Abstract

The invention relates to a storage battery charging and jointly outputting system of a current-limiting power supply. In the invention, an engine generator or a mains alternating current power supply is used, and the system specifically has the characteristic of limiting the maximum output current via an electromagnetic effect and / or has the characteristic of setting constant current lower than the maximum output current or setting an output close to the constant current so as to supply power to a load and charge a storage battery or supply power to the load together with the storage battery; and when an engine generator set is used as a power supply, during running, the engine runs with an optimal and / or better energy-saving revolution in an optimal and / or better torque region in the Brake Specific Fuel Consumption.

Description

technical field

[0001] The invention relates to storage battery (storage battery or storage battery for short) technology, in particular to a storage battery charging and cooperative output system of a current-limited power supply. Background technique

[0002] Due to its portability and practical capacity, storage batteries are often used as emergency power supplies, electric vehicles and electric tools, or as DC power supply devices. The battery will increase the cost and weight, or make the battery pack work at a deeper discharge depth and affect the life of the battery; the inventor's original authorized patent No. 02149231.X discloses an engine-driven battery auxiliary charging system that automatically monitors the operation , in order to use the engine generator as an auxiliary power source for driving load motors (or other loads) and to carry out timely auxiliary charging for stationary or vehicle-mounted storage batteries, so as to keep the storage batteries in a go...
