Brief description
Fig. 1 is the structure chart of the function of temperature control detection means of the sodium-sulfur battery management unit of one of the present invention；
Fig. 2 is the flow chart of the method carrying out function of temperature control detection using function of temperature control detection means of the two of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, sodium-sulfur battery management unit includes: mutually corresponding three couveuse heater plate loops defeated
Enter and hold b5, b6, b7, outfan b8, b9, the b10 in three couveuse heater plate loops, and three temperature of heating plate measurements
Terminal.B1-b4 is the power supply port of bmu heating circuit.The function of temperature control detection of the sodium-sulfur battery management unit of the present invention
Device, including host computer (not shown), three bulbs l1, l2, l3 and three K-types thermocouple t1, t2, t3, wherein,
Three bulbs l1, l2, l3 be connected to three couveuse heater plate loops input b5, b6, b7 and
Between outfan b8, b9, the b10 in three couveuse heater plate loops, to emulate couveuse heating plate.In the present embodiment,
The power of bulb l1, l2, l3 is 40 watts.
Three K-types thermocouple t1, t2, t3 are connected to three temperature of heating plate measurement terminal, for collecting temperature.
The operation principle of bmu temperature controlling function is the temperature of K-type thermocouple is the judgement whether corresponding couveuse heating plate power supply is connected
Index, when temperature K-type thermocouple is detected is less than setting temperature, this road power supply corresponding should be connected, and otherwise disconnects.Three
Individual bulb l1, l2, l3 and three K-types thermocouple t1, t2, t3 correspond.
Host computer connects sodium-sulfur battery management unit (bmu), host computer preset temperature threshold value (generally greater than room temperature 15-20
℃).When certain K-type thermocouple t1, t2 or t3 institute collecting temperature is less than default temperature threshold, sodium-sulfur battery management unit will
