1. A method, comprising:
receiving data about a low voltage distribution network including a distribution transformer, the data on the low voltage distribution network including a power rating for the distribution transformer;
receiving telematics data from each of a plurality of electric vehicles (EVs);
determining a forecast of usage for each of the EVs;
estimating a level of degradation of the low voltage distribution network from the forecast usage for each of the EVs and from the data on the low voltage distribution network; and
determining from the telematics data, from the data on the low voltage distribution network, and from the estimated level of degradation of the low voltage distribution network a corresponding schedule for charging each of the plurality of EVs through the distribution transformer such that a total amount of power supplied through the distribution transformer when all of the plurality of EVs are charging according to the determined schedules does not exceed a limit for the low voltage distribution transformer.
