Abstract:
1. A charging system for a battery, comprising: a charging circuit coupled to at least one battery maintained in a housing, the charging circuit configured to charge the at least one battery; a sensor configured to measure a temperature of the at least one battery; a fan arranged relative to the housing for creating airflow through the housing to cool the at least one battery; and a module configured to receive temperature measurements from the sensor, to determine whether a received temperature measurement exceed a temperature threshold, to vary a speed of the fan based on the temperature measurements, and to regulate the charging circuit to increase or decrease a charge rate of the at least one battery as a function of the fan speed; wherein, whenever it is determined that the received temperature measurements do not exceed a temperature threshold, the module decreases the fan speed and increases the charge rate.
