本发明实施例涉及车辆技术领域，并且更具体地，涉及一种电源***、车辆以及用于控制车辆的电源***的方法和装置。Embodiments of the present invention relate to the field of vehicle technology, and, more particularly, to a power supply system, a vehicle, and a method and apparatus for controlling a power supply system of a vehicle.
背景技术Background technique
与传统燃油汽车相比，新能源汽车(例如电动汽车，油电混合动力汽车)在行驶过程中废气排放较少或者可以达到零排放。因此，新能源汽车对环境造成的污染大大降低，这使得新能源汽车在近年来越来越受到关注，选择新能源汽车的用户也越来越多。Compared with traditional fuel vehicles, new energy vehicles (such as electric vehicles, hybrid electric vehicles) have less exhaust emissions or can achieve zero emissions during driving. Therefore, the pollution caused by new energy vehicles to the environment is greatly reduced, which makes new energy vehicles more and more concerned in recent years, and more and more users choose new energy vehicles.
虽然新能源汽车有污染小的优点，但是为新能源汽车提供动力的电池的容量是有限的，并且电池通常需要很长时间才能充满电，而且新能源汽车需要行驶到安装有充电桩的停车场或充电站才能完成充电。在一般情况下，用户在使用停车场的固定充电桩为新能源汽车充电时，除需要缴纳电费外，还需要额外缴纳停车费用，这提高了用户使用新能源汽车的成本。因此，电池的充电问题成为限制新能源汽车发展的一个瓶颈。Although new energy vehicles have the advantage of low pollution, the capacity of batteries that power new energy vehicles is limited, and batteries usually take a long time to fully charge, and new energy vehicles need to travel to parking lots with charging piles. Or the charging station can complete the charging. Under normal circumstances, when users use a fixed charging pile of a parking lot to charge a new energy vehicle, in addition to paying the electricity bill, an additional parking fee is required, which increases the cost of the user using the new energy vehicle. Therefore, the charging problem of the battery has become a bottleneck restricting the development of new energy vehicles.

When the user determines that the driving destination does not have a charging stake, the second battery system can be selected to power the vehicle to take the second battery system away from charging after reaching the destination.
在一些实施例中，控制装置103可以根据该第一电池***和/或该第二电池***的电量选择为该车辆提供动力的电池***。In some embodiments, control device 103 can select a battery system that powers the vehicle based on the amount of power of the first battery system and/or the second battery system.
例如，若该第一电池***的剩余电量低于第一预设阈值，而该第二电池***的剩余电量不低于第二预设阈值，则控制装置103可以控制该第二电池***为该车辆提供动力。该第一预设阈值和该第二预设阈值可以是电量值，也可以是剩余电量与充满电时的电量的比值。该第一预设阈值与该第二预设阈值可以是预设好的，也可以是用户输入的。该第一预设阈值可以与该第二预设阈值相 等，也可以是不等。For example, if the remaining battery capacity of the first battery system is lower than the first preset threshold, and the remaining power of the second battery system is not lower than the second preset threshold, the control device 103 may control the second battery system to be the The vehicle is powered. The first preset threshold and the second preset threshold may be a power value, or may be a ratio of the remaining power to the power at the time of full charge. The first preset threshold and the second preset threshold may be preset or may be input by a user. The first preset threshold may be related to the second preset threshold Etc., it can also be unequal.
再如，若第一电池***的剩余电量低于该第一预设阈值，第二电池***的剩余电量低于该第二预设阈值，则控制装置103可以控制该第二电池***为该车辆提供动力直至该第二电池***的剩余电量消耗完。For another example, if the remaining power of the first battery system is lower than the first preset threshold, and the remaining power of the second battery system is lower than the second preset threshold, the control device 103 may control the second battery system as the vehicle. Power is supplied until the remaining power of the second battery system is exhausted.
在一些实施例中，控制装置103可以根据路况信息选择为该车辆提供动力的电池***。该路况信息可以包括道路信息，例如车辆行驶的道路是上坡、下坡、高速路、市区道路或郊区道路等，也可以包括拥堵信息，例如，车辆行驶的道路非常拥堵、一般拥堵或畅通等，还可以包括道路颠簸情况，例如车辆行驶的道路非常颠簸、一般颠簸或平稳等。控制装置103可以利用传感器、卫星定位***、或者用户手动输入的方式获取该路况信息，本发明实施例不作具体限定。控制装置103可以在路况信息不同的情况下，选择不同的电池***为该车辆提供动力。例如，若路况信息复杂(例如，道路颠簸)，则控制装置103可以选择该第一电池***和该第二电池***同时为该车辆提供动力。若路况信息很好(例如畅通的市区道路)，则控制装置103可以选择该第一电池***或该第二电池***为该车辆提供动力。In some embodiments, control device 103 can select a battery system that powers the vehicle based on the road condition information. The road condition information may include road information, for example, the road on which the vehicle travels is an uphill, downhill, highway, urban road or suburban road, etc., and may also include congestion information, for example, the road on which the vehicle travels is very congested, generally congested or unblocked. Etc., it can also include road bumps, such as the roads on which the vehicle travels are very bumpy, generally bumpy or smooth. The control device 103 can obtain the road condition information by using a sensor, a satellite positioning system, or a manual input by a user, which is not specifically limited in the embodiment of the present invention. The control device 103 can select a different battery system to power the vehicle if the road condition information is different. For example, if the road condition information is complex (eg, road bumps), the control device 103 can select the first battery system and the second battery system to simultaneously power the vehicle. If the road condition information is good (eg, an unobstructed urban road), the control device 103 can select the first battery system or the second battery system to power the vehicle.
