Development of efficient air-cooling strategies for lithium-ion battery module based on empirical heat source model

A controller of a thermal management system for a vehicle controls a first switching valve and a second switching valve to set a battery warming-up state in which a heat medium circulates between a battery-temperature adjustment heat exchanger and a heat-medium heating heat exchanger, and the heat medium does not circulate between a coolant-coolant heat exchanger and a heat-medium heating heat exchanger when both a battery and an engine need to be warmed up. In contrast, the controller controls the first switching valve and the second switching valve to set an engine warming-up state in which the heat medium circulates through between the coolant-coolant heat exchanger and the heat-medium heating heat exchanger while the heat medium does not circulate between a battery-temperature adjustment heat exchanger and the heat-medium heating heat exchanger when a temperature of the battery exceeds a target battery warming-up temperature in the battery warming-up state.

Provided is a compact inverter-integrated electric compressor which has good mountability and heat resistance reliability and enables reductions in vibration and noise. Specifically provided is an inverter-integrated electric compressor (1) in which an inverter device comprising a noise elimination filter circuit and an inverter circuit is incorporated into an inverter accommodation portion (9) provided at the outer periphery of a housing (2). The inverter accommodation portion (9) is provided at the outer periphery of the housing (2) and configured from an inverter box (10) in which the inverter circuit is accommodated and installed, and a junction box (11) which is integrally joined to the inverter box (10) and in which the components of the noise elimination filter circuit are accommodated and installed. The junction box (11) is joined to the inverter box (10) with the inner spaces thereof facing each other, and also serves as the cover of the inverter box (10). The noise elimination filter circuit and the inverter circuit are electrically connected.

The present invention is to drive a hydraulic pump (12) and a generator motor (13) by an engine (10), electrically charge a battery (20) by a generator operation of the generator motor (13), and assist the engine (10) through driving the generator motor (13) by electric power of the battery (20). On the premise of the configuration above, when a deviation between a target rotation speed of the engine and an actual rotation speed of the engine is equal to or more than a preset value, and when a residual amount of fuel is equal to or less than a preset value, it is considered to be engine failure or an operation state which is directly connected to the engine failure and an engine assisting action is automatically stopped.

Hybrid working machine

A rear seat is foldable by moving downward a seat cushion and folding forward a seat back. A power source unit is disposed below a rear floor to the rear of the rear seat. When the rear seat is in an unfolded state, cooling air can be introduced from inside a vehicle compartment, through a space between a lower surface of the seat cushion and an upper surface of an underseat floor, into a cooling-air introduction port in the power source unit. When the rear seat is in a folded state, the cooling air is introduced from inside the vehicle compartment, through cooling-air introduction passages, into the cooling-air introduction port. Thus, the power source unit can be cooled irrespective of whether the rear seat is in the folded state, without reducing the foldability of the rear seat.

Electrical device cooling structure in vehicle

A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.

PROBLEM TO BE SOLVED: To effectively cool electric equipment mounted behind a rear seat, without impairment of a folding function of the rear seat. SOLUTION: The rear seat 16 can be folded by moving a seat cushion 14 downward and falling a seat back 15 forward. A power supply unit 19 is disposed under a rear part floor 27 behind the rear seat. When the rear seat 16 is in a non-folded state, cooling air can be induced from a vehicular cabin into a cooling air inducing port 34 of the power supply unit 19 through a space between a lower surface of the seat cushion 14 and an upper surface of a floor 21 under the seat. When the rear seat 16 is in a folded state, cooling air can be induced from the vehicular cabin into the cooling air inducing port 34 through cooling air inducing passages P1, P2. Therefore, the power supply unit 19 can be cooled regardless of a folding state of the rear seat 16. COPYRIGHT: (C)2007,JPO&INPIT
