CHARGE-DISCHARGE CONTROLLING APPARATUS FOR BATTERY IN COMMERCIAL MULIT-STAGE RICE COOKER

摘要

PURPOSE: A storage battery charging/discharging control device of multistage jar for business use is provided to extend the lifetime of the storage battery by maintaining the battery in optimal state. CONSTITUTION: An alternating current detecting part(3) is connected to a secondary side coil of transformer in order to detect the supply state of AC voltage. A relay(4) is turned on/off according to the output signal of a relay driving part which is controlled by the MICOM(7). The relay controls the electric charging/discharging operation of the storage battery(2). The relay driving part controls the relay according to the control of the MICOM. A storage battery voltage detecting portion(6) detects the output voltage of the storage battery through a contact switch(S) of the relay. The MICOM supplies automatically the voltage charged in the storage battery to load(8) in the state that AC power source is cut off.
