The system includes a first mechanism for receiving a feedback signal and providing a charging signal to the battery over a first electrical path when the feedback signal indicates that the battery is not fully charged. A second mechanism measures a voltage state of the battery via second and third electrical paths and provides the voltage state as the feedback signal to the first mechanism in response thereto. In the specific embodiment, the first mechanism is a controllable power supply and the second mechanism is a sensing circuit. The sensing circuit includes a subtractor circuit that subtracts the voltage on the second electrical path from the voltage on the third electrical path and provides the feedback signal in response thereto. The second electrical path includes a wire connected between a first terminal of the subtractor circuit and a positive terminal of the battery. El sistema incluye un primer mecanismo para recibir una senal de retroalimentacion y proporcionar una senal de carga a la bateria sobre una primera trayectoria electrica cuando la senal de retroalimentacion indica que la bateria no esta completamente cargada. Un segundo mecanismo mide un estado de voltaje de la bateria via segunda y tercera trayectorias electricas y proporciona el estado de voltaje como senal de retroalimentacion al primer mecanismo en respuesta a esto. En la modalidad especifica, el primer mecanismo, es un suministro de energia controlable y el segundo mecanismo es un circuito de deteccion. El circuito de deteccion incluye un circuito sustractor que sustrae el voltaje sobre la segunda trayectoria electrica del voltaje sobre la tercera trayectoria electrica y proporciona la senal de retroalimentacion en respuesta a esto. La segunda trayectoria electrica incluye un alambre conectado entre una primera terminal del circuito sustractor y una terminal positiva de la bateria.
