Description of drawings
Fig. 1 is the system block diagram that power-supply management system is applied to a battery pack among the embodiment.
Fig. 2 is the structured flowchart of gas detecting module among the embodiment.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing lithium battery of the present invention is described in further detail.
As shown in Figure 1, the power-supply management system 100 of one embodiment of the invention is used for battery pack 200 is carried out voltage monitoring, temperature monitoring, internal resistance monitoring, Balance Control and leakage monitoring, realizes warning function when unusual monitoring battery pack 200.The monitored results of power-supply management system 100 can show by display unit 400.The user also can be connected to a manual controlling platform 300 on the power-supply management system 100, to realize debugging and the control to power-supply management system 100.Display unit 400 can comprise existing various types of displays and LED lamp.Manually controlling platform 300 can be computer, also can only comprise a plurality of control buttons.
Power-supply management system 100 mainly comprises the master control module, is used for a plurality of sub-control module (Fig. 1 neutron control module 1, sub-control module 2 is to sub-control module N) that a plurality of battery units are monitored and gas-monitoring module and radiating module.The gas-monitoring module is used for monitoring by the composition of air in the monitoring battery pack whether leakage takes place in the battery pack.Radiating module is used to battery pack that heat sinking function is provided, and can be fan.
As shown in Figure 2, the gas-monitoring module comprises gas sensor 10, the controller 12 that links to each other with gas sensor 10, and the warning device 14 that links to each other with controller 12.In the present embodiment, gas sensor 10 is a SO 2 sensor.Among other embodiment, can be according to the gas sensor of different battery altering respective type.Warning device 14 comprises light-emitting diode (LED), for example comprises red LED and green LED.Controller 12 is used for sending the leakage signal to the master control module when gas sensor 10 monitors the gas of battery leakage generation, and control warning device 14 sends alarm signal.Concrete, when not detecting sulfur dioxide gas, green LED lamp is bright, on the contrary red LED etc. are bright.Among other embodiment, warning device 14 also can comprise buzzer, when detecting sulfur dioxide gas, and the warning of sounding of controller 12 control buzzers.
Refer again to Fig. 1, the function of a plurality of sub-control modules of power-supply management system 100 is identical with structure.Be that example describes now with sub-control module 1.Sub-control module 1 mainly comprises control unit, the temperature monitoring unit that links to each other with control unit, voltage monitoring unit, Balance Control unit, internal resistance monitoring means and alarm unit.
Temperature monitoring unit, voltage monitoring unit and internal resistance monitoring means are respectively applied for temperature, voltage and the internal resistance of the cell of the corresponding battery unit of monitoring.The Balance Control unit is used under the control of control unit corresponding cell being carried out the balance of voltage.Alarm unit is used to send alarm signal, and this alarm signal can be a light signal, also can be voice signal, also can be light signal and voice signal.Control unit receives the output signal of temperature monitoring unit, voltage monitoring unit and internal resistance monitoring means, judge the operating state of cell in the battery unit according to this output signal, report the running parameter of this battery unit to the master control module, such as but not limited to the internal resistance of the average voltage of this battery unit, mean temperature, cell, and unusual parameter.Control unit can occur sending alarm signal by alarm unit when unusual at battery unit.
In the present embodiment, when control unit judges that difference that the voltage of cell is higher than the battery unit average voltage reaches preset value (for example 0.5V), control Balance Control unit carries out balance of voltage work to the cell of correspondence, so that the voltage of the higher cell of this voltage drops to average voltage.When the temperature of temperature other cells in battery unit of cell when (for example being higher than 1 ℃), control unit control alarm unit sends alarm signal and reports the master control module.Master control module available backup battery unit substitutes this and unusual battery unit occurs, guarantees the safe handling of battery pack.
The master control module is used for according to the signal of each sub-control module and the output of gas monitoring modular battery pack being managed.When certain battery unit occurs when unusual, master control module available backup battery unit is replaced and unusual battery unit occurred, makes unusual battery unit to occur and can be overhauled timely.For example, starting radiating module when the battery pack mean temperature exceeds a preset temperature is the battery pack heat radiation.When the gas-monitoring module monitors arrived the gas of battery leakage generation, leakage appearred in the battery which battery unit is the master control module can judge according to internal resistance of cell parameter, and enabled the reserve battery unit and replace the battery unit that leakage occurs.
To sum up, power-supply management system of the present invention can carry out in real time the various parameters of battery pack, comprehensively monitoring, can realize functions such as battery equilibrium management, radiating management, abnormal alarm, leakage monitoring, reduces the potential safety hazard of battery pack greatly.
Power-supply management system of the present invention is understood the battery that produces gas after being applicable to leakage, for example lithium/thinly chloride (Li/SOCl2), lithium/chlorosulfuric acid (Li/SO2Cl2) and lithium/sulphur primary cell groups such as (Li/S) are specially adapted to be applied to the battery pack of enclosed environment.
