Electrical energy increasing device

Abstract

The invention discloses an electrical energy increasing device, which is used together with a rechargeable battery serving as a power source of the electrical energy increasing device. The electrical energy increasing device comprises an energy storage circuit, an electrical energy increasing circuit, an oscillation circuit, a booster circuit and a rectification filter circuit. The energy storage circuit is connected in parallel with the rechargeable battery. The electrical energy increasing circuit comprises at least one group of magnetic core coil and a rectification circuit electrically connected with the output ends of the magnetic core coil of each group respectively. The input end of a primary coil of the first group of magnetic core coil is electrically connected with the cathode of the rechargeable battery. The output end of the rectification circuit is electrically connected in parallel with the energy storage circuit. The input end of the oscillation circuit is electrically connected with the output end of a primary coil of the last group of the electrical energy increasing circuit. The input end of the booster circuit is electrically connected with the output end of the oscillation circuit. The input end of the rectification filter circuit is electrically connected with the output end of the booster circuit, and the output end of the rectification filter circuit is electrically connected with the rechargeable battery. The electrical energy increasing device has a simple structure and a small volume, and can realize the self-charging of the rechargeable battery.

Description

technical field [0001] The invention relates to a charging device for a rechargeable battery. Background technique [0002] With the increasingly tense global energy situation, more and more countries in the world pay more and more attention to energy conservation and environmental protection. A battery, also known as a secondary battery, is an electrical device that stores electrical energy in the form of chemical energy and converts chemical energy into electrical energy. [0003] Batteries are important electrical components. The service life of existing accumulators is relatively short, like the accumulators used in electric vehicles, the service life is only about a few years. Moreover, the storage battery also has high requirements in terms of maintenance and maintenance. If the maintenance is not done properly, the storage battery is easily damaged, and the service life is greatly shortened, thereby increasing the user's use cost, and the used storage battery is eas...

The service life of the existing batteries is relatively short, like the batteries used in electric vehicles, the service life is only about a few years

Moreover, the storage battery also has high requirements in terms of maintenance and maintenance. If the maintenance is not done properly, the storage battery is easily damaged, and the service life is greatly shortened, thereby increasing the user's use cost, and the used storage battery is easy to pollute the environment.
