一种锂电池用充电储能装置以及降温运行方法A charging energy storage device for a lithium battery and a cooling operation method

技术领域technical field

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state. Lithium-ion batteries do not contain lithium in the metallic state and are rechargeable.

During transportation or use, the batteries collide with each other due to bumps, which reduces the service life of the battery and the battery cover.

另外，现有的锂离子电池用于很多电子产品上，这便需要对其经常充电，然而现有的充电装置只能对单一的电池充电，而且在充电的时候，储电装置在输出的过程中会产生很大的热量，从而造成电池受热膨胀，最终使得电池使用寿命缩短，而且过热还容易导致充电装置的损坏，其实用性并不是很强。In addition, the existing lithium-ion battery is used in many electronic products, which requires frequent charging.

实施例2：本发明还提供一种锂电池用充电储能装置降温运行方法，包括以下步骤：Embodiment 2: The present invention also provides a method for cooling operation of a charging energy storage device for a lithium battery, comprising the following steps:

第一步，将锂电池放置于容纳腔3内，锂电池与外界隔绝。In the first step, the lithium battery is placed in the accommodating cavity 3, and the lithium battery is isolated from the outside world.

第二步，根据指示灯16显示的储能阈值，判断储电装置11是否需连接外部电源，当指示灯16显示的储能阈值小于锂电池需补充电量值，将该锂电池用充电储能装置连接外部电源，再进行充电，当指示灯16显示的储能阈值大于锂电池需补充电量值，无需连接外部电源，直接进行充电。The second step is to determine whether the power storage device 11 needs to be connected to an external power source according to the energy storage threshold displayed by the indicator light 16. When the energy storage threshold displayed by the indicator light 16 is less than the value of the lithium battery that needs to be supplemented, the lithium battery is charged for energy storage. The device is connected to an external power supply and then charged. When the energy storage threshold displayed by the indicator light 16 is greater than the value of the lithium battery that needs to be supplemented, the device can be directly charged without connecting to an external power supply.

第三步，对锂电池开始充电。The third step is to start charging the lithium battery.

第四步，控制单元17根据温度传感器12的反馈，驱动散热风扇14使储电装置11处于最佳工作温度，根据温度传感器12的检测到储电装置11的温度大于预定值，控制单元17时驱动散热风扇14进行散热，并在检测到储电装置11的温度低于预定值时关停散热风扇14，且预定值为+10℃范围内。In the fourth step, the control unit 17 drives the cooling fan 14 according to the feedback from the temperature sensor 12 to keep the power storage device 11 at the optimum working temperature. The cooling fan 14 is driven to dissipate heat, and when it is detected that the temperature of the power storage device 11 is lower than a predetermined value, the cooling fan 14 is turned off, and the predetermined value is within the range of +10°C.

在使用中，in use,

当锂电池需要充电时，只需将锂电池放置容纳腔3内，再将锂电池承载盒2通过转换连接器和储电盒1连接即可，当储电盒1内的储电装置11电量不足时，将储电盒1上的充电接头13与外部电源连接，便可实现继续充电。When the lithium battery needs to be charged, it is only necessary to place the lithium battery in the accommodating cavity 3, and then connect the lithium battery carrying box 2 to the power storage box 1 through the conversion connector. When the power of the power storage device 11 in the power storage box 1 When it is insufficient, the charging connector 13 on the power storage box 1 can be connected to an external power source, and then the charging can be continued.

综上所述，该锂电池用充电储能装置，便于拆装和安装，也便于后期的维护。To sum up, the rechargeable energy storage device for the lithium battery is convenient for disassembly and installation, as well as for later maintenance.
