Description
Technical field:
The present invention relates to a kind of battery modules of included energy release channel function, belong to battery technology field.
Background technique:
Lithium ion battery easily by internal short-circuit, improper use, physics abuse, manufacturing defect or is exposed to extreme external temperature
Cause thermal runaway.When thermal runaway occurs, the heat of generation is enough to lead to the material combustion near cells burst and battery.
Since the battery temperature of thermal runaway increases rapidly, the temperature of adjacent cell can also be increased in battery pack.If allowed
The temperature of these adjacent cells increases in the clear, they may also enter thermal runaway state.
Therefore, it is necessary to monitor the thermal behavior of the battery in battery pack, and alleviate the event once detecting thermal runaway
Influence to attempt to prevent the adjacent cell in initial thermal runaway event propagation to battery pack.
Summary of the invention:
The present invention is to provide a kind of included energy release channel function to solve the above-mentioned problems of the prior art
Battery modules, be used to mitigate the influence of thermal runaway in battery pack.
The technical solution adopted in the present invention has: a kind of battery modules of included energy release channel function, including energy
Release channel, the battery core equipped with battery core explosion-proof valve, positive bus, negative bus-bar, mould group upper cover plate, mould group lower cover plate and
It is weak that the first weak area, the second weak area, third are arranged on the mould group upper cover plate right above battery core explosion-proof valve for fixing bolt
Area, the 4th weak area, the 5th weak area, the 6th weak area, the 7th weak area, the 8th weak area, the 9th weak area, the tenth weakness
Area, the 11st weak area and the 12nd weak area, the energy release channel are arranged in mould group upper cover plate and mould group lower cover plate
On, positive bus and negative bus-bar are separately mounted to mould group upper cover plate, on mould group lower cover plate by the fixing bolt.
The invention has the following beneficial effects: the battery modules of the included energy release channel function of the present invention, cost is relatively low,
Structure is practical, and mitigating thermal runaway battery core influences obvious, great cost performance on battery core around.
Detailed description of the invention:
Fig. 1 is the top view of the battery modules of the included energy release channel function of the present invention.
Fig. 2 is the perspective view of the battery modules of the included energy release channel function of the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
It please refers to shown in Fig. 1 and Fig. 2, the battery modules that the present invention carries energy release channel function include that energy release is logical
Road 13, the battery core 15 equipped with battery core explosion-proof valve, positive bus 17, negative bus-bar 18, mould group upper cover plate 14, mould group lower cover plate
16 and fixing bolt 19, be arranged on mould group upper cover plate 14 right above battery core explosion-proof valve the first weak area 1, the second weak area 2,
Third weak area 3, the 4th weak area 4, the 5th weak area 5, the 6th weak area 6, the 7th weak area 7, the 8th weak area the 8, the 9th
Weak area 9, the tenth weak area 10, the 11st weak area 11 and the 12nd weak area 12, energy release channel 13 are arranged in mould
On group upper cover plate 14 and mould group lower cover plate 16, positive bus 17 and negative bus-bar 18 are separately mounted to mould by fixing bolt 19
On group upper cover plate 14, mould group lower cover plate 16.
Once thermal runaway occurs for the battery modules battery core that the present invention carries energy release channel function, energy breaks through electricity first
And then battery core explosion-proof valve on core breaks through the first weak area 1, the second weak area 2, third weak area 3, the 4th weak area 4,
Five weak areas 5, the 6th weak area 6, the 7th weak area 7, the 8th weak area 8, the 9th weak area 9, the tenth weak area the 10, the 11st
Weak area 11 and the 12nd weak area 12 are flowed along mould group upper cover plate 14 and are flowed eventually by energy flow-guiding channel 13 is unified
To Battery case prescribed energy release channel, discharges, greatly reduced by single battery core eventually by the relief valve on cabinet
The influence failed to battery core around.
The battery modules that the present invention carries energy release channel function mitigate the influence of single battery thermal runaway, to prevent
Adjacent cell in thermal runaway event propagation to battery pack minimizes battery pack and subsidiary damage and personnel hazard.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