在一些实施例中，控制装置103可以根据行车路线选择为该车辆提供动力的电池***。例如，假设用户的目的地为第一地点时，用户通常会选择第一电池***为该车辆提供动力。这样，若控制装置103根据行车路线确定出行程终点为该第一地点，则可以自动控制使用该第一电池***为该车辆提供动力。在此情况下，用户无需手动输入期望使用的电池***。In some embodiments, control device 103 may select a battery system that powers the vehicle based on the driving route. For example, assuming that the user's destination is the first location, the user typically selects the first battery system to power the vehicle. Thus, if the control device 103 determines that the end of the trip is the first location based on the driving route, the first battery system can be automatically controlled to provide power to the vehicle. In this case, the user does not need to manually enter the desired battery system.
在一些实施例中，控制装置103可以根据历史统计信息选择为该车辆提供动力的电池***。例如，控制装置103通过一段时间的统计，确定用户在工作日上午7点半至9点使用车辆时，选择第一电池***为该车辆提供动力的频率大于一个预设频率，而在工作日下午6点至8点时，选择使用该第二电池***为该车辆提供动力的频率大于一个预设频率。那么，控制装置103可以在工作日上午7点半至9点时，自动选择第一电池***为该车辆提供动力，在工作日下午6点至8点时，自动选择该第二电池***为该车辆提供动力。In some embodiments, control device 103 can select a battery system that powers the vehicle based on historical statistical information. For example, the control device 103 determines, by using a period of time statistics, that when the user uses the vehicle from 7:30 am to 9:00 am on the working day, the frequency at which the first battery system is selected to power the vehicle is greater than a preset frequency, and on the working day afternoon. From 6 o'clock to 8 o'clock, the frequency at which the second battery system is used to power the vehicle is selected to be greater than a predetermined frequency. Then, the control device 103 can automatically select the first battery system to power the vehicle from 7:30 am to 9:00 am on weekdays, and automatically select the second battery system from 6:00 to 8:00 on weekdays. The vehicle is powered.
控制装置103除了可以通过上述任一种参考信息选择为该车辆提供动力的电池***之外，还可以根据上述参考信息中的两种或两种以上选择电池***。在此情况下，可以为不同的信息设置不同的优先级。控制装置103可以根 据多种信息的优先级，选择为所述车辆提供动力的电池***。The control device 103 can select a battery system in accordance with two or more of the above-described reference information, in addition to the battery system that can power the vehicle by any of the above-described reference information. In this case, different priorities can be set for different information. Control device 103 can be rooted A battery system that powers the vehicle is selected based on the priority of the various information.
例如，该参考信息可以包括用户的输入信息和路况信息，且用户的输入信息的优先级低于路况信息的优先级。在此情况下，用户可以输入期望使用的电池***，但是当路况信息满足一定条件时，控制装置103可以优先根据路况信息选择电池***。再如，用户的输入信息的优先级可以高于路况信息的优先级。在此情况下，当控制装置103根据路况信息选取需要使用的电池***后，用户可以通过输入信息将当前使用的电池***切换为另一电池***。For example, the reference information may include user input information and road condition information, and the priority of the user's input information is lower than the priority of the road condition information. In this case, the user can input the battery system desired to be used, but when the road condition information satisfies certain conditions, the control device 103 can preferentially select the battery system based on the road condition information. For another example, the priority of the user's input information may be higher than the priority of the road condition information. In this case, after the control device 103 selects the battery system to be used according to the road condition information, the user can switch the currently used battery system to another battery system by inputting information.
进一步，当控制装置103可以通过多种方式选择为该车辆提供动力的电池***时，用户可以通过手动输入的方式选择希望控制装置103使用的参考信息。Further, when the control device 103 can select a battery system that powers the vehicle in various ways, the user can select the reference information that the control device 103 is desired to use by manual input.
控制装置103可以通过控制开关(例如可以是金属氧化物半导体(Mental Oxide Semiconductor，MOS)管)的方式控制该第一电池***和/或该第二电池***为该车辆提供动力。 Control device 103 can control the first battery system and/or the second battery system to power the vehicle by controlling a switch, such as may be a Metal Oxide Semiconductor (MOS) tube.
例如，当控制装置103确定该第二电池***适于为该车辆提供动力时，可以通过控制开关将第二电池***对应的动力电路导通，以便控制该第二电池***为车辆提供动力。当控制装置103确定该第二电池***不适于为该车辆提供动力时，可以通过控制开关将第二电池***对应的动力电路关断。For example, when the control device 103 determines that the second battery system is adapted to power the vehicle, the power circuit corresponding to the second battery system can be turned on by controlling the switch to control the second battery system to power the vehicle. When the control device 103 determines that the second battery system is not suitable for powering the vehicle, the power circuit corresponding to the second battery system can be turned off by the control switch.
本发明实施例对该第一电池***和该第二电池***的连接关系不作具体限定。实际中，只要二者的连接关系使得控制装置103能够控制实现上文描述的控制逻辑即可。The connection relationship between the first battery system and the second battery system is not specifically limited in the embodiment of the present invention.

Specifically, when the user determines that there is a charging post available for the driving destination, the first battery system may be selected to power the vehicle. Thus, when the user drives to the destination, the charging station can be used to charge the first battery system. When the user determines that the driving destination does not have a charging stake, the second battery system can be selected to power the vehicle to take the second battery system away from charging after reaching the destination.
