    Abstract: A voltage detection circuit detects the voltage of a plurality of serially connected cells in a power storage unit. The voltage detection circuit receives a supply of a power supply voltage from both ends of the plurality of cells. A DC-DC converter converts the voltage between both ends of the plurality of cells into another DC voltage. An adjustment circuit adjusts the power consumption of the plurality of cells. The adjustment circuit operates using the DC voltage generated by the DC-DC converter as the power supply voltage.

  • Publication number: 20180180061
    Abstract: A motor-driven compressor includes collars, which maintain the gap between a cover and an outer surface of a first housing member. Fasteners fasten the cover to the first housing member. Each collar is arranged to face a seating surface of the head of the corresponding fastener such that the cover is sandwiched between the collars and the seating surfaces. Each collar thus includes a facing portion, which faces the seating surface and receives a pressing force from the seating surface via the cover, and a transmitting portion, which transmits the pressing force received at the facing portion to a base member. Accordingly, the pressing force applied through the seating surface of the fastener is transmitted to the base member through the collar, so that the base member is pressed against the outer surface of the first housing member.

  • Patent number: 9995302
    Abstract: A motor-driven compressor includes an electric motor, a drive circuit, a modulation method controller, a temperature measuring section, a high-temperature (HT) stop controller, and a high-temperature (HT) stop temperature setting section. The high-temperature (HT) stop controller stops the electric motor when the temperature measured by the temperature measuring section is higher than or equal to a predetermined high-temperature (HT) stop temperature. When the modulation method is the three-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a three-phase high-temperature (HT) stop temperature. When the modulation method is the two-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a two-phase high-temperature (HT) stop temperature, which is higher than the three-phase HT stop temperature.

  • Patent number: 9964111
    Abstract: A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a temperature threshold. The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold from the first temperature threshold to the second temperature threshold when the control unit activates a field weakening control that reduces counter electromotive force generated by the electric motor.
