Electro-mobility is increasing significantly in the urban public transport and continues to face important challenges. Electric bus fleets require high performance extended longevity of lithium-ion battery at highly variable temperature different operating conditions. On other hand, operators are more concerned about reducing operation maintenance costs, which affects aging cost represents a significant economic parameter for deployment electric fleets. This paper introduces methodological approach manage overnight charging an fleet. identifies optimal strategy that minimizes (the replacing spread over lifetime). The optimization constraints related conditions, vehicle supply equipment, power grid. evaluates fitness function through coupled modeling electro-thermal properties batteries. Simulation results indicate reduction capacity loss 10 years compared three typical strategies.
