Large charger in the process of Charging, if will be full of after interrupt Charging current, or let it will in the internal battery overcharge of reactions such as gas, water loss and temperature rise; Long time overcharge will directly affect the service life of the high power charger. So, as far as possible in order to prolong the service life of charger, charging condition of large charger must be notice, common control methods include the following:
The first is a timing control with constant current Charging method, battery Charging time required is based on battery capacity and Charging easily determine the size of the current, so just set in advance good Charging time, wait for your time, punctuality device will automatically release signal to stop Charging; This method is simple, but the charging time is not on the basis of battery contains power condition automatic adjustment, so the actual charging, there may be charging charging less than, or the phenomenon of excessive.
Another kind is judged according to the battery temperature is full of; Normal charging, the temperature of the battery change is not obvious, once the charging excessive, the internal gas pressure will increase rapidly, oxidation reaction on the negative plate to make internal fever, temperature rising fast. Therefore, large temperature change of the battery charger investigation, can distinguish the battery charging status. Usually choose two thermistor separation test battery temperature and environmental temperature, when the temperature reached a certain value, can stop charging.
