Abstract
A motor driven industrial actuator device includes an enclosure that houses: a motor, a control module, a drive, a battery pack and associated temperature sensor, and an input that receives an external power supply. The control module receives: the status of the external power supply, the charge state of the battery pack, the status of the battery pack, or the charge state and status of the battery pack. The control module causes the battery pack to be charged when an external power supply is present and the battery pack requires charging. During charging of the battery pack, the control module: receives the temperature associated with the battery pack from the temperature sensor; compares the measured temperature with a predetermined threshold temperature; and reduces the current to the battery pack if the measured temperature is greater than the predetermined threshold temperature.
