在现有的卡车中，卡车配置有两套空调系统。其中，一套空调系统包括车载整体空调器，其由发动机驱动，以便在行车过程中对驾驶室内的环境温度进行调节；另一套空调系统包括驻车空调器，其由卡车上的车辆电池供电，在卡车处于驻车状态下，发动机处于怠速状态或者熄火状态，此时通过驻车空调器对驾驶室内的环境温度进行调节。下面结合驻车空调器来对本发明的车辆电池的寿命预警方法进行介绍。In the existing trucks, the truck is equipped with two air conditioning systems. Among them, one air-conditioning system includes a vehicle-mounted integral air conditioner, which is driven by an engine to adjust the ambient temperature in the cab during driving; the other air-conditioning system includes a parking air conditioner, which is powered by the vehicle battery on the truck , When the truck is in the parking state and the engine is in the idling state or off state, the ambient temperature in the cab is adjusted by the parking air conditioner. In the following, the vehicle battery life warning method of the present invention will be introduced in conjunction with a parking air conditioner.
卡车上的车辆电池用于向驻车空调器、点火装置、照明装置等用电设备供电。在驻车空调器的使用过程中，实时检测车辆电池的输出电压，当车辆电池的输出电压处于第一电压值时开始计时，随着车辆电池持续供电，当车辆电池的输出电压降至第二电压值时，结束计时，同时记录该过程中的实时电流值和实时电压值，经过处理后得到电压、电流与时间的关系曲线，积分计算后获得车辆电池的输出电压从第一电压值降至第二电压值所消耗的第一电量，然后比较第一电量与基准电量的大小。若第一电量小于基准电量，则发出预警信息提示用户车辆电池的寿命缩短到一定的程度，以便用户及时对车辆电池进行相应的处理。若第一电量大于等于基准电量，则不发送预警信息或者发送车辆电池寿命正常的信息。The vehicle battery on the truck is used to power the parking air conditioner, ignition device, lighting device and other electrical equipment. During the use of the parking air conditioner, the output voltage of the vehicle battery is detected in real time, and the timing starts when the output voltage of the vehicle battery is at the first voltage value. As the vehicle battery continues to supply power, when the output voltage of the vehicle battery drops to the second When the voltage value, the timing ends, and the real-time current value and real-time voltage value in the process are recorded at the same time. After processing, the relationship curve between voltage, current and time is obtained. After the integral calculation, the output voltage of the vehicle battery is reduced from the first voltage value. The first power consumed by the second voltage value is then compared with the size of the reference power. If the first power level is less than the reference power level, an early warning message is issued to remind the user that the life of the vehicle battery is shortened to a certain extent, so that the user can handle the vehicle battery in time. If the first power is greater than or equal to the reference power, no warning message is sent or a message that the vehicle battery life is normal is sent.
在车辆电池处于预定状态的情形下，如在驻车空调器首次使用的过程中，实时检测车辆电池的输出电压，当车辆电池的输出电压处于第一电压值时开始计时，随着车辆电池的持续供电，当车辆电池的输出电压降至第二电压值时，结束计时，同时记录该过程中的实时电流值和实时电压值，经过处理后得到电压、电流与时间的关系曲线，积分计算后获得车辆电池的输出电压从第一电压值降至第二电压值所消耗的第二电量，第二电量乘以预设系数得出基准电量。优选地，在驻车空调器前n(n＝2、3、4…)次使用的过程中，获取n个第二电量，计算n个第二电量的平均值并乘以预设系数得出基准电量。虽然在获取第一电量的过程中，可能存在车辆电池向其他用电设备供电的情况，但是驻车空调器的功率较大，其他用电设备用电量对获取的第一电量的影响不大，可以忽略不计。When the vehicle battery is in a predetermined state, such as during the first use of the parking air conditioner, the output voltage of the vehicle battery is detected in real time, and the timing starts when the output voltage of the vehicle battery is at the first voltage value. Continuous power supply. When the output voltage of the vehicle battery drops to the second voltage value, the timing ends, and the real-time current value and real-time voltage value during the process are recorded at the same time. After processing, the relationship curve between voltage, current and time is obtained. After the integral calculation Obtain the second power consumed when the output voltage of the vehicle battery drops from the first voltage value to the second voltage value, and multiply the second power by the preset coefficient to obtain the reference power. Preferably, during the first n (n=2, 3, 4...) uses of the parking air conditioner, n second electric quantities are obtained, and the average value of n second electric quantities is calculated and multiplied by a preset coefficient to obtain Baseline power. Although there may be situations in which the vehicle battery supplies power to other electrical equipment during the process of obtaining the first power, the power of the parking air conditioner is relatively large, and the power consumption of other electrical equipment has little effect on the obtained first power , Can be ignored.
在车辆电池最初前n(n＝2、3、4…)次使用的过程中，获取n个第二电量的电量值，计算n个第二电量的平均值并乘以预设比例系数得出基准电量，能够减小误差，提高了基准电量的准确性，从而提高了车辆电车的寿命预警的准确性。During the first n (n=2, 3, 4...) use of the vehicle battery, obtain the power value of n second power levels, calculate the average value of n second power levels and multiply it by the preset scale factor to get The reference power can reduce the error and improve the accuracy of the reference power, thereby improving the accuracy of the life warning of the vehicle tram.

