Battery charging apparatus

摘要

A battery charging and analyzing apparatus for a nickel-cadmium battery is disclosed. The equipment utilizes a type of solid state resistor formed of a plurality of paralleled emitter follower transistors which are collectively a load for a Ni-Cid battery. The apparatus senses the requirements for charge and adjusts a control voltage which is compared with a reference voltage. The control voltage is applied to a circuit which conditions a signal to adjust the conductivity of the emitter follower transistors as required. When the device is switched on or off by the application of power, charging or discharging through the solid state resistor (SSR) is accomplished. This is accomplished over a timed interval.
