Abstract
The utility model designs a cycle life protecting circuit of a storage battery, which mainly comprises the storage battery and a charging controller. A general charging circuit is connected with the storage battery through the charging controller; the charging controller is connected with a micro charging lithium battery; and a comparator for comparing the voltages of the general charging circuit, the micro charging lithium battery and the storage battery is arranged in the charging controller. According to the cycle life protecting circuit of the storage battery, the micro charging lithium battery is arranged in the charging circuit and provides micro charging current under the condition that the general charging circuit does not work; and micro charging current provided by the micro charging lithium battery can be used for effectively suppressing the crystallizing phenomenon in the storage battery, thereby the cycle changing life of the storage battery is prolonged and further the service life of the storage battery is prolonged. Meanwhile, by reasonably designing the voltage relationship between the storage battery and the micro charging lithium battery, the cost of the lithium battery is reduced; by using the characteristics of the lithium battery with longer life and no memory effects, the use cost of the storage battery is reduced; and the cycle life protecting circuit is especially suitable for the storage battery in a solar charging system.
Description
Technical field
The utility model relates to a kind of protective circuit, particularly a kind of battery cycle life protective circuit.
Background technology
Storage battery of the prior art generally all is a battery, it recycles the deep discharge that shorter main cause of life-span is storage battery, cause internal storage battery to form a large amount of lead sulfates, can't be reduced into lead oxide by charging after the lead sulfate crystallization and make the actual capacity of storage battery descend.On the other hand, along with the application of the various new forms of energy of progress of society is popularized gradually, wherein the main energy storage device that uses is exactly a storage battery in the application of solar energy, and the solar energy use is subjected to the influence of weather bigger, occur rainy weather under the certain situation continuously, make storage battery can't obtain charging for a long time, solar facilities itself has certain micro-electric consumption again, make storage battery the situation of little current discharge occur, further have influence on the life-span that recycles of storage battery.
The utility model content
The purpose of this utility model is to provide a kind of circuit structure simple for the deficiency that solves above-mentioned technology, can effectively protect storage battery to recycle the battery cycle life protective circuit in life-span.
In order to achieve the above object; the battery cycle life protective circuit that the utility model is designed; it mainly comprises storage battery and charge controller; generally be connected with storage battery by charge controller towards circuit; charge controller is connected with little towards lithium battery, is provided with more general towards circuit, little comparator towards lithium battery and battery tension in the charge controller.The characteristics of sort circuit are in the non-loaded situation of non-charging, by being the flow discharge for what fill lithium battery, storage battery are carried out the maintainability charging, thus the interior crystalline polamer of containment storage battery.
In order further to protect the life-span of storage battery, described little output voltage towards lithium battery is 120%95% of a storage battery output voltage.By reasonable configuration storage battery and little voltage relationship, littlely under situation as much as possible, work maintenance free cell towards lithium battery towards lithium battery.
The resulting battery cycle life protective circuit of the utility model; in charging circuit, be provided with little towards lithium battery; general towards circuit not under the working condition; provide little towards electric current; its the little interior crystalline polamer that can effectively contain storage battery towards electric current; thereby prolong the cycle charging life-span of storage battery, and then prolong the useful life of storage battery.Simultaneously owing to designed rational storage battery and little voltage relationship between lithium battery, reduce the cost of lithium battery, utilization has the lithium battery life-span longer, and the characteristics that do not have memory effect, make the use cost of storage battery reduce, be particularly suitable for using on the storage battery in solar recharging system.
Description of drawings
Fig. 1 is an electrical block diagram of the present utility model;
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As Fig. 1; the storage battery 1 cycle life protective circuit that present embodiment is described; it mainly comprises storage battery 1 and charge controller 2; generally be connected with storage battery 1 by charge controller 2 towards circuit 3; charge controller 2 is connected with little towards lithium battery 4, is provided with more general towards circuit 3, little comparator 5 towards lithium battery 4 and storage battery 1 voltage in the charge controller 2.And described little output voltage towards lithium battery 4 is 120% of storage battery 1 output voltage.
During use, the comparator 5 in the charge controller 2 is more general towards circuit 3, little voltage towards lithium battery 4 and storage battery 1, when general when circuit 3 has charging voltage, give earlier little towards lithium battery 4 chargings, treat little be full of towards lithium battery 4 after, accumulators 1 charges again.When circuit 3 does not have charging voltage, little when general towards the little current discharge of lithium battery 4 beginnings, storage battery 1 is carried out trick charge.
Claims (2)
1. battery cycle life protective circuit; it mainly comprises storage battery and charge controller; generally be connected with storage battery by charge controller towards circuit; it is little towards lithium battery to it is characterized in that described charge controller is connected with, and is provided with more general towards circuit, little comparator towards lithium battery and battery tension in the charge controller.
2. battery cycle life protective circuit according to claim 1 is characterized in that described little output voltage towards lithium battery is the 120%-95% of storage battery output voltage.