In addition, the first electric quantity and the second electric quantity obtained by detecting the relationship between voltage, current and time and integrating are only an exemplary description. Those skilled in the art can understand that the first electric quantity and the second electric quantity can also be obtained through Measured by the energy meter.

本领域技术人员可以理解的是，基准电量包括第一基准电量和第二基准电量、预警信息包括第一预警信息和第二预警信息，仅是一种具体的实施方式，本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，如基准电量可以包括三个或者三个以上的不同的基准电量，预警信息包括相应数量的不同预警信息，具体地，如基准电量包括基准电量一、基准电量二、基准电量三，预警信息包括第一预警信息、第二预警信息、第三预警信息，第一预警信息为能够使用户获知并简单维护车辆电池的信息，第二预警信息为能够使用户获知并专业维护车辆电池的信息，第三预警信息为能够使用户获知并更换车辆电池的信息。当第一电量大于等于基准电量一时，不发出预警信息；当第一电量小于基准电量一并且大于等于基准电量二时，发出第一预警信息，以便用户及时对车辆电池进行简单维护，如清理车辆电池电极柱上的污垢、添加蒸馏水等；当第一电量小于基准电量二并且大于等于基准电量三时，发出第二预警信息，以便用户及时将车辆电池送至专业维护地点进行专业维护；当第一电量小于基准电量三时，发出第三预警信息，以便用户及时更换车辆电池。Those skilled in the art can understand that the reference power includes the first reference power and the second reference power, and the early warning information includes the first early warning information and the second early warning information. This is only a specific implementation, and those skilled in the art can follow It needs to be adjusted to suit specific applications. For example, the reference power level can include three or more different reference power levels, and the warning information includes a corresponding number of different warning information. Specifically, if the reference power level includes the reference power level one , Reference power level 2, Reference power level 3, the warning information includes the first warning information, the second warning information, and the third warning information.

优选地，在第一电压值为车辆电池在满电状态下的电压，并且第二电压值为车辆电池的点火保护电压。由于车辆电池在使用过程中电压值的变化范围不大，通过上述的设置，测量的第一电压和第二电压之间的差值相对较大，能够较为准确地测出第一电压值和第二电压值，获取更接近实际值的第一电量，从而进一步提高寿命预警的准确性。Preferably, the first voltage value is the voltage of the vehicle battery in a fully charged state, and the second voltage value is the ignition protection voltage of the vehicle battery. Since the voltage value of the vehicle battery has a small change range during use, through the above setting, the difference between the measured first voltage and the second voltage is relatively large, and the first voltage value and the second voltage can be measured more accurately. The second voltage value is used to obtain the first electric quantity that is closer to the actual value, thereby further improving the accuracy of the life warning.
本领域技术人员可以理解的是，上述设置仅是一种优选的实施方式，本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，如第一电压值为车辆电池在满电状态下的电压，第二电压值为点火保护电压与满电状态下的电压之间的任一个电压；也可以是第一电压值为点火保护电压与满电状态下的电压之间的任一个电压，第二电压值为点火保护电压；还可以是第一电压值、第二电压值为点火保护电压与满电状态下的电压之间的两个不同的电压。Those skilled in the art can understand that the above setting is only a preferred embodiment, and those skilled in the art can adjust it as needed to adapt to specific applications.
