Abstract
The utility model discloses a kind of primary lithium battery pack with safety system, belong to power technique fields.It comprises the battery pack be made up of monomer disposable lithium-battery, cell connector and wire series and parallel, also comprises battery pack safety system, and it is made up of diode, self-resetting type element and Temperature protection; In battery pack, after the series connection of each branch road cell, positive pole is connected with diode respectively, to be connected in parallel output by branch road positive pole each after diode; Export after being connected with self-resetting type element and Temperature protection after each branch road negative pole is connected in parallel.The utility model structure is simple and easy to assembling; access battery pack safety system adds the fail safe of battery pack; battery pack safety system has battery short circuit, overcurrent, cross put, excess temperature, the defencive function such as charging; can the safe handling of available protecting primary lithium battery pack, extend its useful life.
Description
Technical field
The utility model relates to a kind of chemical power source, especially primary lithium battery pack, belongs to power technique fields.
Background technology
Instrument and meter power supply, particularly communication power supply need to configure high-octane primary lithium battery pack.Primary lithium battery pack in abuse conditions, as without effective protection, easily there is overcurrent, cross put, excess temperature, the phenomenon such as charging, thus cause battery leakage and damage equipment, the security incident of battery explosion even occur.Therefore, existing communication power supply many employings configuration three kinds of electronic devices and components are as the battery pack of protection: ensure battery pack not excess temperature with Temperature protection; With current insurance (fusible link) stop battery pack to be short-circuited, over-current phenomenon avoidance; Ensure that battery pack crosses the fail safe of putting and charging with diode.The drawback that this protected mode exists has 2 points: one be when battery pack be short-circuited, overcurrent or unusual misoperation cause battery pack short circuit time, after fusible link fuses, need manually to change fusible link, Comparision is loaded down with trivial details; Two is if battery pack needs sealing, and after fusible link fusing, cannot change fusible link, battery pack can only be scrapped, and causes unnecessary waste.
Utility model content
For existing communication battery pack Problems existing, the utility model provides a kind of when recovering normal primary lithium battery pack after short circuit, overcurrent elimination.
The utility model solves the technical scheme that its technical problem adopts: with the primary lithium battery pack of safety system, comprise the battery pack be made up of monomer disposable lithium-battery, cell connector and wire series and parallel, also comprise battery pack safety system, it is made up of diode, self-resetting type element and Temperature protection; In battery pack, after the series connection of each branch road cell, positive pole is connected with diode respectively, to be connected in parallel output by branch road positive pole each after diode; Export after being connected with self-resetting type element and Temperature protection after each branch road negative pole is connected in parallel.
The beneficial effects of the utility model are; structure is simple and easy to assembling; access battery protection system adds fail safe and the useful life of battery; battery protection system have prevent battery short circuit, overcurrent, cross put, the defencive function such as overheated, charging; can the safe handling of available protecting battery pack, extend the useful life of battery pack.
Accompanying drawing explanation
Fig. 1 is the utility model theory diagram;
Each parts and module numbering in figure:
1-battery pack, 2-diode, 3-self-resetting type element, 4-Temperature protection.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated.
See Fig. 1, primary lithium battery pack with safety system is unified into a branch road with 6 disposable lithium-batteries (WR14505) by cell connector three battery strings, be connected into two branch roads altogether, in battery pack 1, after the series connection of each branch road cell, positive pole is connected with diode 2 respectively, to be connected in parallel output by latter two branch road positive pole of diode 2; Rear output is connected with self-resetting type element 3 and Temperature protection 4 after two branch road negative poles are connected in parallel.
Safety system is the subsidiary safety switch of cell self.
The defencive function of battery protection system is:
The short circuit of battery pack, overcurrent protection.
When the unusual short circuit of battery pack or discharging current are greater than 2A, self-resetting type element 3 resistance increases, and forms open circuit, and battery pack stops electric discharge; When unusual short circuit is eliminated, self-resetting type element 3 recovers normal, and electric discharge continues.
The charging of battery pack, Cross prevention:
When external circuit is to batteries charging, protection component diode 2 is one-way conductions, can stop electric current back through, do not allow external circuit to batteries charging.Battery pack is being let slip in journey excessively; due to the individual difference of cell, can be formed a branch road give another branch road charging situation, now protection component diode 2 also can stop electric current back through; do not allow a branch road to the charging of another branch road, thus ensure the safety of battery pack.
The overheat protector of battery pack:
Battery pack is in discharge process, and when battery pack 1 temperature is greater than 95 DEG C, protection component Temperature protection 4 disconnects, and electric discharge stops.
