Description
Technical field
The utility model relates to the automatic sync equalizing device of a kind of batteries electric charge, belongs to batteries equalizing charge device technique field.
Background technology
Along with solar photovoltaic generation system is flourish; Energy storage battery VRLA, LI-ION etc. have also obtained using widely; Energy storage battery is widely used in fields such as military affairs, space flight, industrial and agricultural production, telecommunications, electric motor car, owing to voltage, the finite capacity of cell, can not satisfy user's needs; Therefore, usually the series connection of more piece storage battery is used to satisfy the needs of voltage and capacity.Owing to had lack of uniformity by the series connection accumulator internal resistance, when the storage battery series connection is used, can cause the terminal voltage of every batteries in the Battery pack inconsistent, cause the lack of uniformity of accumulator internal resistance more and more serious like this, thereby shortened the useful life of storage battery.Though, more existing in the market can balanced batteries builtin voltage equipment,, these equipment are complex structure not only, when batteries discharges and recharges, can not play the effect of protection to batteries.
The utility model content
The purpose of the utility model is to provide a kind of batteries electric charge automatic sync equalizing device in order to address the above problem; This equalizing charge device adopts independently modularization; Can be complementary with any charging circuit, not receive battery terminal voltage and by the series-connected cell limited in number; Since this equalizing charge device be connected with battery circuit employing passive module cascade again with the storage battery parallel way, thereby can not change the design of original system; This equalizing charge apparatus structure is simple; Volume is little, and production cost is low, and portfolio effect obviously and can realize and charge and discharge and carry out synchronously; Need not that battery pack is carried out the off-line equalizing charge again safeguards; Can improve simultaneously the performance of batteries, prolong the useful life of batteries, be fit to popularize.
In order to achieve the above object, the utility model is realized through following technological means:
The automatic sync equalizing device of a kind of batteries electric charge; It is by partly being made up of source module, pulse regulation parts, pulse generating part, binding post, passive module, energy storage component, bidirectional electronic switch; It is characterized in that: be provided with pulse regulation parts and pulse generating part in the upper end that source module is arranged, have source module to pass through first binding post, second binding post and lead and link to each other with external power source; Left lower end at passive module is provided with the 5th binding post; Upper end at the 5th binding post is connected with energy storage component; Be provided with the 6th binding post in the upper end of energy storage component; Be provided with the 7th binding post on the right of the 6th binding post, be connected with bidirectional electronic switch through lead between the 6th binding post and the 7th binding post, have between source module and the passive module to be connected through the 3rd binding post, the 4th binding post, the 8th binding post, the 9th binding post and lead.
The quantity of described passive module is two at least.
Operation principle
When installing and using; At first; Confirm the quantity of passive module will have source module to be connected according to the quantity of single battery in the battery pack, the 5th binding post on first passive module is connected with the 6th binding post on second passive module with first passive module; The 7th binding post on second passive module links to each other with the positive pole of second single battery; The 5th binding post on last passive module links to each other with the negative pole of last piece single battery, each passive module and last the 8th binding post and the 9th binding post respectively with source module is arranged on the 3rd binding post, the 4th binding post parallelly connected, the automatic sync equalizing device of batteries electric charge this moment installs; Then through having first binding post, second binding post on the source module to be connected the generation pulse signal with external power source; And input to each passive module through the 3rd binding post, the 4th binding post, and when the bidirectional electronic switch conducting on the passive module, positive energy exchange between each monolithic storage battery and its corresponding passive module; When the bidirectional electronic switch on the passive module breaks off; Shift through energy between each passive module of connecting each other, realize balancing energy between the passive module, in next pulse the cycle; During the bidirectional electronic switch conducting; Terminal voltage is higher than the passive module of accumulator voltage to battery charging, and the passive module that terminal voltage is lower than accumulator voltage continues to give this module charging by storage battery, so realizes the equilibrium of battery charge in charging and the discharge condition.
The utility model mainly has following good effect and technical characterictic:
1, this equalizing charge device adopts independently modularization, can be complementary with any charging circuit, does not receive battery terminal voltage and by the series-connected cell limited in number; Since this equalizing charge device be connected with battery circuit employing passive module cascade again with the storage battery parallel way, thereby can not change the design of original system;
2, this equalizing charge apparatus structure is simple; Volume is little, and production cost is low, and portfolio effect obviously and can realize and charge and discharge and carry out synchronously; Need not that battery pack is carried out the off-line equalizing charge again safeguards; Can improve simultaneously the performance of batteries, prolong the useful life of batteries, be fit to popularize.
