Then, to charge power supply with euqalizing current respectively to each batteries charge situation, that is, equalizaing charge pattern carry out
Explanation.
When the voltage of certain batteries is less than the battery (referred to as maximum voltage battery) in other batteries with maximum voltage
Voltage, and institute's low degree more than the first preset ratio when, for example, battery bt4 has maximum voltage (for example, in each batteries
3.2v), the voltage (for example, 2.5v) of battery bt1, now, the voltage of battery bt1 is less than the voltage of maximum voltage battery bt4
Degree be (3.2-2.5)/3.2 ≈ 22%, if setting the first preset ratio be 20%, this degree already exceed first preset
Ratio, illustrates now there is such battery (i.e. battery bt1), and its voltage is less than the degree of the voltage of maximum voltage battery relatively
Greatly, if now adjusting voltage difference between two cell voltages (i.e. battery bt1 and battery bt4) not in time away from this gap may
Expand further, or, this gap will lead to two batteries cannot finally simultaneously or nearly be simultaneously filled with.For this reason, work as there is certain
One battery, when its voltage is less than the degree of the maximum voltage of other batteries more than the first preset ratio, ON-OFF control circuit makes this
Corresponding switching device of battery (in this example embodiment for corresponding switching device ss1 of battery bt1) connection is so that this switch
The corresponding secondary windings of device (secondary windings for being numbered between 3,4 in this example embodiment) are with euqalizing current (i.e. euqalizing current
I1 it is) that this battery bt1 charges.
It should be noted that the process being corresponding battery charging with euqalizing current (i1, i2, i3 or i4) in secondary windings
In, pulse switch device ps is according to pulse signal cycle ground on or off.In order to provide pulse to pulse switch device ps
Signal, can arrange pulse control circuit, this pulse control circuit and on-off control electricity in multigroup equalizing charge of battery manager
Road connects.When ON-OFF control circuit judges a certain battery, the degree that its voltage is less than the maximum voltage of other batteries exceedes
During the first preset ratio, ON-OFF control circuit marker pulse control circuit sends pulse signal, and this pulse signal is used for controlling arteries and veins
Rush switching device ps periodically on or off.It should be noted that, although battery balanced being filled with multigroup in this embodiment
Illustrate as a example setting pulse control circuit in electric manager, however, in another concrete implementation mode, Pulse Width Control electricity
Road can be arranged independent of this multigroup equalizing charge of battery manager.In addition, though in this embodiment with pulse control circuit
Illustrate as a example being connected with ON-OFF control circuit, however, in another concrete implementation mode, pulse control circuit can with open
Close control circuit to realize by processor together.
As described above, when the voltage that the voltage finding a certain battery is less than maximum voltage battery exceedes to a certain degree
When (i.e. the first preset ratio), just secondary switching device accordingly is opened, so that equalizer transformer t is filled for this battery with euqalizing current
Electricity.So, while being charged by principal current i0, this batteries is also charged by euqalizing current (i1, i2, i3 or i4), because
This, its total charging current is bigger compared to other batteries, and the charge rate of therefore this batteries is higher, can make this batteries
Quickly charge, thus gradually evening up the voltage/electricity gap between this batteries and maximum voltage battery.
The voltage of the battery being charged with euqalizing current by corresponding secondary windings when this reaches maximum voltage battery
During voltage (when being flattened), or, it is less than the second preset ratio (e.g., less than less than the degree of the voltage of maximum voltage battery
5%), when, ON-OFF control circuit makes corresponding switching device of this secondary windings turn off so that this secondary windings stops equalizing
Electric current charges for this battery, to prevent from overcharging.
Here, illustrating to euqalizing current.Euqalizing current is that charge power supply is passed through equalizer transformer t and filled respectively for battery
The electric current of electricity.Equalizer transformer t is a power less transformator, actual design for the general power of charge power supply
When be the 10%～15% of charge power supply general power.Equalizer transformer t simply plays in multigroup equalizing charge of battery manager
The effect of voltage/electricity fine setting.It is i1, i2, i3, i4 respectively with each batteries bt1, bt2, the corresponding euqalizing current of bt3, bt4
As a example illustrate.In this utility model, can by adjust pulse signal dutycycle arrange euqalizing current i1, i2, i3,
The size of i4.
