- the sixth connection terminal 144b6 on the negative side and the negative side The second power supply terminal 146b2 is electrically connected.
- the first heater 102a and the second heater 102b that constitute the first heater unit 100A are connected in series, and the third heater 102c to the sixth heater 102f that constitute the second heater unit 100B. Are connected in series.
- first power source 142A and second power source 142B are connected to the first heater 102a and the second heater 102b constituting the first heater unit 100A, respectively.
- the third heater 102c and the fourth heater 102d constituting the second heater unit 100B are connected in series, connected to the power source (third power source 142C), and the fifth heater 102e and the second heater unit 100B constituting the second heater unit 100B.
- the sixth heater 102f is connected in series and connected to the power supply (fourth power supply 142D).
- the power capacity is 3200 W, for example, 800 W is supplied to the first heater 102 a and the second heater 102 b, 400 W is supplied to the third heater 102 c and the fourth heater 102 d, and 400 W is supplied to the fifth heater 102 e and the sixth heater 102 f, respectively. Assume a case. At this time, if each power supply voltage of the first power supply 142A to the fourth power supply 142D is set to 200V, a current of 4A flows through the first heater 102a to the sixth heater 102f.
- the number of power supplies can be reduced.
- the first power supply 142A and the second power supply 142B are sufficient. For this reason, the wiring route is simplified, and the efficiency of wiring work can be improved.
- the power supply voltage of the first power supply 142A is set to 400V, so that the current flowing through the first heater 102a and the second heater 102b 2A is enough.
- the power supply voltage of the second power supply 142B is set to 400 V in order to apply a voltage of 100 V to the third heater 102c to the sixth heater 102f, the current flowing through the third heater 102c to the sixth heater 102f is increased. 2A is enough. In this way, since the current value can be kept low, the lifetimes of the first heater wire 106a to the sixth heater wire 106f wired to the first heater 102a to the sixth heater 102f can be extended.
- the first heater 102a By the way, for example, when a breakage occurs in the heater wire (first heater wire 106a) of the first heater 102a due to, for example, failure of the unit cell 18 (leakage of active material, etc.) or other causes, in the comparative example, the first heater
- the other second heater 102b to sixth heater 102f function as usual only by the fact that only 102a does not function. Therefore, for example, when a method of feedback controlling the temperature in the box 14 to a constant temperature based on information from a thermometer is adopted, the second heater 102b to the sixth heater 102f except the first heater 102a are used. By increasing the calorific value, the temperature in the box body 14 is maintained constant. In this case, it becomes difficult to detect a failure (such as leakage of active material) of the unit cell 18 and other failures at an early stage.
- the first heater wire 106a or the second heater wire 106b when a break occurs in the heater wire (the first heater wire 106a or the second heater wire 106b) of the first heater 102a or the second heater 102b, the first heater 102a and the second heater 102b.
- the entire first heater unit 100A including the heater 102b does not function. Therefore, it becomes difficult to maintain the temperature in the box 14 at a constant temperature, and based on the decrease in the temperature in the box 14, failure of the cell 18 (leakage of active material, etc.) and other failures are early. Can be detected.
- the wiring route can be simplified, and the efficiency of the wiring work can be improved.
- the life of the heater wire 106 can be extended, and a failure due to the disconnection of the heater wire 106 or a disconnection of the heater wire 106 due to a failure of the unit cell 18 can be detected at an early stage.
- the heater wiring 120 connected to each terminal of the first heater 102a to the sixth heater 102f is connected to a terminal block 140 installed outside the box body 14.
- the first heater 102a and the second heater 102b are connected in series, and the third heater 102c to the sixth heater 102f are connected in series.
- the plurality of heaters 102 connected in series can be arbitrarily selected by simply changing the connection position of the jumper wire 148 connected to the terminal block 140. This eliminates the need for new construction of wiring paths and wiring work, and improves the efficiency of wiring work.
- first heater unit 100A and second heater unit 100B have been mainly described, but the present invention can be easily applied to three or more heater units.
- the battery assembly container according to the present invention is not limited to the above-described embodiment, and can of course have various configurations without departing from the gist of the present invention.
