Electric protection voltage, the electricity being charged into and the electricity released offset, that is to say, that the single battery is in the case where filling with electricity
It no longer charges to the single battery, the BMS battery system of battery pack will not act and terminate charging, and charger continues to still
Not up to other single batteries charging of BMS battery system additives for overcharge protection voltage value, in this way, more monomer electricity will be will appear
Cell voltage reaches protection voltage value, and when charging reaches after a certain period of time, every each single battery in battery pack entirely reaches BMS electricity
The additives for overcharge protection voltage of cell system setting, the voltage of each single battery unanimously reaches balanced purpose at this time.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of charging equalization apparatus of the utility model embodiment.
In figure: 1- battery pack, 11- single battery, 2- charge equalizer, 21- discharge resistance, 22- control circuit.
[specific embodiment]
To make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments,
The present invention will be further described in detail.However, it should be understood that specific embodiment described herein is only used to solve
The utility model is released, the range being not intended to limit the utility model.In addition, in the following description, being omitted to known features
With the description of technology, to avoid the concept for unnecessarily obscuring the utility model.
Refering to fig. 1, the utility model embodiment provides a kind of charging equalization apparatus, every in battery pack 1 by several settings
Charge equalizer 2 on a single battery 11 forms, and each charge equalizer 2 is by discharge resistance 21 and control circuit 22
Composition, on-off of the control circuit 22 to control single battery 11 Yu 21 circuit of discharge resistance, and the control electricity
Final voltage value is provided on road 22.
Further, the quantity of the charge equalizer 2 is identical as the quantity of single battery 11, several chargings
Balanced device 2 is corresponded and is connected in parallel with the single battery 11 in battery pack 1, on each charge equalizer 2
Discharge resistance 21 and control circuit 22 are connected in series, and each control circuit 22 also passes through a voltage sample line and connected monomer
Battery 11 connects, with the voltage on the real-time detection single battery 11.
