多动力电池并联充电装置  Multi-power battery parallel charging device
技术领域 Technical field
本发明涉及一种可以实现多个动力电池并联充电的装置。  The present invention relates to an apparatus that can realize parallel charging of a plurality of power batteries.
背景技术 Background technique
目前, 公知的换电式电动车辆的动力电池, 大都是将许多单体电池按照一定 规则串并联后组成一个大的动力电池并安装于一个电池包内, 如中国专利公告 At present, the power batteries of the well-known electric-type electric vehicles are mostly composed of a plurality of single cells connected in series and in parallel according to a certain rule to form a large power battery and installed in a battery pack, such as the Chinese patent announcement.
CN101559758公开的那样。 当动力电池中储存的电能耗尽时, 可以到电池更换站 更换一个充满电的动力电池, 从而避免插电式电动车辆需长时间充电所造成的诸 多不便。 但是, 为了保证电动车辆具有足够的动力和续驶能力, 就必须配备体积 和重量相当大的动力电池, 需要借助复杂昂贵的专用机电装备实施更换作业。 As disclosed in CN101559758. When the power stored in the power battery is exhausted, a fully charged power battery can be replaced at the battery exchange station, thereby avoiding the inconvenience caused by the long-term charging of the plug-in electric vehicle. However, in order to ensure that the electric vehicle has sufficient power and continuous driving capability, it is necessary to equip the power battery with a considerable volume and weight, and it is necessary to carry out the replacement work by means of complicated and expensive special electromechanical equipment.
同时, 将众多的动力电池集成在一个动力电池中, 由于不同单体电池的性能 之间存在不一致性, 在使用时容易产生起因于个别单体电池过充电或者过放电的 动力电池组故障。 最糟糕的是, 在电动车辆行驶途中出现动力电池组严重故障或 者电能耗尽时, 车辆使用者将陷于难以摆脱的困境。  At the same time, a large number of power batteries are integrated in one power battery. Due to the inconsistency between the performances of different single cells, it is easy to cause a power battery pack failure caused by overcharging or overdischarging of individual cells during use. Worst of all, when the power battery pack is seriously faulty or the power is exhausted while the electric vehicle is running, the vehicle user will be in a difficult situation.
一个容易的代替方案是用若干个重量和体积小得多的动力电池取代上述的 大动力电池, 将这样的小动力电池制作成适宜人力操作的结构和重量, 更换动力 电池时就不必借助上述专用机电装备; 当某一单体电池出现故障时, 造成的损失 至多涉及容纳它的小动力电池; 如果电动车辆行驶途中出现电能耗尽的情况, 只 要将所需数量的动力电池运送至所述电动车辆处人工更换即可。  An easy alternative is to replace the above-mentioned large power battery with several power batteries with much smaller weight and volume. The small power battery is made into a structure and weight suitable for human operation, and it is not necessary to use the above special purpose when replacing the power battery. Electromechanical equipment; When a single battery fails, the loss is at most related to the small power battery that houses it; if the electric vehicle runs out during the running, the required number of power batteries are transported to the electric The vehicle can be replaced manually.
进一步地, 可以考虑建设集中充电工厂专业从事动力电池的充电和日常保 养, 使用专用的动力电池运送车辆将充满电的动力电池分送至各个电池更换站, 电池更换站只需具有一定的停车位和动力电池存放空间就可实施动力电池更换 服务。  Further, it is conceivable to construct a centralized charging factory specializing in the charging and daily maintenance of the power battery. The dedicated power battery is used to transport the vehicle to distribute the fully charged power battery to each battery replacement station.

如此以来,如何实现动力电池在充电工厂和电池更换站内储放、短距离搬运、 向运输车辆装载以及动力电池与充电机之间电连接的快捷便利就成为需要解决 的问题。  In this way, how to realize the quick and convenient storage and release of the power battery in the charging factory and the battery exchange station, short-distance transportation, loading to the transportation vehicle, and electrical connection between the power battery and the charger becomes a problem to be solved.
对单电池来讲, 理想的充电方式是单个动力电池单独充电, 但是将每个动力 电池都单独充电, 需要众多的动力电池座, 各动力电池座分散设置, 占用了大量 空间, 而且, 要先将各个动力电池安装在动力电池座上, 然后还要将各个动力电 池座一一插设在与电源相连的插座上, 这是一项繁重的工作, 费时费力, 可操作 性不强。 For a single battery, the ideal charging method is that a single power battery is separately charged, but each power battery is separately charged, and a large number of power battery holders are required, and each power battery holder is dispersedly disposed, occupying a large amount.
