Abstract

Se proporciona un circuito de activación de baterías y un circuito de fugas de la batería; el circuito de activación de batería incluye un primer paquete de baterías y un segundo paquete de baterías conectados en serie y un primer interruptor conectado al primer paquete de baterías a lo largo de una primera trayectoria de corriente; un controlador electrónico acoplado a y que controla el primer interruptor se configura para detectar un accionamiento por disparo y cerrar el primer interruptor con base en la detección del accionamiento por disparo para extraer una corriente de activación en la primera trayectoria de corriente desde el primer paquete de baterías; el controlador electrónico también se configura para controlar un motor para extraer una corriente de carga a lo largo de una segunda trayectoria de corriente después de que se activa el primer paquete de baterías; el circuito de fugas de la batería también incluye un interruptor conectado en serie con el capacitor y un interruptor del gatillo que controla el interruptor de manera que el interruptor evita un flujo de corriente de fuga a través del capacitar cuando el gatillo no se acciona.
