Abstract
The utility model discloses a transfer protection system for battery equilibrium energy, comprising a main chip, an energy transfer device and a battery gating switch, wherein in a charging process, the main chip continuously scans and monitors the voltage of each battery to be charged; and when the highest battery voltage and the lowest battery voltage are detected to achieve a certain voltage difference, an energy transfer power supply switch is opened, and energy power supplementation is carried out on the battery with low voltage by controlling the battery gating switch. Compared with theprior art, the utility model has the advantages that the energy transfer efficiency is high, repeated charging and discharging in the charging process of the battery are avoided, the working life of the battery is prolonged, and all the batteries in a battery pack can be basically realized to be charged to a set value for one time.
Description
[technical field]
The utility model relates to battery power supply system, relates more specifically to battery balanced energy transfer system.
[background technology]
Existing balancing technique all belongs to the energy dissipation formula, just in one group of non-equilibrium battery pack, if when finding high and low-capacity batteries, can forward the high-capacity battery energy the high energy content of battery to low-capacity batteries in through components and parts such as inductance, diodes this moment, therefore can cause high energy battery to consume to some extent.In addition, the method of work that inductance that above-mentioned technology adopts and diode energy shift only limits to the transmission of energy between the adjacent cell, go here and there many Battery packs groups in charging process as 10, as find B10 capacity height, and the B1 capacity is low, prior art can only forward B9 to from B10, forward B8 again to, and the like to B1 because energy can not directly forward B1 to from B10 effectively, cause power conversion limited and efficient is low.
When the rechargeable battery complete charge; stopping energy shifting; thereby limited energy and shifted the effect that can not once reach balance; such as: in the non-equilibrium batteries charging process of 10 strings; the B10 capacity is higher; because B10 has reached full state; circuit carries out over-charge protective and stops charging; if shift the B10 energy this moment, promptly B10 can produce discharging current, thereby the discharge time of increase B10 influences the use cycle-index of battery; thereby do not influencing under the battery life situation; can only stop energy and shift, so batteries charging can not reach the battery equilibrium effect after once finishing, can only just can reach the final counterbalance effect of battery by repeatedly discharging and recharging.
In view of above drawback, be necessary to provide a kind of new battery balanced energy to shift protection system in fact to overcome above-mentioned defective.
[utility model content]
Main purpose of the present utility model is to provide a kind of energy transfer efficiency height, reliably a kind of battery balanced energy of balanced energy to shift protection system.
For achieving the above object, the utility model adopts following technical scheme: a kind of battery balanced energy shifts protection system, it comprises master chip, mend electric main power source, the battery gating switch, and wherein, described master chip constantly carries out each cell voltage scanning monitoring to be charged in charging process; When the highest cell voltage and minimum cell voltage reach the certain voltage difference in detecting battery pack, open the switch of mending electric main power source, charge by the battery of control battery gating switch to low-voltage.
The electric main power source of described benefit is constant current constant voltage output in charging process.Battery balanced energy shifts protection system and also is provided with state-of-charge indicator, LED battery indicator.
Described battery balanced energy shifts protection system and also is provided with discharge detection circuit, and discharge detection circuit detects discharging current when excessive, and master chip just can be controlled the discharge on-off switch so that stop discharge.
After the battery of described ceiling voltage was full of electricity, master chip continued the switch that electric main power source is mended in control, can battery charge to all batteries of other low-voltage be full of.
Compared to prior art, the utlity model has following advantage:
1. energy transfer efficiency height;
2. avoid battery repeated charge in the process of charging, the working life that prolongs battery;
3. all battery charge in the disposable realization battery pack of basic energy are to set point.
[description of drawings]
Fig. 1 is the circuit theory diagrams that a kind of battery balanced energy of the utility model shifts protection system.
[embodiment]
Please refer to shown in Figure 1ly, be the basic structure of the utility model preferred embodiment.A kind of battery balanced energy of the utility model shifts protection system 100, and it comprises master chip 10, mends electric main power source 20, battery gating switch 30, state-of-charge indicator 40, LED battery indicator 50 and discharge detection circuit 60.
When any cell overcharges, master chip 10 just stops charging by 70 pairs of whole battery group of control charge switch, but because the charger output voltage is not controlled, so master chip 10 continues the switch of the electric main power source 20 of control benefit low battery is mended, mend set point up to all batteries, this moment, charging finished, and promptly battery balanced energy shifts and finishes.
During discharge, discharge detection circuit 60 has detected discharging current, and master chip 10 enters discharge mode, and LED battery indicator 50 is indicated minimum battery electric quantity, and indicates the current electric sequence number of mending by state, represents the present electric weight of this battery minimum.If it is excessive that discharge detection circuit 60 detects discharging current, reach set point or greater than limiting value, or when master chip 10 detected voltages and reaches the discharge minimum safe limit in the discharge process, master chip 10 realized stopping discharge by control discharge on-off switch 80.
A kind of battery balanced energy of the utility model shifts protection system; be not restricted to described in specification and the execution mode; for those skilled in the art, can easily realize additional advantage and modification; therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the examples shown that the utility model is not limited to specific details, representational equipment and illustrates here and describe.
