This work has fabricated a control module to assist a cooling device to be used in an electric car. Using the solar power, the module is responsible for recharging the battery, activating the fans, and monitoring the cabin temperature. The module relies on an analog amplifier and notifies the car users of its operation status. The subject of study is the UXV-500 of KYMCO. Its cabin is currently an open space, but is very likely to become an enclosure.
