Abstract

PURPOSE:To obtain a charging equipment for enabling the residual battery capacity of a charging battery to be confirmed, by providing a loading means for loading to the charging battery for a fixed time. CONSTITUTION:A charging circuit 1 for charging a charging battery with low tension alarm function, with an external power source or a built-in power source 3 is set. Besides, a loading circuit 7 for enabling a load to be applied to the charging battery for a fixed time is contrived to be set. The loading circuit 7 includes, for example, a variable resistor 8 for setting load current and a transistor 11, and is composed to take load power out of the charging battery, just during pulse at fixed intervals generated from a pulse generating circuit 4. As a result, the residual capacity of the charging battery can be confirmed through the value of the load current taken out with the loading circuit 7, and a charging capacity can be previously prevented from being zero during the using.
