Abstract: A system for tracking a location of a movable object can include a tracking device mounted to a collar. The tracking device can be configured to track its location using at least one of a global positioning system signal, a Bluetooth signal, and a Wi-Fi signal. The system can include a middle man charging mechanism. The middle man charging mechanism can be configured to receive electrical energy from a base station charging device. The middle man charging mechanism can be configured to store the received electrical energy. The middle man charging mechanism can be configured to couple to an external charging interface of the tracking device to recharge the battery included in the tracking device while the collar is worn by the movable object. The tracking device can also be configured to transmit information corresponding to the location of the tracking device to an external computing device.
