BATTERY-BASED CHARGING EQUIPMENT, BATTERY-BASED CHARGING SYSTEMS, AND HIGH-CURRENT LITHIUM-ION BATTERIES

Abstract

The invention proposes a charging system, a charging device of the type of power supply, and a high-current lithium-ion battery charger that is capable of being reduced in size with a simple structure, and allows for further reduction in charging time to charge high-current lithium-ion batteries with a charging capacity sufficient to power electrical equipment. The charging device of the type of power supply comprises a charging connector, an integrated high-current lithium-ion battery satisfying the high-current discharge parameters, a compatible battery detector and switch, and a high-current current supply path. The compatible battery detector and switch are arranged within the high-current current supply path.The structure is designed to switch to the "OFF" state in response to the detection that lithium-ion batteries with high current charging, satisfying the maximum operating voltage and high current charging parameters, are connected to the charging connector, allowing high current to be supplied from the integrated lithium-ion battery with high current through the high current supply line without any intervention from the voltage converter, so the lithium-ion battery with high current charging is charged with high current. High current refers to the current corresponding to a rate of 10°C or more for a charging capacity of 2.5Ah.
