Methods and systems for cooling an electric energy storage device are described. In one example, a temperature set point of a cooling system is reduced before a vehicle reaches a location along a travel route where load on the electric energy storage device is expected to be greater than a threshold load. By lowering the temperature set point, it may be possible to maintain a temperature of the electric energy storage device below a threshold temperature.

Battery thermal preconditioning includes scheduling thermal preconditioning in accordance with user presets, preferences and battery and/or vehicle conditions and profiles. Thermal preconditioning in advance of charging events may optimize charge time, battery health and range. Manual and predictive intelligence methods may be employed to attain and maintain a predetermined range of battery pack temperatures.

A cooling method can be used with an electric vehicle that comprises a vehicle charging connection unit connected to an external cable connected to a charger located outside the electric vehicle, a battery configured to be charged through the vehicle charging connection unit, and a pump configured to circulate cooling water to cool the vehicle charging connection unit. The cooling method includes determining whether an amount of cooling water is insufficient and, upon determining that the amount of cooling water is insufficient, restricting a charging rate of charging power supplied through the vehicle charging connection unit.

A method of controlling scheduled charging is provided. The method includes calculating a primary scheduled charge time based on an expected charge time consumption and an expected primary scheduled charge start time and calculating an expected temperature for the primary scheduled charge time based on the primary scheduled charge time and charger temperature information or climate information. A corrected expected charge time consumption is calculated based on the calculated expected temperature and a secondary scheduled charge time is calculated based on the corrected expected charge time consumption. A vehicle battery is charged based on the secondary scheduled charge time.

The disclosure relates to an eco-friendly vehicle and a method of controlling the eco-friendly vehicle, and optimizing the temperature of the battery of the eco-friendly vehicle towing the vehicle to be towed. The method of controlling the eco-friendly vehicle includes measuring, by a controller, a temperature of a battery during towing driving while a vehicle to be towed is connected, applying, by the controller, the measured battery temperature to a predetermined function to obtain a trend of battery temperature change, predicting, by the controller, a point in time when the temperature of the battery exceeds a predetermined reference temperature based on the trend of battery temperature change, and starting, by the controller, cooling the battery before reaching the predicted excess point.

A system and method for estimating an accumulated total battery aging over different aging patterns. A first aging pattern, first aging time, and aging model are used to determine a battery aging estimation. The aging model, battery aging estimation, and a second aging pattern are used to determine an equivalent previous aging time. By adjusting a second aging time based on the equivalent previous aging time, and applying the adjusted second aging time and second aging pattern to the aging model, a battery accumulated aging estimation is determined for the duration of the first and second aging patterns. The process can be repeated for each next aging pattern, with an equivalent previous aging time being determined for each next aging pattern and used with an associated next aging time, aging model, and next aging pattern to determine an accumulated total battery aging estimation.

In order to provide a gas fueling method capable of suppressing overheating of a tank immediately after a start of fueling, in the gas fueling method, an accumulator and a hydrogen tank are coupled to each other with a gas flow passage. In a main fueling control at and after the timing t2, a sensor-based value MAT of a temperature parameter of a measurement position Q1 is calculated on the basis of a detection value of a first station temperature sensor, and the fueling control is performed on the basis of the sensor-based value MAT. In an initial fueling control at the timing t0 to t2, a prediction value MAT_pred of the temperature parameter is calculated at the timing t2 on the basis of an ambient temperature value, a mass flow rate value, and a heat capacity. The fueling control is performed on the basis of the prediction value MAT_pred.

A vehicle includes an electric-device temperature acquisition unit, a charging controller, and a predicted charging time deriving unit. The electric-device temperature acquisition unit acquires a temperature of an electric device disposed in a current path for external charging for supplying electric power from a power supply external to the vehicle to a battery mounted in the vehicle. The charging controller pauses a supply of electric power to the battery in response to the temperature of the electric device becoming greater than or equal to a first threshold during the external charging, and resumes the supply of electric power to the battery in response to the temperature of the electric device becoming less than a second threshold lower than the first threshold. The predicted charging time deriving unit derives a predicted charging time predicted to be taken for the external charging in accordance with an instruction for the external charging.
