Abstract: A vehicle charging system to be applied to an electric vehicle includes a rectifier, an inverter, first and second relays, and a control processor. The rectifier is disposed on a charging path. The inverter is disposed on a first power feeding path. The first and second relays are respectively disposed on the charging path and a second power feeding path. The control processor performs control that allows for: contactless charging via the charging path from external equipment; and first power feeding to an external device via the charging path and the first power feeding path from the external equipment, or second power feeding to the external device via the second power feeding path from the external equipment. The control processor controls operation states of the relays in accordance with power being supplied from the external equipment, power requested at a battery, and power necessary at the external device.

Abstract: A charging prediction system includes vehicles, a charging station, and a control device including one or more processors and one or more memories. The one or more processors are configured to execute a process. The process includes accumulating, in a storage device, record data that is actual data on a charged vehicle ratio for a first remaining traveling distance of each of the vehicles traveling along a specific traveling road. The process includes deriving, based on the record data, a predicted value of the charged vehicle ratio for each vehicle in a predetermined group including ones of the vehicles currently traveling along the specific traveling road. The process includes deriving a predicted waiting period that is a predicted value of a waiting period to a start of charging at the charging station based on the predicted values of the charged vehicle ratios.

Abstract: A vehicle includes a battery pack, an air conditioning system, a communication member, a pack humidity detector, an outside air humidity detector, and a controller. The battery pack contains a battery module. The air conditioning system is configured to regulate humidity of air and send the air. The communication member fluidly connects a blowing port of the air conditioning system and an inside of the battery pack. The pack humidity detector is configured to detect humidity in the inside of the battery pack. The outside air humidity detector is configured to detect humidity of an outside air. The controller is configured to control the air conditioning system so that the humidity in the battery pack is equal to or lower than the humidity of the outside air.

Abstract: A battery temperature control apparatus includes: a high voltage battery installed in a vehicle; a low voltage battery installed in the vehicle; a first temperature control system configured to adjust a temperature of the low voltage battery using air supplied from outside the vehicle; and a second temperature control system that is different from the first temperature control system and configured to adjust a temperature of the high voltage battery using a heat medium circulating within the vehicle. The second temperature control system includes: a first heat exchanger configured to exchange heat between the high voltage battery and the heat medium; and a second heat exchanger configured to exchange heat between the low voltage battery and the heat medium. The temperature of the low voltage battery is adjustable using the heat medium supplied to the second heat exchanger.

Abstract: A vehicle heat management system includes a refrigerant circuit, a battery temperature regulation circuit, and an electric part cooling circuit. The refrigerant circuit circulates a refrigerant to regulate a temperature inside a passenger compartment through the refrigerant circuit. The battery temperature regulation circuit regulates a temperature of a battery by introducing a liquid that exchanges heat with the refrigerant to the battery. The electric part cooling circuit circulates a liquid cooled by a radiator circulates through the electric part cooling circuit, and is capable of cooling a first and second pieces for driving a vehicle. In a first mode, the liquid cooled by the radiator cools the first piece of equipment, the refrigerant of the refrigerant circuit cools the second piece of equipment, and the liquid which has exchanged heat with the refrigerant is introduced in parallel to the battery and the second piece of equipment.
