Abstract: A method of priority management of an electric work vehicle while the electric work vehicle is connected to a charging module. A duration of immobilization, a target temperature, a target state of charge, a minimum rise duration and a minimum charge duration are used to determine a charging start time (160) and a heat exchange start time (150) based on a time priority decision (140). The time priority decision (140) is made such that the actual temperature of the first fluid is between the threshold temperature and the target temperature at the anticipated fluid usage time; an actual state of charge is between the threshold state of charge and the target state of charge at the anticipated start time; and an actual charge speed is below a threshold charge speed.
