新能源汽车有多种类型:纯电动汽车、增程式电动汽车、各种燃料电池汽车、各类混合动力汽车、太阳能汽车、低速电动汽车等。新能源汽车采用电力驱动或兼有电力驱动与其它驱动方式,电能来源于车载其它能源发电或外部充电,还需用动力电池进行电能的储存和输出。动力电池的电能来源除车载其它能源发电外,可通过外部充电或直接更换电池的方式。There are many types of new energy vehicles: pure electric vehicles, extended range electric vehicles, various fuel cell vehicles, various types of hybrid vehicles, solar vehicles, low-speed electric vehicles, etc. New energy vehicles use electric drive or both electric drive and other driving methods. The electric energy comes from other on-board energy generation or external charging. Power batteries are also needed to store and output electric energy. In addition to other onboard energy sources, the power source of the power battery can be externally charged or directly replaced by the battery.
外部充电时间长,且易出现充电位被其它车辆占用等情况,不能完全满足新能源汽车补充电能的需要。直接更换电池的方式速度快,可以与充电方式共同应用,弥补充电方式的不足。现在的换电方式采用快换结构,更换动力电池速度较快,但由于动力电池体积大、重量也大,需要专用设备,配置换电点投入大,布点不易。而且由于动力电池个体体积大,不方便利用新能源汽车不同部位分散的各种空间。The external charging time is long, and the charging position is easily occupied by other vehicles, which cannot fully meet the needs of new energy vehicles to supplement electrical energy. The method of directly replacing the battery is fast, and can be applied together with the charging method to make up for the deficiency of the charging method. The current power replacement method uses a quick-change structure, and the power battery replacement speed is faster. However, due to the large size and weight of the power battery, special equipment is required, and the configuration of the power replacement point is large, and the layout is not easy. Moreover, due to the large size of the power battery, it is inconvenient to use the various spaces scattered in different parts of the new energy vehicle.

相对于新能源汽车,人工快换型通用动力电池的尺寸小,单个电池的最大面的面积或最大投影面积与新能源汽车中的乘用车的投影面积相差两个数量级,易于在新能源汽车的各种位置布局。因厚度小,可布局于狭窄空间,如乘用车的车内地板之下;因外形各面积小,因此可布局位置多,乘用车的各座椅前脚位的地板之下、前排座椅轨道下的地板之下、后排座位之下、车的前后舱(设置于较安全的空间位置)都可布局安装,还可根据车身特点设置于其它位置,可应用创新的思路。在较大型的车辆如客车、货车中需用人工快换型通用动力电池的,由于车体较大,也容易布局。因尺寸小,还可灵活组合,如在不同车的相似可布局位置,由于可布局位置尺寸大小不同,布局时可采用不同的电池个数的组合,因此适用性广。由于重量轻,换电时负重小,适合多数人单人单手提放,并连续更换多个电池,换电可用专用手持工具更换,设置换电点可不配备机械设备,布点容易,易于通用。还可兼用于其它车辆,如低速电动汽车(又称低速电动车)、二、三轮的电动车。因此人工快换型通用动力电池通用性很强。Compared with new energy vehicles, the size of the manual quick-change general-purpose power battery is small. The area of the largest surface of the single battery or the maximum projected area differs from the projected area of the passenger car in the new energy vehicle by two orders of magnitude, which is easy to use in new energy vehicles. Layout of various positions.

In larger vehicles such as passenger cars and trucks, manual quick-change general-purpose power batteries are required, because the car body is large, it is also easy to lay out. Because of its small size, it can also be flexibly combined. For example, in similar layout positions of different vehicles, due to the different sizes of layout positions, different combinations of battery numbers can be used for layout, so the applicability is wide. Due to its light weight and small load when changing power, it is suitable for most people to put it in a single hand and replace multiple batteries in a row. The power can be replaced with a special hand-held tool. The power exchange point can be set without mechanical equipment, and the layout is easy and easy to use.
