Fig. 4 is the control flow chart 400 that battery protection system is carried out under the second mode of operation according to an embodiment of the invention.The second mode of operation refers to that the baseband processor 1214 of battery protection system 100 is operated in anti-theft modes.Below to comprise that the power brick of battery protection system 100 is arranged in electric motor car as example describes.Incorporated by reference to Fig. 1 and Fig. 2, user can pass through terminal equipment, and for example mobile phone, locks battery protection system 100, and discharge switch 160 is disconnected, and disabled user cannot start electric motor car like this, thereby realizes wireless key locking.Once the power brick of this electric motor car is illegally moved; the different base station positional information that background server 206 sends according to battery protection system 100; judge whether to occur illegal movement; once be judged as illegal movement; background server 206 will send instant messages or phone to mobile phone, to carry out alarm to user, user can be processed accordingly; for example user can send to by background server 206 position of the power brick of mobile phone, to help to find the power brick illegally being moved.
Referring to Fig. 1, Fig. 2 and Fig. 4, in step 402, user uses terminal equipment to send locking signal (the 3rd control signal) to baseband processor 1214, and for example, user uses mobile phone to pass through GSM network and radio frequency interface 1216 sends locking signal to baseband processor 1214.In step 404, baseband processor 1214, in response to locking signal, disconnects discharge switch 160, and battery protection system 100 enters anti-theft modes.In step 406, baseband processor 1214 regularly sends the position of power brick to background server 206 according to GSM base station information.In step 408, the position of the power brick that background server 206 sends according to baseband processor 1214, judges whether power brick is illegally moved.For example, the position that background server 206 judges the power brick prestoring is (when baseband processor 1214 disconnects discharge switch 160, send to the position of the power brick of background server 206) whether identical with the position of the power brick receiving from baseband processor 1214, if different, be judged as illegal movement.Once be judged as illegal movement, flow chart 400 enters step 410, otherwise returns to step 406.In step 410, background server 206 sends instant messages or phone to mobile phone, to carry out alarm to user, user can be processed accordingly.
When user need to start electric motor car, user uses mobile phone to pass through GSM network and radio frequency interface 1216 sends start signal to baseband processor 1214, and baseband processor 1214 responds start signal and connects discharge switch 160.
Below to comprise that the power brick of battery protection system 100 is arranged in electric motor car as example describes.Please refer to Fig. 5 and Fig. 6, in step 602, user uses terminal equipment to send locking signal to baseband processor 1214, and for example, user uses mobile phone to pass through GSM network and radio frequency interface 1216 sends locking signal to baseband processor 1214.In step 604, baseband processor 114 keeps conducting charge switch 150 and discharge switch 160, and detects discharging current.In step 606, baseband processor 1214 judges whether discharging current is greater than predetermined threshold value, for example 3 amperes, be greater than predetermined threshold value once be judged as discharging current, and enter step 608, otherwise get back to step 604.In step 608, baseband processor 1214 turn off charge switch 150 and discharge switch 160.In step 610, baseband processor 1214 sends alarm signal to background server 206 by GSM network and radio frequency interface 1216.In step 612, baseband processor 1214 is located power brick according to GSM base station information, and the positional information of power brick is sent to background server 206.In step 614, background server 206 sends instant messages or phone to mobile phone, to carry out alarm to user, user can be processed accordingly.
Obviously, the control flow of Fig. 6 is also applicable to charge switch 150 in the battery protection system 100 shown in Fig. 1 and discharge switch 160 is non-situation about being connected in series.
When user need to start electric motor car, user uses mobile phone to pass through GSM network and radio frequency interface 1216 sends start signal to baseband processor 1214, and baseband processor 1214 responds start signal and connects charge switch 150 and discharge switch 160.
It should be noted that, the concrete control flow that Fig. 3, Fig. 4 and Fig. 6 disclose is as just example.That is to say, the present invention is suitable for other rational control flows or Fig. 3, Fig. 4 and Fig. 6 is carried out to improved step.For example, according to another embodiment of the invention, when power brick is arranged in electric motor car, baseband processor 1214 for example, sends to background server 206 by the data of battery pack 110 (charging current and the discharging current of the voltage of battery, the temperature of battery and battery) by radio frequency interface 1216 and GSM network.Background server 206 is analyzed data message, and storage and show the data message that receives.Therefore; in the use procedure of electric motor car; background server 206 can real-time collecting battery data; the data of collecting not only can be used for data analysis in the future; also can be in the time there is accident in battery; check in time, keep in repair by mobile phone reminding user, have an accident avoiding, reach the object that constantly detects protection for 24 hours.
Again for example, according to another embodiment of the invention, for example, due to the protection threshold value (temperature threshold of battery protection system 100, voltage threshold, current threshold) occur extremely or systems soft ware operation exception, cause the warning information of battery to can not get processing always, the voltage of battery, electric current, temperature maintains outside the scope of protection threshold value always, the performed protection action of system does not occur and tells on, simultaneously also in continuous deterioration, while likely bringing accident hazard, 206 of background servers send the instruction of turn-offing charge switch 150 or discharge switch 160 to baseband processor 1214, baseband processor 1214 is without the data of battery pack and protection threshold value are compared and direct turn off charge switch 150 or discharge switch 160.Background server 206 is notified rapidly user or producer simultaneously, carries out safety inspection, for example, to upgrade parameter (protecting threshold value) or the systems soft ware of system, even whole system is detected to maintenance, accomplishes prevention of accident.
