According to the technology disclosed in No. 443, the battery used is a high-temperature operation type (it needs to be maintained at about 350 ° C.).
Since the battery itself can be used as a sufficient heating heat source, the battery has the following five problems. (1) The price of the used Na-S battery itself is expensive. (2) Since the operating temperature of the battery is high, it is necessary to cool the battery at all times during operation. For this reason, a cooling system such as a pump and a fan for constantly cooling the battery is required, and power consumption for operating the cooling system is required. (3) Since the operating temperature of the battery is high, it is necessary to heat it for a long time to reach the operating temperature once it returns to normal temperature. Therefore, for example, the power consumption of the heater for heating the battery is increased. (4) Since the operating temperature of the battery is high, the piping system including the heat exchanger that radiates the battery must be made of heat-resistant materials. Therefore, the cost of the entire system increases. (5) Since the operating temperature of the battery is high, it is necessary to ensure safety against high temperatures in the event of an accident, which also increases the cost of the entire system. Thus, in terms of safety and cost, it is preferable to use a battery whose operating temperature is near normal temperature, instead of a high-temperature operation type battery. However, a battery whose operating temperature is around room temperature has a small amount of heat as a heating heat source, and thus may cause insufficient heating. When a battery whose operating temperature is around room temperature is used, the temperature of the battery decreases in cold regions, the battery capacity and output decrease, and the running distance and acceleration performance of the vehicle decrease. This is a major obstacle to the practical use of electric vehicles that use nearby batteries. If the temperature of the battery is raised more than necessary, the life of the battery is shortened.

When the temperature is high, a technical circuit including a control circuit for dissipating heat generated by the battery and the heat generating member by the heater core is employed.

とができる。When the temperature of the battery detected by the battery temperature detecting sensor is low due to a decrease in the outside air temperature or the like, the battery is heated by the heat generated by the heat generating member by the operation of the control circuit.

Furthermore, when the temperature of the battery detected by the battery temperature detection sensor is high and heating is being performed,
By the operation of the control circuit, excessive heat of the battery and heat generated by the heat generating member are radiated by the heater core. As a result, a rise in the temperature of the battery can be suppressed, a decrease in the battery life can be suppressed, and indoor heating can be performed.

Since the temperature is kept within the proper temperature range, it is possible to prevent a decrease in running distance due to a decrease in battery capacity and a decrease in output of the vehicle. In addition, since a battery whose optimal operating temperature is around room temperature is used for the battery, the disadvantages of the high-temperature operation type disclosed in the prior art (requires constant cooling, it takes time to reach the operating temperature, Etc.). Furthermore, although a battery whose optimum operating temperature is around room temperature is used for the battery, in addition to heating by heat dissipation of the battery during heating, heating is performed using heat generated by a heat generating member, so that the optimum operating temperature is around room temperature. It is possible to eliminate insufficient heating due to only the heat radiation of the battery.

FIG. 1 to FIG. 12 show a first embodiment of the present invention, and FIG. 1 is a schematic configuration diagram of a battery temperature control device. In the electric vehicle, the power of a battery 2 mounted on the vehicle 1 is controlled by an inverter 3 and supplied to a motor 4, and the vehicle 1 is driven by the power generated by the motor 4. This electric vehicle is equipped with a battery temperature control device 5 for keeping the temperature of the battery 2 in an appropriate range. The battery temperature control device 5 of the present embodiment also has a function of suppressing a rise in the temperature of the inverter 3 and the motor 4 as the heat generating member of the present invention. The battery 2 used in the present embodiment has an optimum operating temperature near normal temperature (20 to 7).
5 ° C.) lead-acid battery (Pb-acid battery). Note that the optimum operating temperature is a temperature determined to be optimum in consideration of the main characteristics of the battery 2, such as output, capacity, and life. Then, the lead storage battery used in the present embodiment has a temperature of 20 to 75 ° C. as shown in the correlation graph between the temperature and the life shown in FIG.
Within the range, the life is long, but outside the range, the life is significantly reduced. Then, as shown in the correlation graph between the output and the temperature in FIG. 3 and the correlation graph between the capacity and the temperature in FIG. 4, by setting the minimum use temperature to 20 ° C. or more,
There is no reduction in output or capacity. Also,
In this embodiment, the optimum operating temperature is set to 20 to 75 ° C.
The following are two reasons. As the cold heat source for cooling the battery 2 having heat, outside air is used as described later.
Since the temperature of the outside air is high (about 35 ° C.) in summer, the battery 2 cannot be cooled much. From the result, it is appropriate to set the upper limit of the optimum operating temperature to 75 ° C. Similarly, in a battery 2 such as a lead storage battery whose optimum operating temperature is near normal temperature, the heat generated by the battery 2 itself is not so high. Also, the heat generated by the heat generating members (the inverter 3 and the motor 4) is not so high. Considering these, when used in winter (outside temperature -20 to 0 ° C),
Suitably, the lower limit of the optimal operating temperature is 20 ° C.

