A battery temperature adjusting device for a vehicle on which a battery is mounted, the battery being a lithium ion battery disposed near a powertrain unit inside an engine bay, is provided. The device includes a first air duct provided to an intake passage configured to lead intake air to a combustion chamber of an engine, a second air duct provided to the intake passage and provided with an intake opening that opens toward a space between the powertrain unit and the battery, an intake-air-amount adjusting part, and a controller configured to acquire an ambient temperature of the powertrain unit. The controller increases a ratio of the second intake air amount relative to the sum of the first intake air amount and the second intake air amount, when the ambient temperature exceeds a first threshold temperature, compared with when the ambient temperature is below the first threshold temperature.

A vehicle battery cooling system includes a battery temperature sensor, a vehicle cabin temperature sensor, a discharge path via which a vehicle cabin, a battery chamber, and outside of a vehicle communicate with each other, a circulation path that circulates air between the vehicle cabin and the battery chamber, a switching unit that switches between the discharge path and the circulation path, and a controller. When a pressurization condition is satisfied, the controller operates the switching unit to select one of the discharge path and the circulation path based on measurement results of the battery temperature sensor and the vehicle cabin temperature sensor. The pressurization condition includes a condition that an air pressure in the vehicle cabin is higher than atmospheric pressure. When temperature of a battery is in a low cooling range and is higher than temperature in the vehicle cabin, the controller selects the discharge path.

A cabinet with anti-condensation mechanism is used to control opening and closing a cabinet door of the cabinet. The cabinet includes a control module, a temperature control module, and a locking module. The control module senses a cabinet-inside temperature inside the cabinet, and senses cabinet-outside temperature and a cabinet-outside humidity outside the cabinet to generate a dew-point threshold value. The temperature control module is used to adjust the cabinet-inside temperature. The locking module is used to lock the cabinet door or unlock the cabinet door. The control module controls the locking module according to the cabinet-inside temperature and the dew-point threshold value, and controls the temperature control module to adjust the cabinet-inside temperature to be greater than or equal to the dew-point threshold value when the control module receives a trigger signal.

A battery temperature regulating apparatus includes an onboard battery, a temperature regulating plate, a heat exchanger including a container and a first internal passage, first to third passages, a radiator, a valve, a temperature sensor, and a control device including a processor and a memory. The processor is configured to execute, in cooperation with a program included in the memory, a process including determining whether a temperature of the onboard battery is higher than an upper threshold of a proper temperature range, determining whether a heat source is in the container at least based on the temperature of a first heat medium detected by the temperature sensor, and if the temperature of the onboard battery is higher than the upper threshold and that the heat source is in the container, controlling the valve in such a way as to allow the first heat medium to flow through the heat exchanger.

A battery cooling system includes a cooling fan that takes in inside air of a vehicle cabin to an intake passage and sends the air to a battery communicating with the vehicle cabin through the intake passage, a battery temperature sensor that detects a temperature of the battery, an intake air temperature sensor that is disposed in the intake passage and detects a temperature of the air flowing through the intake passage, and a controller. The controller controls the cooling fan based on the detected temperatures. The controller performs a temperature check operation. Firstly, when the difference value between the detected temperatures is larger than zero, the controller repeats the temperature check operation. Afterward, When the difference value in the latest temperature check operation is smaller than the difference value in the previous temperature check operation and larger than zero, the controller repeats the temperature check operation.

A method of determining a preconditioning status of a vehicle component or system.

The method includes receiving a preconditioning status request for a vehicle component or system;

determining the preconditioning status by a preconditioning model estimating the preconditioning status without activating the corresponding vehicle component or system.

A battery pack thermal management system includes a first circulation line in which a first refrigerant temperature-increased while passing through an electronic sub-assembly passes by a first control valve, dissipates heat in a first heat exchanger, and circulates back to the electronic sub-assembly, a second circulation line in which a second refrigerant circulates through a battery pack, a compressor, and a condenser in this order or through the condenser, the compressor, and the battery pack in this order, and a plurality of valves controlling a flow path along which the second refrigerant flows in the second circulation line. The plurality of valves are capable of temperature-increasing or cooling the battery pack by controlling a flow path along which the second refrigerant flows.
