Method of and system for priority management of the state of charge (SoC) of a battery and one or more fluid temperatures of an electric work vehicle while the vehicle is connected to a charging module. A duration of immobilisation (based on the expected time of the vehicle’s return to use, 110), a target fluid temperature 120, target SoC 130, minimum charge duration, and minimum time required for adjusting the fluid temperature are used to determine a charging start time 150 and a heat exchange start time 160 based on a priority decision 140. The priority decision is made such that the fluid temperature and the SoC are between a threshold value and a target value at the return to work time, and the charging speed remains below a threshold. The length of time required for heating may be calculated based on the initial temperature, target temperature, heat input value, and volume of the fluid. The temperature of a plurality of fluids may be adjusted using a single coolant circuit or a plurality of coolant circuits. The fluid may be a hydraulic fluid, battery coolant, HVAC fluid, or motor or inverter coolant.
