A control system (100) for a traction battery (1000) in an electrically powered vehicle. The control system (100) is configured to: receive a journey start time (102) indicative of a time at which the traction battery will be used to power the vehicle; calculate, using the journey start time (102), and in dependence on a target battery charge level (104) and a target battery operating temperature range (106), a charging start time (108) at which to start charging of the traction battery (1000) to: charge the traction battery toward the target battery charge level by the journey start time; and heat the traction battery, due to charging of the traction battery, toward a temperature within the target battery operating temperature range, by the journey start time; and output the determined charging start time (108).
