A kind of large capacity single body battery
Technical field
The utility model relates to a kind of large capacity single body battery.
Background technology
Lithium battery has specific capacity high, and specific power is large, has extended cycle life, and free of contamination advantage, obtained increasing application again.From little to mobile phone, toy for children, arrive greatly portable power tool, electric bicycle, and battery-operated motor cycle, until electric automobile has application.
But this battery is used organic electrolyte, and its conductive capability is far below the aqueous solution.In order to improve the ability of its electric current output, the polar plate area of design is very large, and as thin as a wafer, the carrying capacity of active matter is extremely low for thickness.The battery pole plates area that capacity is little is just very large, is difficult to make, and battery manufacture difficulty capacious is just larger.And electrode area is larger, more easily bring manufacturing deficiency and unbalanced into.It self occurs that the probability of quality problems and safety problem is just from far away higher than small-capacity cells.
The production small-capacity cells all be take as main in general factory, because the application of small-capacity cells is more extensive.So the production technology of small-capacity cells is more smart better, consistency is higher, and mass defect is lower.
Large capacity single body battery volume is large, and the electric current passed through is large, and the heat of generation is many, but its heat-sinking capability is more much lower than small-capacity cells.So its temperature rise will be far away higher than baby battery.The life-span of the infringement battery that the high temperature meeting is serious.
Above known, there is following shortcoming in large capacity single body battery:
1, large capacity single body battery is easily brought more manufacturing defect aborning into, and the probability gone wrong in use is large.
2, the production technology of large capacity single body battery is superior not as baby battery, and the consistency of product is poor.
3, large capacity single body battery heat-sinking capability is poor, and battery temperature rises higher.
4, the large capacity single body energy content of battery is large, just in case safety problem occurred, its destructive power is large, dangerous large, wayward.
Summary of the invention
The purpose of this utility model is to provide that a kind of reliability is high, the large capacity single body battery of failure rate is low, good heat dissipation effect.
For reaching the goal of the invention the technical solution adopted in the utility model, be:
A kind of large capacity single body battery, it is characterized in that: comprise the cylindrical cell of a plurality of low capacities, the like pole of the cylindrical cell of a plurality of described low capacity passes through respectively metal connecting sheet, and be unified into large capacity single body battery, the positive and negative end of described large capacity single body battery is fixed by plastic clamp, described large capacity single body battery is equipped with conducting strip in gap, the cylindrical cell surface of shell contact of the described low capacity of the Jun Yuqi both sides, two sides of described conducting strip, an end of described conducting strip is exposed at outside the outline line of large capacity single body battery.
Further, described conducting strip is to be arranged in the gap of large capacity single body battery along X-axis or Z-direction.
Perhaps, described conducting strip is that X-axis and Z-direction are arranged in a crossed manner in the gap of large capacity single body battery, forms the heat transfer network.
Further, the two ends up and down of described conducting strip are installed in plastic clamp.
Technical conceive of the present utility model is by a plurality of better quality with plastic clamp, the performance more two ends up and down of the cylindrical cell of low capacity of homogeneous is fixed, with brace, like pole is connected in parallel and forms large capacity single body battery, the capacity of large capacity single body battery equals the cylindrical cell capacity of each low capacity in parallel sum, and its voltage is equivalent to a battery.Can, according to the requirement of output voltage, by several large capacity single body battery series connection, form the battery pack of target voltage.Insert conducting strip in the gap of large capacity single body battery, the housing contacts of they and the cylindrical cell of each low capacity, these conducting strips reach outside the outline line of large capacity single body battery, with the end conducting strip conducting strip that these are parallel, be connected in parallel from the outside again, become the closed-loop path of a heat transfer sheet at large capacity single body battery appearance, the heat of large capacity single body battery is transmitted on peripheral fin by each conducting strip.Conducting strip of the present utility model also can X-axis and Z-direction arranged in a crossed manner, form the heat transfer network, make the surrounding of the cylindrical cell of each low capacity that conducting strip be arranged, radiating effect can be better.
Large capacity single body battery described in the utility model only need to be drawn a voltage signal line to protective circuit in use, just can realize the operating voltage monitoring to this battery.
The beneficial effects of the utility model:
1,, with the cylindrical cell of low capacity and be unified into large capacity single body battery, because the quality of the cylindrical cell of low capacity is high, the failure rate of large capacity single body battery is descended greatly.
2, in large capacity single body battery, indivedual cylindrical cells of low capacity go wrong, and General Influence, less than other batteries, also can be easy to change, and the reliability of whole large capacity single body battery has improved.
3, the mass defect of the cylindrical cell of low capacity is few, is not easy to occur security incident.Even there is a battery out of joint, its destructive power is little, is not easy to spread to other batteries, easily processes.The fail safe of large capacity single body battery improves greatly like this.
4, insert conducting strip in the gap of large capacity single body battery equipotential plane, it contacts with cell wall, heat easily transmits out, heat passes to the end conducting strip, it has entered surrounding space, and heat radiation easily, can make the temperature of large capacity single body battery obviously descend, especially use heat transfer meshes, can use battery temperature in large capacity single body battery to reach unanimity.
5, after having used heat transfer sheet, reduce the working temperature of large capacity single body battery, can effectively extend the useful life of battery.
6, heat transfer sheet is simple in structure, is easy to processing.Because being is inserted between equipotential row, the plastic clamp isolation is arranged up and down, do not need insulation.
