. 201610960104.6 discloses a mobile diesel generator set, comprising a fuel tank, a depressurization valve, a special shock-absorbing device, and a generator. The key feature is that a depressurization valve is fixedly installed on one side of the fuel tank, and the fuel tank is connected to the generator via a connecting cable. The generator is equipped with a control switch, with an oil port on one side and a pull plate on the other side. The generator is fixedly connected to the special shock-absorbing device via a bracket. Existing diesel generator sets are bulky, inconvenient to move, and unstable during use, affecting normal operation. They also lack a purification mechanism, causing pollution to the surrounding environment from the diesel fuel emitted during operation.

[0005] The existing temporary power supply uses diesel or gasoline generator sets, which are noisy and unsuitable for venues with high noise requirements, such as concerts and filming. They also have long start-up times, limited emergency response speed, and the fumes emitted during operation can pollute the surrounding environment. Summary of the Invention
