Abstract
A charging method of a lithium battery pack is characterized in that a lithium battery pack required charging is in parallel connection with a high-capacity lithium battery pack of which voltage is different from the former; due to the voltage difference, the energy in the high-capacity lithium battery pack can be transferred to the lithium battery pack to realize charging of the lithium battery pack. The method has the benefits that the charging speed is quick, the efficiency is high and the reliability is high.
Description
Technical field
The present invention relates to a kind of charging method of lithium battery group.
Background technology
The charging method of existing battery pack is all generally to adopt charger to charge, and the charging interval of this charging method is longer, and efficiency is low, and very wastes energy.
Summary of the invention
The object of the present invention is to provide a kind of charging method of short, efficiency is high, reliability is high battery pack consuming time.
For reaching goal of the invention the technical solution used in the present invention, be:
A kind of charging method of lithium battery group, it is characterized in that: will need the lithium battery group of charging and receive on the high-capacity lithium battery group different from its voltage, owing to there being voltage difference, the energy of high-capacity lithium battery group can be transferred in the lithium battery group, and the lithium battery group is charged.
Further, when the lithium battery group equates with the voltage of high-capacity lithium battery group, by the high-capacity lithium battery group is charged, be charged to the constant voltage section, complete the lithium battery group is charged fully.
Further, described high-capacity lithium battery group and lithium battery group between be provided with a PTC element or current limiting element.
Further, the capacity of described high-capacity lithium battery group is more than 2 times of lithium battery pool-size.
Further, described high-capacity lithium battery group can be charged to the lithium battery group more than 2 simultaneously.
Technical conceive of the present invention is by pressure reduction, the energy lithium transfer battery pack of high-capacity lithium battery group to be charged to the lithium battery group, i.e. environmental protection is practical again, and charging rate is fast, and reliability is high.In order to prevent that initial current is excessive, the lithium battery group is caused damage, between high-capacity lithium battery group and lithium battery group, be provided with a PTC element or low resistance current limiting element.
Beneficial effect of the present invention: charging rate is fast, and efficiency is high, and reliability is high.
The accompanying drawing explanation
Fig. 1 theory diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is further described, but does not limit the invention to these embodiments.One skilled in the art would recognize that the present invention contained all alternatives, improvement project and the equivalents that may comprise in claims scope.
With reference to Fig. 1, a kind of charging method of lithium battery group, by the lithium battery group 1 of needs chargings and receive on the high-capacity lithium battery group 2 different from its voltage, owing to there being voltage difference, the energy of high-capacity lithium battery group 2 can be transferred in lithium battery group 1, and lithium battery group 1 is charged.
When lithium battery group 1 equates with the voltage of high-capacity lithium battery group 2, by high-capacity lithium battery group 2 and connect 3 pairs of high-capacity lithium battery groups 2 of a charger and charge, be charged to the constant voltage section, complete lithium battery group 1 is charged fully.
Between described high-capacity lithium battery group 2 and lithium battery group 1, be provided with a PTC element or current limiting element 4.
The capacity of described high-capacity lithium battery group 2 is more than 2 times of lithium battery group 1 capacity.
Described high-capacity lithium battery group 2 can be charged to the lithium battery group 1 more than 2 simultaneously.
Technical conceive of the present invention is by pressure reduction, 1 pair of lithium battery group 1 of energy lithium transfer battery pack of high-capacity lithium battery group 2 to be charged, i.e. environmental protection is practical again, and charging rate is fast, and reliability is high.In order to prevent that initial current is excessive, lithium battery group 1 is caused damage, between high-capacity lithium battery group 2 and lithium battery group 1, be provided with a PTC element or low resistance current limiting element 4.
