Based on the dual output DC conversion unit 102, when the power battery 202 and the startup power battery 201 are charged, there are two different modes: a switching charging mode and a parallel charging mode. For the switching charging mode, there is only one output at the same time, that is, charging the power source battery 201 or charging the power battery 202 at the same time. When the power source battery 201 is powered off, the power source battery 201 is preferentially charged to ensure that the vehicle does not fail to start due to power failure of the power source battery 201. For the parallel charging mode, both the power source battery 201 and the power battery 202 can be charged at the same time.

四、车辆太阳能充电控制方法Fourth, vehicle solar charging control method
本发明提出的一种车辆太阳能充电控制方法，该方法为：检测车辆启动电源电池的剩余电量；当所检测到车辆启动电源电池的剩余电量小于设定阈值时，通过太阳能电池组件与直流变换单元，利用太阳能对车辆启动电源电池进行充电。The invention provides a solar energy charging control method for a vehicle, which is: detecting a remaining power of a vehicle starting a power source battery; and when detecting that a remaining power of the vehicle starting power source battery is less than a set threshold, the solar cell module and the DC conversion unit are Use the solar energy to charge the vehicle's starting power battery.
本实施例的车辆太阳能充电控制方法包括车辆太阳能充电装置启动时的检测控制方法、工态下的检测控制方法。The vehicle solar charging control method of the present embodiment includes a detection control method when the vehicle solar charging device is started, and a detection control method under the working state.

对于改进后的车辆太阳能充电装置，可以工作于切换充电模式，对车辆启动电源电池和动力电池切换充电，此时需要设定车辆启动电源电池充电的优先级高于车辆动力电池充电的优先级。当车辆太阳能充电装置在启动时，首先检测启动电源电池的电压是否小于预设的第一阈值(充电截止电压)，以保证优先给启动电源电池充电到充电截止电压。以后就切换到对动力电池进行充电，在这个过程中，如果启动电源电池又慢慢亏电了，车主想开车，却发现无法启动。为了避免这种情况发生，就要每隔一定时间检测一下启动电源电池上的电压是否低于预设的第二阈值(放电截止电压)，如果低的话，就要及时切换到对启动电源电池进行充电。For the improved vehicle solar charging device, it can work in the switching charging mode to switch and charge the vehicle starting power battery and the power battery. At this time, it is necessary to set the priority of the vehicle starting power battery charging to be higher than the vehicle power battery charging priority. When the vehicle solar charging device is started, it is first detected whether the voltage of the starting power battery is less than a preset first threshold (charge cutoff voltage) to ensure that the starting power battery is preferentially charged to the charging cutoff voltage. Later, I switched to charging the power battery. In the process, if the power supply battery was slowly depleted, the owner wanted to drive, but found that it could not be started. In order to avoid this, it is necessary to check at a certain time whether the voltage on the starting power battery is lower than the preset second threshold (discharge cutoff voltage). If it is low, it is necessary to switch to the starting power battery in time. Charging.