Since the heating is performed in step 2, the charging time can be reduced. In addition, when the temperature of the battery 2 is higher than the appropriate temperature during the charging time, such as in summer, the radiator 8 cools the battery 2, so that the charging time can be similarly reduced. At the time of starting, even when the temperature of the battery 2 is lower than the appropriate temperature, the battery is heated by the electric heater 22, so that a decrease in the battery capacity can be prevented, and a decrease in the output of the motor 4 and a decrease in the running distance can be suppressed. be able to. Further, when the temperature of the battery 2 is higher than the appropriate temperature at the time of starting, the battery 2 is cooled by the radiator 8, so that the battery life can be prevented from being shortened. When charging, when the temperature inside the car is low, such as in winter,
When the temperature of the battery 2 rises above the appropriate temperature due to charging, the inside of the vehicle is heated by the heat of the battery 2, so that when the occupant gets on the vehicle 1, the inside of the vehicle is heated to an appropriate temperature.
Further, since the battery 2 is kept warm and stored at an appropriate temperature when charging is completed, in this embodiment, rapid heating can be performed as required by the occupant at the time of starting. Furthermore, when the temperature of the battery 2 rises above an appropriate temperature when the temperature of the inside of the vehicle is low, for example, during traveling of the vehicle, in winter, etc., the inside of the vehicle is heated by the heat of the battery 2, so that electric power for heating is unnecessary, or It can be significantly reduced. Similarly, if the temperature of the inverter 3 or the motor 4 rises when the temperature inside the vehicle is low, the inside of the vehicle is also heated by the heat of the inverter 3 or the motor 4, so that the lack of heating by only the battery 2 in a cold region or the like is compensated. And electric power for heating is unnecessary or can be significantly reduced. Thereby, the power consumed for heating can be reduced, and a decrease in the power of the battery 2 due to heating can be suppressed. As a result, the vehicle traveling distance can be further increased. When heating the battery 2 during running of the vehicle, the electric heater 22 is not used, but the heat released by the motor 4 and the inverter 3 is used, so that a decrease in the power of the battery 2 is suppressed. Since the temperature of the battery 2 is automatically controlled by the control circuit 28 to be within an appropriate range, the appropriate temperature of the battery 2 can be maintained, and the life of the battery 2 can be greatly extended. Since the inverter 3 and the motor 4 are cooled to an appropriate temperature, the inverter 3 and the motor 4
Can be maintained at a high level, and the life of the inverter 3 and the motor 4 can be extended. Since a lead storage battery whose optimum operating temperature is around normal temperature is used as the battery 2, the cost of the battery 2 to be used can be reduced. Since the operating temperature of the battery is near normal temperature, there is no need to constantly cool the battery during operation. For this reason, the power consumption for operating the cooling system is significantly reduced as compared with the case where the high-temperature operation type is used for the battery. Since the operating temperature of the battery is near normal temperature, even if the temperature of the battery 2 returns to the ambient temperature, such as when the vehicle is temporarily stopped,
It takes less time to reach operating temperature. Since the operating temperature of the battery is around room temperature, it is not necessary to form a piping system of a cooling system for radiating heat of the battery 2 with a heat-resistant material, so that costs can be reduced. Since the operating temperature of the battery is around normal temperature, the cost of ensuring safety against high temperatures in the event of an accident can be reduced.
