The post details a simple automatic High Voltage Battery Charger Circuit which can be used for an automatic charging control of any preferred high voltage battery bank such as a 360V battery bank. The idea was requested by "resonance". I found all your circuit and projects interesting but please I need a special assistance.
The shown high current battery charger circuit is a smart way of charging a battery and also achieving an auto shut off when the battery attains a full charge level. The circuit is actually a simple common collector transistor stage using the shown 2N6292 power device.
In the shown high current battery charger circuit using a voltage regulator, the base of the transistor is fed with a regulated 15 V from the IC 7815, which ensures a potential difference of about 15 - 0.7 = 14.3 V across the emitter/ground of the transistor.
For example, if your battery is rated at 12 V, 100 Ah, then the fixed input voltage should be 17% higher than the printed value, that's equal to around 14.1 V ( not 14.40 V, unless you are using a step charger). Current (ampere) ideally should be 1/10th of the Ah level printed on the battery, so in our case this can be 10 amperes.
Charging will begin after the battery voltage rises above 35% (typical) of the Stage 2 voltage limit. If the battery voltage subsequently falls below 31% (typical), charging will again stop and the fault will be indicated on the FAULT and STATUS pins. The maximum charging current is configured with the output current limiting circuit.
A high voltage power supply can be used to provide higher common mode voltage. A current meter (AM1) is used to measure actual current flowing through shunt resistor.
