Abstract

La presente descripción se relaciona con un aparato de detección de voltaje, una batería y un método de detección de voltaje. El aparato de detección de voltaje incluye: un módulo de detección de voltaje y una línea de circuito; en el cual un segmento de la línea de circuito está configurada como un resistor de línea, y terminales de detección del módulo de detección de voltaje están conectados a terminales del resistor de línea a través de líneas de medición, respectivamente. El aparato de detección de voltaje proporcionado por modalidades de la presente descripción, mediante la configuración del segmento de la línea de circuito como el resistor de línea, permite justamente que el módulo de detección de voltaje detecte el voltaje sobre el resistor de línea. Dado que el resistor de línea es parte de la línea de circuito, su resistencia no cambiará mucho con cambios de voltaje y temperatura, por lo que el resistor de línea tiene buena estabilidad y por lo tanto la detección de voltaje es precisa.
