An ECU of a fuel cell vehicle determines whether the vehicle travels on an uphill road or not. When determining that the vehicle travels on the uphill road, the ECU performs at least one of a temperature reduction control for reducing the temperature of a fuel cell stack and a humidification control for increasing the water content of the fuel cell stack, by the time the vehicle reaches the uphill road.

A vehicle includes a traction battery and a battery cooling system arranged to cool the battery. A controller of the vehicle is programmed to, responsive to current of the battery exceeding a current threshold and a temperature of the battery being less than a threshold temperature, activate the battery cooling system to cool the battery.

Provided are methods and systems for battery pack thermal management, such as heating and cooling of individual batteries arranged into battery packs. The methods and systems use thermal control modules, specifically configured to thermally couple to the side wall and the bottom end of each battery in a battery pack. In some examples, a thermal control module comprises a thermal plate and one or two battery engagement components, connected and thermally coupled to the thermal plate. Each battery engagement component comprises a plurality of battery receiving openings. When the batteries are installed into these openings, the side wall and the bottom end of each battery are thermally coupled to the thermal control module. Thermal fluid is circulated through at least the thermal plate to provide cooling or heating to the batteries without any direct contact between the thermal fluid and the batteries.

A smart electric temperature-controlled system connected to a vehicle, such as a vehicle-transported refrigeration system, includes a power management system and an energy storage module. The power management system and energy storage module can manage power delivered to the temperature-controlled system components by monitoring temperatures and voltages (and possibly other factors) and by delivering power as a function of the things monitored. In a typical implementation the power management system and an energy storage module can supply power to a vehicle-transported refrigeration system when the vehicle is stopped and/or power from the vehicle electrical system is electrically isolated or otherwise unavailable.
