Circuit charging and voltage stabilizing device 105 includes: at least one management module 110.Each management module 110 to Rechargeable battery
Corresponding one or more battery is electrically connected in parallel in 100, and is charged when foreign current is applied to battery core pack, surely
Pressure pipe reason.Management module 110 includes: voltage stabilization unit 111, shunts enable unit 112, at least one shunting enhancement unit
120。
For example, in Fig. 1, loop circuit charging and voltage stabilizing device 105 includes 3 management modules 110, each management module
It include two shunting enhancement units 120 in 110；The positive T1 and cathode T2 of battery core pack can be electrically connected to external power supply and from
External power supply and obtain foreign current.But the present invention is not limited by above-mentioned example.It, can be according to practical application such as when realizing
Demand, or increase under the parameter of parameters such as the quantity of battery, the demand of pressure stabilizing or foreign current maximum value in such as battery core pack
Few management module that adds deduct and the quantity for shunting enhancement unit；In configuration, a management module can be used to manage one
A management module can be used also to manage the battery of two or more serial or parallel connections in battery.
For example, battery core pack includes multiple concatenated Rechargeable batteries 100, and Rechargeable battery 100 can be

Voltage be not allowed to foreign current and continue growing and avoid the generation of unsafe condition.In addition, flowing to charged electric
Foreign current other than pond 100 can continue on for the purposes of the charging of other batteries in battery core pack.When all in battery core pack
The voltage of battery be all stabilized to corresponding predetermined value (such as voltage threshold value), i.e., when pressure stabilizing balances, it is believed that battery core pack
It is filled full or is completely filled；Even if battery core pack is given in the application that foreign current continues, most foreign current all passes through loop circuit
Charging and voltage stabilizing device 105 and the situation for avoiding battery core pack from overcharging, and can avoid the surging of foreign current to battery core pack
It damages.
In other words, charging, pressure stabilizing management of the loop circuit charging and voltage stabilizing device 105 to battery core pack keeps battery core pack whole
It is upper with the imitative characteristic that can reach pressure stabilizing voltage limit thereon such as prior art lead-acid battery.For example, if battery core pack
Rechargeable battery 100 be lithium ion battery, then loop circuit charging and voltage stabilizing device 105 can be such that battery core pack further has
Pressure stabilizing can be reached in the characteristic of upper limit voltage, to enable battery core pack safely applied to the traffic of various equipment such as automobile
In tool.In addition, loop circuit charging and voltage stabilizing device according to the present invention can also be applied to have multiple concatenated lead-acid batteries
