Abstract

A (delta)P charging device consists of direct current, D.C. voltage adjusting circuit, (delta)V circuit, (delta)i circuit, (delta)t circuit, protect circuit and battery, in which (1) direct current can utilize direct current voltage or direct current pulse voltage with sinusoid function as charging power; (2) direct current voltage adjusting circuit used for adjusting direct current voltage to the voltage needed by charged battery; (3) (delta)V circuit is based on (delta)V value written on the manual of charged battery, then becomes equivalent (delta)V circuit of detected battery; (4) (delta)i circuit is based on (delta)i value written on the manual of charged battery, then becomes equivalent (delta)i circuit of detected battery; (5) (delta)t circuit is based on (delta)t value written on the manual of charged battery, then becomes equivalent (delta)t circuit of detected battery; (6) the contact point of protect circuit is completely insulated on one side when charged battery is not installed in. After the battery is installed, by battery remaining electric energy the photocoupler is enabled to make relay be in normal close state, and the charged battery is connected to the (delta)P charging device, if the charged battering is in state of no voltage, then it could enter charging state by press-fit switch; (7) when the charged battery enters into saturation state, another side of protect circuit detects either one of (delta)V circuit, (delta)i circuit and (delta)t circuit, then the charging voltage disappears immediately, and there is one indicator lamp indicating saturation state; (8) the (delta)P charging device is suitable to charge any rechargeable battery.
