The invention discloses a method and system for intelligently charging a starting battery of an electric vehicle, and relates to the technical field of battery charging. The method comprises the step that an intelligent charging mode is determined; if a voltage detection mode is selected, when the voltage of the starting battery is smaller than the voltage lower limit value, the temperature of the starting battery is detected in real time, a corresponding charging process is entered according to the temperature, and when the voltage of the battery is larger than the voltage upper limit value, charging of the battery is stopped; if a timed wake-up mode is selected, when the set sleep time is reached and the voltage of the starting battery is smaller than the set voltage upper limit value, the step of detecting the temperature of the starting battery in real time is executed, and otherwise, the system enters sleep; and if an automatic detection mode is selected, the next charging time before the system is dormant is calculated, and when the charging time is reached, the step of detecting the temperature of the starting battery in real time is executed. According to the method, the environment temperature for starting the battery is adjusted to ensure that the battery is at the optimal charging temperature, and the service life and standing time of the battery are prolonged.

    本发明公开了一种电动车辆启动电池智能充电的方法及系统,涉及电池充电技术领域,该方法包括确定智能充电模式;若选择电压检测模式,当启动电池的电压小于电压下限值时,实时检测启动电池的温度,并根据温度进入相应的充电流程,当电池电压大于电压上限值时,停止给电池充电;若选择定时唤醒模式,当到达设定的休眠时间时,当启动电池的电压小于设定的电压上限值时,执行实时检测启动电池的温度的步骤,否则系统进入休眠;若选择自动检测模式,则在系统休眠前计算出下次要进行充电的时间,当到达充电时间时,执行实时检测启动电池的温度的步骤。该方法通过对启动电池的环境温度进行调节,保证电池处于最佳充电温度,延长了电池寿命和静置时间。
