Title:
BATTERY SAFETY DEVICE AND METHOD OF AUTOMATICALLY CONTROLLING BATTERY SECURITY
Document Type and Number:
Japanese Patent JPS609337
Kind Code:
A
Abstract:
A method and apparatus is disclosed for automatic control of battery maintenance including fast recharge and equalizing of the voltages on individual cells of the battery. The charging current through a resistance in series with the battery is monitored, and in response, a control circuit energizes a relay which controls the output voltage of a power supply used to charge the battery and drive a load. The control circuit includes a clock, connected to a recharge counter, which effects the recharge process for a predetermined period of time. The recharge counter is connected to the relay which regulates the output voltage of the power supply. The control circuit also includes a battery current sensor, which monitors the charging current of the battery, and a second counter, which provides an enabling signal to the relay for initiating a longer cycle which equalizes the charges on individual cells of the battery if the battery has been recharged from a severely discharge state.
