PROBLEM TO BE SOLVED: To provide a cooling control device for an internal combustion engine, capable of appropriately setting the operation time of an electric water pump for checking water temperature. SOLUTION: The cooling control device for the internal combustion engine cools by circulating the cooling water by the electric water pump. A heat quantity estimation means estimates the heat quantity of the internal combustion engine at the time of previous trip and an operation time changing means changes the operation time of the electric water pump for checking the temperature of the cooling water (water temperature check) on start-up based on the estimated heat quantity of the internal combustion engine. For example, the smaller the heat quantity is, the shorter the operation time is set. Thus, the operation time of the electric water pump for checking the water temperature on start-up can be appropriately shortened. Hence, wasteful operation of the electric water pump can be suppressed, power consumption can be reduced and thermal diffusion can be prevented. COPYRIGHT: (C)2010,JPO&INPIT

SOLUTION: A power supply controller controls the supply of power to a capacitor in a vehicle 10 equipped with a motor 14 functioning as a source of power and the capacitor 13 which functions as a power supply for the motor and stores electric power at least by being supplied with power using electromagnetic waves supplied from an external power supply 1. The power supply controller is equipped with a setting means 21 for setting an amount of power to be supplied relating to the supply of power before a vehicle enters a region wherein it is supplied with electromagnetic waves; and power supplying means 11, 12 which receive electromagnetic waves supplied when the vehicle travels in the region and supplies power to the capacitor by using the received electromagnetic waves based on the set amount of power to be supplied.

PROBLEM TO BE SOLVED: To provide a cooling water controller of an internal combustion engine promoting the warmup of the internal combustion engine, sufficiently recovering exhaust heat, and suppressing the boiling of cooling water. SOLUTION: This cooling water controller comprises: a cooling water passage circulating between the internal combustion engine; an exhaust heat recovery device and a heater core; a bypassing passage; a flow distribution means; and a control means. The bypass passage is connected to the cooling water passage, and bypasses the internal combustion engine. The flow distribution means distributes the flow of the cooling water between a water jacket in the internal combustion engine and the bypass passage. The control means changes the ratio of the flow of the cooling water in the water jacket inside the internal combustion engine to the flow of the cooling water in the bypass passage. The warmup of the internal combustion engine is thereby promoted, the exhaust heat in the exhaust heat recovering device is sufficiently recovered, and the boiling of the cooling water is suppressed.

PROBLEM TO BE SOLVED: To suppress the deterioration of emission and fuel consumption as much as possible in a cooling device. SOLUTION: The position of the valve element of a first three-way valve 350 is controlled to a position where the circulating supply of cooling water through a branched flow path 310c is blocked when an engine 200 is operated and when the engine 200 is stopped and heating request is not made in a vehicle 10. When the engine 200 is stopped and heating request is made, heating mode during stoppage is carried out. In the mode, the position of the valve element of the first three-way valve 350 is controlled to the position of the valve element where the circulating supply of the cooling water through the branched flow path 310c is carried out, and simultaneously a first motor-driven W/P320 is stopped, so that the cooling of the engine 200 is stopped. Accordingly, heat recovered with a waste heat recovering device 500 is supplied to a heater core 420, and heating is efficiently carried out, and the deterioration of the fuel consumption and the emission is suppressed when the engine 200 is restarted.

PROBLEM TO BE SOLVED: To provide a battery temperature conditioning device capable of preferentially heating a battery cell arranged at both ends at the time of warming up. SOLUTION: The battery temperature conditioning device has a housing case and battery cells. The battery cells are arranged in the housing case at prescribed spacings. Passages in which a temperature conditioning medium flows are formed between the battery cells and between the battery cell and the inner wall of the housing case. The direction in which the battery cells are arranged and the direction (flowing direction) in which the temperature conditioning medium flows into the housing case are perpendicular. Further, the temperature conditioning medium flowing part supplies the temperature conditioning medium flowed into the housing case into the passages adjacent to the battery cells at both the ends in the arrangement direction out of a plurality of passages. Thereby, the battery temperature conditioning device warms up the battery cells at both the ends positively and preferentially. COPYRIGHT: (C)2010,JPO&INPIT
