Description

Battery device and method for setting battery device on equipment

Technical Field

The present application relates to an electrical energy device, and more particularly, to a battery device.

Background

In recent years, with the development and progress of scientific technology, the demand of electric equipment to get rid of the constraint of a power supply line is increasing, and the application of a battery is becoming wider. Accordingly, in order to reduce the number of times of replacement of the non-rechargeable battery or to reduce the number of times of charging of the rechargeable battery, the single service time of the battery is increased, and the application of the large-capacity battery is increasing; in some high-power application scenarios, high-power batteries are increasingly used. However, the problems of equipment damage and personal injury caused by the danger of battery combustion are more and more prominent with the wide use of batteries, especially high-capacity and high-power batteries.

The combustion of the battery can be caused by spontaneous combustion or ignition by other combustion matters, and other combustion matters also comprise other combustion batteries and the like; the danger of battery burning not only causes equipment damage, but also causes personal hazard.

The danger of battery burning may occur in the scenes of battery short circuit, breakage, high temperature, deformation, fire and the like. Such as: when the battery is short-circuited, the current acts on the internal resistance, high temperature is instantaneously generated in the battery, the internal pressure increases the expansion of the battery, and the originally isolated oxidant and the reducing agent in the battery are in extrusion contact and are burnt; or the internal pressure is increased, the battery is expanded, the battery package is damaged, and the internal combustible material is burnt in contact with air; or the battery is damaged and packaged at high temperature when being on fire, the combustible materials in the battery are leaked, and the battery is burnt when being on air; or the battery package is damaged by external force, the internal combustible material leaks, and the battery package burns when meeting air.

The risk of burning the battery is inherent and extrinsic.

The intrinsic cause of the risk of burning the battery is the defect factor of the battery itself, and also the aging factor of the battery itself. Cell itself defect factor: design defects and production defects are common, such as internal sporadic short circuits caused by production defects. Cell self aging factor: some of them are aged in use or in storage time, and some of them are short-circuited accidentally due to internal crystallization phenomenon caused by high temperature of the environment.

External causes of the risk of burning the battery include improper use of the battery and unexpected accidents of the battery. Battery misuse factor: some are because of external short circuits during use; there are also rechargeable batteries which are overcharged during use. Battery accident factor: such as battery collision accidents, battery puncture accidents, extrusion of the battery, high temperature of the battery caused by accidents, battery damage and the like during use.

Before the battery burns, a continuous heat accumulation and temperature rise process exists, and the temperature rise can be continued until the battery burns out; in the normal use process of the battery, although the temperature is also increased, the passive heat dissipation capacity is increased along with the temperature increase and the temperature difference increase, or the intervention of active heat dissipation is always limited in a reasonable temperature range; specific parameters of the above reasonable temperature range are generally provided by the battery provider, and the user should use the battery below the maximum temperature of the above reasonable temperature range; the highest temperature in the reasonable temperature range is called as the normal working highest temperature; when the battery is kept continuously heated, the temperature exceeds the reasonable temperature range, the battery is called as abnormally high temperature or the battery is overheated.

The battery is abnormally high in temperature until the ignition point is exceeded, and general combustion, explosion and deflagration of the battery can occur. Unlike normal combustion, so-called explosion is extremely intense combustion of a battery, during which the volume of the battery instantaneously increases and breaks. Unlike normal combustion and explosion, deflagration is the normal alternate occurrence of combustion and explosion of a battery. The general combustion, explosion and deflagration of the battery belong to the broad combustion. Combustion as used herein refers to combustion in a broad sense.

The battery burns, the process may be: general combustion, explosion, first general combustion and then explosion, first explosion and then general combustion, first general combustion and then explosion and then continuing general combustion, etc.

The battery burns, which may cause damage to equipment and even personal injury. In particular, when a plurality of batteries are used, the combustion of one battery is spread to the combustion of the other battery, which causes more serious equipment damage and personal injury.

In the existing battery device, in order to reduce equipment damage and personal hazard caused by the danger of battery combustion, the following steps are adopted: the battery raw materials are completely replaced by novel flame-retardant and flame-retardant materials, the method has the research and development difficulties such as battery energy density, battery material cost and the like, and the performance of the flame-retardant and flame-retardant materials cannot reach the degree of incombustibility at present.

Or adopts the following steps: the fire extinguishing device is arranged for the battery, the volume, the weight, the cost and other factors of the fire extinguishing device are considered, the capacity of the fire extinguishing device and the fire extinguishing agent contained by the fire extinguishing device are limited, the fire is difficult to thoroughly extinguish by the method, the battery is left in situ after the fire extinguishing agent is released, the risk of re-combustion is still caused after the fire extinguishing, and equipment damage and personal hazard are caused.

Or adopts the following steps: the battery is provided with a device for coating the flame-retardant material, and the thickness, the weight, the cost and other factors of the material are considered to limit the flame-retardant effect.

The battery is dangerous to burn, and the damage to equipment and even personal injury can be caused. In particular, when a plurality of batteries are used, the combustion of one battery is spread to the combustion of the other battery, which causes more serious equipment damage and personal injury.

The inventors have found that the risk of combustion of the battery is imminent and that there are often: abnormal phenomena such as battery deformation, battery leakage, abnormal high temperature, abnormal change of battery voltage, abnormal change of battery current and the like; when the battery is in danger of burning, the process may be: burning, explosion, first burning and then explosion, first explosion and then combustion, first burning and then explosion and then continuous combustion and the like; the voltage and current output by the battery will change abnormally when the battery is about to have a combustion risk or has a combustion risk, for example: before the battery punctured by the conductor burns, the voltage and current may decrease sharply to near zero; when the battery is connected in series or parallel with other batteries as a part of the battery pack, the voltage and current increase sharply when burning is imminent, and even exceed the rated values, negative values may occur.

In the technical scheme provided by the embodiment, the explosion device is arranged at the battery installation position, so that the battery is burnt, or when the abnormal phenomenon occurs in the battery, the battery is fried away from the battery installation position, and the problems of equipment damage and personal hazard caused by the combustion of the battery are solved.

Fig. 1 is a schematic overall structure of the battery device provided in this embodiment 1, and fig. 2 is a schematic overall structure of the battery device provided in this embodiment 1, in which no battery is mounted in both the first battery mounting position and the second battery mounting position. Referring to fig. 1 and 2 in combination, the present embodiment provides a battery device: comprising a device body and a battery.

If the battery burns, the explosive charge will detonate, the battery is blasted off the device body.

when the battery generates abnormal high temperature, even if the battery is not yet burnt, the explosive is exploded as long as the explosive is subjected to the abnormal high temperature, and the explosive is burnt as the abnormal high temperature possibly is a combustion precursor and possibly causes combustion, so the explosive is fried away from the battery in advance to avoid the explosive from being burnt on the installation position main body.
