Problems solved by technology

However, since the burning point is inside the battery pack, it is difficult for the fluid fire extinguishing agent to be sprayed into the battery pack for timely and effective fire extinguishing
Secondly, since the burning point is inside the battery, a large amount of fluid fire extinguishing agent is required for each fire extinguishing, resulting in a great waste of fire extinguishing agent

Embodiment 1

[0044] Such as figure 1 As shown, a charging compartment fire isolation method includes the following steps:

[0045] S101: Obtain the state information of the battery pack in the charging compartment. In some embodiments, the state information of the battery pack includes the inner core temperature of the battery pack and / or the smoke concentration near the battery pack, and each battery is obtained through the battery management system The temperature of the inner core of the battery pack or the smoke concentration near the battery pack can be obtained through the smoke sensor installed near the exhaust port of the battery pack. In some other embodiments, the state information of the battery pack also includes parameters that can reflect the abnormality in the charging compartment, such as the change of the battery pack current and the temperature near the battery pack.

[0046] S102: Analyze the status information of the battery pack to determine whether the battery pack h...

Embodiment 2

[0088] Such as Figure 12 As shown, a charging compartment battery pack isolation structure includes a charging compartment control system configured to implement the charging compartment fire isolation method. The charging compartment battery pack isolation structure also includes a battery pack transfer structure 2 and an isolating device 3, the isolating device is arranged outside the charging compartment 100, and the charging compartment control system removes the abnormal battery according to the acquired state information of the battery pack 1. The pack 1 is transported to the isolation device 3 through the battery pack transfer structure 2 .

[0089] Such as Figure 12 As shown, the battery pack transfer structure 2 includes a battery exchange trolley 6 and a trolley transport track 4. The battery exchange trolley 6 initially stops in the charging compartment 100, and the trolley transport track extends from the charging compartment to the outside of the charging compa...

Abstract

The invention provides a fire-fighting isolation method for a charging bin. The fire-fighting isolation method comprises the following steps: acquiring state information of a battery pack in the charging bin; analyzing the state information of the battery pack to judge whether the battery pack is abnormal or not; if the state of the battery pack is abnormal, sending a fault code, cutting off a charging power loop of the battery pack, and controlling the battery pack transfer structure to convey the abnormal battery pack to the isolation device; if the state of the battery pack is normal, continuously charging the battery pack. The invention further provides a charging bin battery pack isolation structure applying the method. By accurately acquiring the state information of the battery pack, the battery pack transfer structure controls the abnormal battery pack to be transferred out of the charging bin, damage to the charging bin is avoided, and the problems that in the prior art, a fire extinguishing scheme for the battery pack is low in fire extinguishing efficiency and high in cost are solved.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a fire-fighting isolation method for a charging compartment and a battery pack isolation structure for the charging compartment. Background technique [0002] In the prior art, multiple battery packs composed of lithium-ion batteries are placed in the charging compartment of the power station. Once a certain battery pack is thermally out of control, a chain reaction will occur, causing the rest of the battery packs in the charging compartment to burn. There will be an explosion in the final charging compartment. In order to avoid the above-mentioned accidents and enhance the safety of the charging compartment of the power station, in the prior art, a gas fire extinguishing device is usually used to spray a fluid fire extinguishing agent on the abnormal battery pack. However, since the burning point is inside the battery pack, it is difficult for the fluid fire extinguish...
