Power-storage-type charging apparatus, power-storage-type charging system, and high-current chargeable driving lithium-ion battery

Abstract

Provided are a charging system, an electricity storage-type charging device, and a high-current chargeable driving lithium-ion battery with which it is possible to achieve size reduction using a simple configuration and to further reduce the charging time of a high-current chargeable driving lithium-ion battery having a charging capacity that can drive an electronic device. The electricity storage-type charging device comprises: a charge object connection unit; a high-current dischargeable built-in lithium-ion battery satisfying a high-current discharging specification; a compatible battery detection / switching unit; and a highcurrent passable current output path. The compatible battery detection / switching unit is provided in the highcurrent passable current output path. When detecting connection of a high-current chargeable driving lithiumion battery satisfying an in-use maximum voltage specification and a high-current charging specification to the charge object connection unit, the compatible battery detection / switching unit turns on to allow a high current to pass through the high-current passable current output path without the intervention of a voltage converter so that the high-current chargeable driving lithium-ion battery can be charged with a high current output from the high-current dischargeable built-in lithium-ion battery. The high current is a current corresponding to a rate of 10 C or higher with respect to a charging capacity of 2.5 Ah.
