A charging system charges a plurality of electric vehicles (EVs) simultaneously and allocates available power to associated charging stations. The charging system includes; multiple charging points 2, a first group of power modules 5, second group of power modules 6 and a controller 7. Each power module of the first group is connected to a respective charging point. Each power module of the second group of power modules is switchably connected to any of the charging points. The controller controls the switchable connections between the second group of power modules and the charging points. The controller may receive information about a power demand of an EV connected to one of the charging points and, based on the information, control the switchable connections between the second group of power modules and the charging points. When the power demanded by an EV connected to a charging point exceeds that which can be supplied by one of the first group of power modules, at least one of the second group of power modules may be connected to the charging point. When the power demanded by an EV connected to a charging point does not exceed that which can be supplied by one of the first group of power modules, any power module of the second group that is connected to the charging point may be disconnected.
