Background technique
The advantages that lithium battery is with its high-energy density, long-life, be widely used in electric car, standby power system,
In micro-grid energy storage system, dynamic lithium battery contains the structures such as core, electrolyte, shell, cover board.In over-charging of battery protection problem
On, when increasing SSD and FUSE composite structure usually using battery core cover board at present, but overcharging after battery parallel connection, there are SSD
The situation inconsistent by current ratio, failure is overcharged so as to cause battery side by side with FUSE.
Utility model content
Based on technical problem present in background technique, the utility model proposes a kind of dynamic lithium batteries to overcharge protection dress
It sets.
The utility model proposes a kind of dynamic lithium battery overcharge protective device, including cell substrates, overcharge screening glass, mistake
It fills rotating sheet and overcharges cutting off tool；Mounting groove is equipped in substrate, installation trench bottom is equipped with the ventilation being connected to lithium battery interior
Mouthful；It overcharges screening glass to be arranged in mounting groove and connect with cell substrates, it is electric with lithium battery external respectively to overcharge screening glass both ends
Road, internal circuit connection；Rotating sheet setting is overcharged in mounting groove and is located at and is overcharged below screening glass, rotating sheet and battery are overcharged
Substrate rotating connection；Overcharge cutting off tool be located at overcharge screening glass and overcharge between rotating sheet and connect with rotating sheet is overcharged, and
And it overcharges cutting off tool and overcharges and be reserved with gap between screening glass.
Preferably, overcharging screening glass includes the first sheet body and the second sheet body interconnected, and the first sheet body and second
Body junction is equipped with the indentation easily being switched off.
Preferably, rotating sheet is overcharged close to screening glass side is overcharged equipped with boss, is overcharged cutting off tool and is fixed on boss.
The utility model proposes a kind of dynamic lithium battery overcharge protective device, the sealing space inside dynamic lithium battery
In, if battery overcharges, battery is overheated, and electrolyte punctures after lithium platingactive, internal micro-short circuit or apparent battery over-discharge
When, inside battery air pressure rises, and inside battery will do it chemical reaction and generate bulk gas, reaches to gas value and overcharges rotating sheet
When eversion pressure, rotating sheet overturning is overcharged, boss moves upwards a distance, and it overcharges cutting off tool and boss fastening is assembled,
A distance is moved upwards, the indent locations that cutting is overcharged screening glass by cutting off tool are overcharged, cutting battery and external circuit join
System, to carry out overcharging protective effect, to avoid battery further out of control and explosion.The utility model structure is simple.It can be with
It solves battery cell parallel connection and overcharges Problem of Failure, reduce the out of control and risk of explosion because of battery caused by overcharging, improve cell safety
Performance.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of dynamic lithium battery overcharge the structural schematic diagram of protective device；
Fig. 2 be the utility model proposes a kind of dynamic lithium battery overcharge and overcharge the structural representation of screening glass in protective device
Figure；
Fig. 3 be the utility model proposes a kind of dynamic lithium battery overcharge and overcharge the side of rotating sheet in protective device and attempt.
Specific embodiment
- Fig. 3 referring to Fig.1, the utility model proposes a kind of dynamic lithium batteries to overcharge protective device, including cell substrates 1, mistake
Screening glass 2 is filled, rotating sheet 3 is overcharged and overcharges cutting off tool 4；Wherein:
Mounting groove is equipped in substrate 1, installation trench bottom is equipped with the blow vent being connected to lithium battery interior.
It overcharges screening glass 2 to be arranged in mounting groove and connect with cell substrates 1, it is electric with lithium respectively to overcharge 2 both ends of screening glass
Pond external circuit, internal circuit connection.It overcharges screening glass 2 and includes the first sheet body interconnected and the second sheet body, and first
Body and the second sheet body junction are equipped with the indentation 5 easily being switched off.
The setting of rotating sheet 3 is overcharged in mounting groove and is located at and is overcharged below screening glass 2, rotating sheet 3 and cell substrates 1 are overcharged
Rotation connection overcharges rotating sheet 3 close to 2 side of screening glass is overcharged and is equipped with boss 6.It overcharges rotating sheet 3 and meets flip bar in air pressure
When part, the overturning of rotating sheet 3 is overcharged.
Overcharging cutting off tool 4 is a kind of sharp cutting tool, overcharges cutting off tool 4 and is located at and overcharges screening glass 2 and turn over overcharging
It between rotor 3 and is fixed on the boss 6 for overcharging rotating sheet 3, and overcharges cutting off tool 4 and overcharge and reserved between screening glass 2
There is gap.
The utility model proposes a kind of dynamic lithium battery overcharge protective device, the sealing space inside dynamic lithium battery
In, if battery overcharges, battery is overheated, and electrolyte punctures after lithium platingactive, internal micro-short circuit or apparent battery over-discharge
When, inside battery air pressure rises, and inside battery will do it chemical reaction and generate bulk gas, reaches to gas value and overcharges rotating sheet
When 3 eversion pressure, the overturning of rotating sheet 3 is overcharged, boss 6 moves upwards a distance, overcharges cutting off tool 4 and the fastening of boss 6 fills
Match, also move upwards a distance, overcharges cutting off tool 4 for cutting and overcharge 5 position of indentation of screening glass 2, cutting battery and outer
Portion's circuit connection, to carry out overcharging protective effect, to avoid battery further out of control and explosion.The utility model structure letter
It is single.It can solve battery cell parallel connection and overcharge Problem of Failure, reduce the out of control and risk of explosion because of battery caused by overcharging, improve electricity
