Summary of the invention
Solve the problems of the technologies described above, the invention provides a kind of cell managing device with fuse, can the various states parameter of on-line real-time measuremen battery pack, communicated with host computer by CAN, and pass through the control mode of CAN control contactor, the remote reboot of battery under guarantee fault mode.
In order to achieve the above object, the technical solution adopted in the present invention is, a kind of cell managing device with fuse, comprise main control unit, DC-DC converter, temperature detecting unit, current detecting unit, voltage detection unit, CAN interface, data storage, fan, charging control contactor, control of discharge contactor and fuse, battery voltage is changed into main control unit operating voltage by described DC-DC converter, described temperature detecting unit, the temperature value of current detecting unit and voltage detection unit difference Real-Time Monitoring battery pack, current value and magnitude of voltage are also sent to main control unit, main control unit is by temperature value, current value and magnitude of voltage are stored to data storage, the order that main control unit is issued by CAN interface Surveillance center, and fan is controlled, realize the adjustment to battery pack temperature, described charging control contactor is connected with main control unit respectively with control of discharge contactor, described fuse and battery power are electrically connected.
Further, this temperature value, current value and magnitude of voltage are uploaded to Surveillance center through CAN interface by main control unit.
Further, temperature detecting unit gathers the cell temperature in battery pack.
Further, voltage detection unit gathers the monomer battery voltage in battery pack, and is sent to main control unit, and main control unit compares the voltage differences between monomer voltage, and calculate average voltage level, thus electric voltage equalization is carried out to the cell in battery pack.
The present invention is by adopting technique scheme, and compared with prior art, tool has the following advantages:
The cell managing device of band fuse of the present invention devises CAN interface, this temperature value, current value and magnitude of voltage are uploaded to Surveillance center through CAN interface by main control unit, and this temperature value, current value and magnitude of voltage are uploaded to Surveillance center through CAN interface by main control unit.Can by main control unit control charging control contactor and the closed of electric discharge contactor controller or disconnection, and when fuse disconnects, instruction is sent to main control unit by host computer, by CAN interface sending controling instruction to main control unit, just can control charge control contactor and the closed of electric discharge contactor controller or disconnection, realize entering normal mode to cell managing device from fault mode, do not need the on-the-spot trouble manually powered on.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention.
Embodiment
Now the present invention is further described with embodiment by reference to the accompanying drawings.
As a specific embodiment, as shown in Figure 1, a kind of cell managing device with fuse, comprises main control unit 1, DC-DC converter 2, temperature detecting unit 3, current detecting unit 4, voltage detection unit 5, CAN interface 6, data storage 7, fan 8, charging control contactor 9, control of discharge contactor 10 and fuse 11, battery voltage is changed into main control unit 1 operating voltage by described DC-DC converter 2, described temperature detecting unit 3, the temperature value of current detecting unit 4 and voltage detection unit 5 difference Real-Time Monitoring battery pack, current value and magnitude of voltage are also sent to main control unit 1, and main control unit 1 is by temperature value, current value and magnitude of voltage are stored to data storage 7, main control unit 1 receives by CAN interface 6 order that Surveillance center issues, and fan 8 is controlled, realize the adjustment to battery pack temperature, described charging control contactor 9 is connected with main control unit 1 respectively with control of discharge contactor 10, and described fuse and battery power are electrically connected.This temperature value, current value and magnitude of voltage are uploaded to Surveillance center through CAN interface 6 by main control unit 1.
Cell temperature in temperature detecting unit 3 pairs of battery pack gathers.Monomer battery voltage in voltage detection unit 5 pairs of battery pack gathers, and is sent to main control unit 1, and main control unit 1 compares the voltage differences between monomer voltage, and calculates average voltage level, thus carries out electric voltage equalization to the cell in battery pack.
The present invention arranges contactor control mode by CAN interface 6, charge/discharge control contactor 9,10 have two kinds of control modes: 1. main control unit controls, and select management devices control mode: main control unit is closed or disconnection according to battery pack situation control contactor; 2. PC control mode is selected: the operating personnel of Surveillance center are by corresponding instruction controlled discharge/charging control contactor 9,10 actions, when charge/discharge current is less than permissible level time, charged/discharged control contactor 9,10 contactor responsing control commands, when charge/discharge current is greater than permissible level time, charged/discharged control contactor 9,10 not response command.
Therefore, after over current fault occurs, cell managing device enters fault mode, charge and discharge control contactor 9,10 all disconnects, after fixing a breakdown, Surveillance center sends instruction to main control unit 1 by CAN interface 6, main control unit 1 could enter normal mode from fault mode, and charge and discharge control contactor 9,10 is closed.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
