力を使用することになる。However, as in the above-described structure, when the low temperature state is detected and heated at the ambient temperature of the electric compressor 3, the detected temperature is not the actual temperature inside the compressor.

得ることができる。FIG. 1 is a block diagram showing the configuration of an electric vehicle according to an embodiment of the present invention. A battery 1 is a main battery of an electric vehicle and serves as a driving power source for a vehicle driving motor 2 and an air-conditioning electric compressor 3. Charging means 4
Is for charging the battery 1, and is adapted to be charged by using midnight power when parking at night, for example. During charging, a charging signal 10 is output to the heating means 9 in the inverter 5. At the time of normal air conditioning operation, the inverter 5 outputs the DC voltage from the battery 1,
The switching operation of the switching element group 6 converts the variable voltage into a three-phase PWM AC voltage having a variable frequency and drives the electric compressor 3 at a variable rotation speed. Further, inside the electric compressor 3, there is a temperature detecting means 7 constituted by, for example, a thermistor, a bimetal, a thermocouple thermometer, a pressure thermometer, or the like in order to detect the internal temperature. The temperature of the stator winding 11 is detected and the compressor temperature signal 8
Is output to the heating means 9 in the inverter 5. As for the internal temperature of the electric compressor 3, the same effect can be obtained even if the temperature of the suction port, the discharge port of the compression unit, the lubricating oil, the bearing, etc. is detected.

良い。The heating means 9 receives the charging signal 10 and the compressor temperature signal 8 and, under predetermined conditions, controls the switching element group 6 in a pattern different from that during normal air-conditioning operation to perform electric compression. A voltage is applied so that the motor of the machine 3 does not rotate, electricity is applied, and heating is performed. The energization pattern at this time may be as shown in Japanese Patent Publication No. 4-2859.

０２）。FIG. 2 is a control flowchart in the heating means 9 while the electric compressor 3 is stopped. First, signal 10 during charging
If it is charging, it is determined whether it is being charged. If it is not charging, the battery 1 will be discharged, so heating is stopped (steps 101 and 104). Judge (steps 101, 1)

If it has reached, heating is stopped because it is not necessary to heat it anymore (step 103). , 104), and if not reached, heating is continued (steps 103, 105).

If not, there is no need to heat it (steps 106 and 10
5). By controlling in this way, the electric compressor 3 can be kept warm even when the outside air temperature is low.
When the heating is started, the pressure difference can be made quickly and the blowout temperature can be raised quickly.

The traveling wind hits the compressor, and the detected motor temperature when the temperature detecting means 7 is arranged on the stator winding 11 of the motor inside the electric compressor 3, the actual internal temperature of the compression section, and the heating It is a characteristic view showing the relationship of electric power.

のために余分な加熱電力を消費していることがわかる。As is apparent from FIGS. 3 and 4, when the temperature detecting means 7 is arranged on the surface of the electric compressor 3, the detected compressor surface temperature is affected by traveling wind rather than the compressor internal temperature. Therefore, it can be seen that the internal temperature of the compression unit is different from that of the actual compression unit, and therefore extra heating power is consumed for that.

It is getting bigger.

なくなり、加熱電力も少なくなっていることがわかる。When the temperature detecting means 7 is arranged on the stator winding 11 of the motor inside the electric compressor 3, there is almost no difference between the detected motor temperature and the actual internal temperature of the compression section. It can be seen that the heating power has been reduced.

Generally, when the outside air temperature becomes extremely low (about -10 ° C. or lower), the heating efficiency of the heat pump heating becomes very poor. Since it is equipped with and is switched to it for heating, there is no problem with the heating function.

However, it is possible to prevent the vehicle from stopping.
