The invention relates to a method for protecting a standby battery of a vehicle-mounted terminal, the vehicle-mounted terminal comprises a power supply circuit connected with a power output circuit of a vehicle and a charging circuit connected with the power output circuit and the standby battery, and the method comprises the following steps: S1, detecting the current state of the vehicle, and supplying power to the vehicle-mounted terminal through the power supply circuit when the vehicle is in a starting state; s2, monitoring the first current electric quantity of the standby battery, judging whether the first current electric quantity is smaller than a first preset value or not, if yes, executing the step S3, and if not, executing the step S4; s3, starting a charging circuit to charge the standby battery, and executing the step S4 when the standby battery is charged; and S4, turning off the charging circuit. By implementing the invention, the service life of the standby battery can be greatly prolonged.

    本发明涉及一种车载终端备用电池保护方法,车载终端中包括:连接车辆的电源输出电路的供电电路和连接电源输出电路与备用电池的充电电路,方法包括:S1、检测车辆的当前状态,在车辆为启动状态时通过供电电路对车载终端供电;S2、监测备用电池的第一当前电量,判断第一当前电量是否小于第一预设值,若是,则执行步骤S3,否则执行步骤S4;S3、开启充电电路以对备用电池进行充电,并在备用电池完成充电时执行步骤S4;S4、关断充电电路。实施本发明能大大提高备用电池的使用寿命。
