Abstract
A pulse controlled charging method for higher temperature charging in addition to the current-reducing operation at ambient temperature. A specific software control strategy for these purposes is proposed, which can be divided into two parts, (a) two-stage charging current control at ambient temperature, which sets different current-limiting transient points for chargers with different outputs; (b) high-temperature pulse charging, which utilizes an internal NTC (Negative temperature coefficient) thermistor inside the charger to detect the internal temperature of the charger, if the temperature exceeds a pre-determined value, the charging process will be stopped for a period of time to avoid the temperature of the charger becoming too high.
