Abstract
The utility model discloses a power battery safety structure. The power battery safety structure comprises an end cover which is arranged on a battery, wherein the end cover is provided with a pressure-bearing exhaust valve which is used for discharging air and releasing pressure to the outside, and a gas-liquid separation mesh panel is arranged on the inner side of the end cover and at the pressure-bearing exhaust valve. The battery end cover is provided with the pressure-bearing exhaust valve which can bear the rated pressure and discharge the air to the outside, when the pressure inside the battery exceeds the rated pressure, the pressure-bearing exhaust valve discharges the air to the outside so as to release the pressure inside the battery, the battery can be prevented from being damaged by the high pressure, and the service life of the battery can be efficiently prolonged.
Description
Technical field
The utility model relates to a kind of safeguard construction of electrokinetic cell.
Background technology
Employed electrokinetic cells such as electric motor car, electric automobile, airport ground transfer car mostly are lithium battery or lead-acid battery.Battery can produce a large amount of heats at work, is that internal temperature of battery raises, and pressure increases.Thereby cause the battery case distortion, the space in the battery pack between the single battery diminishes, and the battery explosion accident takes place easily.
At present mainly by in the battery case welding or rivet that safe valve block addresses this problem.But the rising along with temperature, internal temperature of battery and pressure increase, the safety valve sector-meeting is in the explosion of rated pressure scope, can't repair replacing after the safe valve block explosion, battery can only be scrapped, and cell internal pressure still can make electrolyte spray from safe valve block, corrodes corresponding parts, produces short-circuit fire or injures personal property.The sound of explosion also causes related personnel's fear easily.
Summary of the invention
The utility model provides a kind of safe electrokinetic cell safeguard construction that uses for solving the problem that prior art in use exists.
The technical scheme that the utility model solves existing issue is: a kind of electrokinetic cell safeguard construction, comprise the end cap that is arranged on the battery, as improvement, described end cap is provided with the pressure-bearing vent valve of outside unidirectional exhaust pressure relief, and described end cap inboard is positioned at pressure-bearing vent valve place and is provided with gas-liquid separation net sheet.
As further improvement, described end cap is provided with the interface of a connection pressure-bearing vent valve, and described gas-liquid separation net sheet is arranged at the interface inboard, can inject electrolyte in battery by dismounting pressure-bearing vent valve, guarantees the battery flying power.
The utility model and prior art, its beneficial effect is the pressure-bearing vent valve that bears specified pressure, outside exhaust end cover for battery cells setting, cell internal pressure surpasses rated pressure, the outside exhaust of pressure-bearing vent valve, alleviate cell internal pressure, prevent the excessive damage battery of pressure, effectively extending battery life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the implementation case comprises the end cap 1 that is arranged on the battery, is arranged at the binding post on the end cap 1, and end cap 1 is provided with the pressure-bearing vent valve 2 of outside unidirectional exhaust pressure relief, and end cap 1 inboard is positioned at pressure-bearing vent valve 2 places and is provided with gas-liquid separation net sheet 3.
End cap 1 is provided with the interface 4 of a connection pressure-bearing vent valve 2, and gas-liquid separation net sheet 3 is arranged at interface 2 inboards.
During use, cell internal pressure exceeds the preset pressure of pressure-bearing vent valve 2, under the effect of gas-liquid separation net sheet 3, pressure-bearing vent valve 2 outwards or can be to fixing container exhaust pressure relief, prevent the battery case deformation fracture, can inject the electrolyte extending battery life in from interface 4 to battery by dismounting pressure-bearing vent valve 2.
Claims (2)
1. an electrokinetic cell safeguard construction comprises the end cap that is arranged on the battery, it is characterized in that: described end cap is provided with the pressure-bearing vent valve of outside unidirectional exhaust pressure relief, and described end cap inboard is positioned at pressure-bearing vent valve place and is provided with gas-liquid separation net sheet.
2. electrokinetic cell safeguard construction as claimed in claim 1 is characterized in that: described end cap is provided with an interface that connects the pressure-bearing vent valve, and described gas-liquid separation net sheet is arranged at the interface inboard.