So that the voltage that the voltage of single battery is less than maximum voltage battery exceedes to a certain degree as a example enter in the above description
Row explanation, however, in this utility model, when the voltage of two or three batteries is less than the voltage of maximum voltage battery more than one
When determining degree, ON-OFF control circuit can open corresponding two or three switching device simultaneously, makes equalizer transformer t to equalize
Electric current is that this two or three battery charges.
From the foregoing, it will be observed that compared in prior art, after certain batteries is full of, stopping principal current is to each batteries of connecting
Charge, so that this batteries being filled is discharged to equal with other battery electric quantities, be then then turned on principal current, lead to this batteries
Life-span be shortened, in this utility model, whole charging process will not carry out passive electric discharge, every batteries all only have
Charging process, thus battery life will be led to be shortened because of passive electric discharge.
In addition, mentioning in the above description, when battery that voltage reaches rated voltage occurs, main switching device ms can be made
Turn off, so that charge power supply stops with principal current i0, series battery being charged.However, except reaching rated voltage
Battery outside, other batteries not yet reach rated voltage, still need to continue charge.For this reason, ON-OFF control circuit can control to remove reaching
Secondary switching device corresponding to other batteries to outside the battery of rated voltage is opened, and makes equalizer transformer t with euqalizing current
Charge for these batteries.Further, after certain batteries of original underfill are full of by euqalizing current, ON-OFF control circuit connects
Control corresponding switching device of this battery to turn off, and corresponding switching device of the battery of remaining underfill keeps opening
Open, so that equalizer transformer t is charged for remaining battery with euqalizing current, until all batteries are each filled with.
In addition, in the above description, mentioning equalizer transformer t is the 10% of charge power supply general power in actual design
～15% power, this refer to when 4 secondary windings of equalizer transformer t and its corresponding each switching device ss1, ss2,
When ss3, ss4 are in conducting state, the corresponding power of each secondary windings.When only one secondary windings and its corresponding each time
When switching device is in the conduction state, this secondary windings is 4 times that the power that corresponding battery charges can reach above-mentioned power,
That is, 40%～60%, this is because now only one secondary windings turn on, other 3 secondary windings do not consume (dividing to walk)
Any power.In this case, the battery that can make this underfill is more rapidly evened up and maximum voltage battery between
Gap.
As described above, the multigroup equalizing charge of battery manager being provided according to this utility model, become due to employing equilibrium
Depressor t and its setting of corresponding branch road, and control is opened and closed away from degree based on the voltage difference between battery, therefore, it is possible to
Improve equilibrium precision, further, it is possible to guarantee that every batteries are filled with, or even tend to being simultaneously filled with.
In a more specific implementation of above-described embodiment, in order to according to the degree of heat of battery to principal current
It is controlled, battery temperature testing circuit can be set in multigroup equalizing charge of battery manager, for measuring each batteries
Temperature.This battery temperature testing circuit is connected with ON-OFF control circuit.When ON-OFF control circuit is according to battery temperature testing circuit
When detecting that the temperature of each batteries obtaining determines that the temperature of a certain battery is too high, for example, when exceeding preset temperature, on-off control
Circuit can control main switching device ms and turns off, so that charge power supply stops with principal current i0, series battery being filled
Electricity.Meanwhile, ON-OFF control circuit can control time switching device ss1, ss2, ss3, ss4 and controls pulse by pulse control circuit
Switching device ps is so that equalizer transformer t is that other batteries in addition to the higher battery of the degree of heat fill with euqalizing current
Electricity.It should be noted that, although in this embodiment with setting battery temperature detection electricity in multigroup equalizing charge of battery manager
Illustrate as a example road, however, in another concrete implementation mode, battery temperature testing circuit can be independent of this many Battery pack
Equalizaing charge manager and arrange.
