The invention relates to the field of instrument display, and provides a hydrogen energy heavy truck charging state information display method and system.The method comprises the steps that if a VCU detects that a charging gun is inserted into a charging port, the VCU awakens an instrument through a hard wire; the VCU detects whether the hydrogen energy heavy truck is powered off or not; if the hydrogen energy heavy truck is not powered off, charging operation of the hydrogen energy heavy truck is forbidden, and the instrument prompts that the hydrogen energy heavy truck needs to be powered off; if the hydrogen energy heavy truck is powered off, the vehicle control unit VCU detects the state of a charging gun to obtain charging information, and the charging information is transmitted to the instrument through the gateway to be displayed; and after a preset time T, the VCU stops detecting the state of the charging gun, and the instrument is automatically extinguished and enters a dormant state. During charging, the instrument is automatically turned off after displaying charging information for a period of time, so that the service life of the instrument is prolonged while electric energy is saved; and various charging information checking schemes are provided, so that the charging information can be checked after the instrument is extinguished.

    本发明涉及仪表显示领域,提供一种氢能重卡充电状态信息显示方法及系统,包括步骤:若整车控制器VCU检测到充电枪插入充电口,则整车控制器VCU通过硬线唤醒仪表;整车控制器VCU检测氢能重卡是否下电;若氢能重卡没有下电,则禁止氢能重卡进行充电操作,仪表提示氢能重卡需要下电;若氢能重卡已经下电,则整车控制器VCU检测充电枪的状态,获得充电信息,通过网关将充电信息传输至仪表进行显示;经过预设时间T后,整车控制器VCU停止检测充电枪的状态,仪表自动熄灭并进入休眠状态。本发明中充电时,仪表显示一段时间的充电信息后自动关闭,节约电能的同时延长仪表的使用寿命;提供多种充电信息的查看方案,保证在仪表熄灭后也能查看充电信息。
