Embodiment 1

[0027] Embodiment one refers to Figure 1-2 , a non-conductive lithium battery charging device for fire prevention, including a box body with a box cover 4 and an electric control system, the box body adopts a cylindrical structure that can withstand 10 pressures, and is made of lightweight fireproof materials. The light fireproof material used in this embodiment is a light metal material with good strength, such as aluminum alloy. The box body is divided into upper and lower spaces, the upper part is the battery compartment 1, and the lower part is the instrument compartment 12. The battery compartment 1 and the instrument compartment 12 are separated by a sealed partition 11 so that any substance in the battery compartment 1 cannot enter the instrument compartment 12. The battery compartment 1 side bulkhead is provided with an opening, and one side of the case cover 4 adopts a hinge 3 to be movably connected with the battery compartment 1, and the other side adopts a quick t...

Abstract

The invention discloses a lithium battery non-conductive charging device capable of preventing fire, which comprises a box body with a box cover and an electric control system, wherein the upper part of the box body is a battery compartment, and the lower part of the box body is an instrument compartment; an aerosol vehicle-mounted fire extinguishing device is mounted in the battery compartment; the electric control system comprises a current sampler, a current lead, a microprocessor, an alarm and a charging power supply; and the microprocessor is connected with the charging power supply, the alarm and the current sampler, and when the charging is finished or the current signal is abnormal, the microprocessor sends an instruction to control the alarm to send an alarm signal. The innovation point of the invention is that the source and range of battery fire can be controlled in the battery compartment, and the aerosol vehicle-mounted fire extinguishing device is used for extinguishing fire, so that the possibility of fire caused by battery combustion is thoroughly prevented. The device adopts a sealed charging space, oxygen is isolated firstly, and combustion is avoided at high temperature; and high-temperature substances of the second injection are limited in a tank body, so that external inflammable substances cannot be ignited.

Description

technical field [0001] The invention relates to the technical field of battery charging safety, in particular to a large-capacity lithium battery fire prevention facility, and more specifically, to a non-conductive lithium battery charging device for fire prevention. Background technique [0002] There are a large number of electric vehicles in my country, and the lithium batteries of electric vehicles are taken down for charging, causing major fires from time to time. In addition, the same problem exists when charging large-capacity lithium batteries for other purposes. Although existing chargers also have some fire prevention measures and technologies in the charging process, accidental battery charging fires and fires occur from time to time. [0003] The reason for the lithium battery charging fire is that the internal failure of the battery generates heat. When the temperature rises to a certain level, it will cause combustion and volume expansion, and finally burst and...
