Description
Technical field
This utility model relates to a kind of charging system, particularly to the direct balancing charging apparatus of a kind of rechargeable battery set.
Background technology
Battery power supply is the electric power source that power supply is supplied to relevant electronic installation, and be applied to supply unit can
To be the set of cells (multicellbattery) with multiple battery.Owing to using set of cells, rather than single battery
Relation, can apply high voltage, or increase capacity.But, because battery itself has the characteristic of discharge and recharge, the voltage meeting of each battery
Change over time and become uneven.Voltage difference between battery in battery pack may produce the imbalance between battery, thus
The capacity of consume set of cells.About this, existing many battery balancing systems and method are to balance each battery, it is to avoid all batteries
Overcharge, and equilibrium charging.
Having a kind of method in prior art, it allows electric current to flow to set of cells high voltage appearance battery by resistance etc., to adjust
Whole battery equilibrium.Although the method is completely simple, but it has a shortcoming, if the most unbalanced high-voltage battery increases, can increase
Add discharge current and heat can be produced.In addition, the further drawback of the method is, in all batteries of set of cells, balances quilt
It is adjusted to the battery with minimum voltage value.In addition, a kind of permission charging current is had to flow through low-voltage battery in set of cells
With the method adjusting balance.The method uses DC-to-DC converter, and its advantage is that efficiency is the highest, and produces
Heat energy little.
But, the method also has a shortcoming, if i.e. low-voltage number of batteries increase time, whole set of cells battery electricity
The minimum voltage pressing meeting more original than it is the lowest.And, when reading the voltage of each battery, because reading the relation of time difference, read
To voltage between can produce the biggest difference.Owing to voltage reads the difference of time, battery balancing system can determine whether that battery is
Unbalanced.The time read according to each cell voltage, there is difference in magnitude of voltage, especially uses circuit in lithium ion battery
Device is selected to adjust the device of the balance of voltage.In existing battery equilibrium adjusting apparatus, when being loaded into electricity by load device
During stream, the electrode voltage (ternimal voltage) of battery can change along with the change being loaded into electric current.Bearing of load device
As time goes on load can change.Therefore, when reading the electrode voltage of battery, and passed through line selecting device and existed
When central processing unit compares, even if the voltage of all batteries actually balance, still can read the electricity of each battery respectively
Pole tension value.So, central processing unit can determine whether that each battery is uneven, and then output balance control signal is to control balance
Electric current control zone.When in battery balancing system, when reading cell terminal voltage by line voltage selecting device, if loaded
Electric current does not the most change, then can find that cell terminal voltage is also not changed in.Therefore, central processing unit can determine whether battery
The voltage of electrode is balance.But, when load current varies, cell terminal voltage also can change.Therefore, when being loaded into electric current
When changing in real time, central processing unit can determine whether that the electrode voltage of battery is to become uneven, brings because changing over time
Load change result in voltage reading difference.Like this, line selecting device is used to read the electrode of battery when central processing unit
During voltage, owing to the time selecting battery electrode is different, the cell terminal voltage read may be different.
Accordingly, it would be desirable to a kind of battery balancing system or method, it can reduce reading cell voltage in battery system
Error, is performed quickly the balance of voltage, and increases the accuracy of the balance of voltage.
According to prior art, battery balancing system has various condition and limits.For example, only do not have in system itself
The balance of voltage just can be carried out during running.The relation limited due to these, voltage balancing operation becomes complicated, and it is unnecessary to consume
Time, and the accuracy of the balance of voltage can be reduced.
