Summary:

Electric Vehicles (EV) are increasingly becoming more and more popular in the markets, especially in the commercial vehicle segments. Amidst this, the need to find new elegant methods to perform charging of EV battery becomes extremely crucial. In areas with high demand and limited power capacity, performing charging for multiple vehicles necessitates efficient usage of charging infrastructure, which can't be guaranteed by the traditional charging methods. Sequential charging is a new state of art technique for managing the charging of multiple EV's simultaneously connected to a single charging station. Rather than dividing the available power equally among all connected vehicles or charging them one at a time, this technique dynamically allocates power based on various factors such as charging priority, vehicle needs and available infrastructure capacity. Currently, sequential charging can only be implemented by a particular set of chargers that are interconnected via backend and managed by the respective charge point operator aka CPO. In this case, the CPO has limited information about EV fleets. On the other hand, the EV fleet owner does not have any control over the charge scheduling. In this paper, a solution has been provided to allow fleet operators to perform sequential charging from vehicle side wherein, the fleet operator can schedule the vehicle charging based on battery SOC requirements, departure time, vehicle trip plan and several other factors that are otherwise not available to the charger. This is accomplished via its own cloud, independent of the charger. This provides the fleet operator with a greater degree of freedom to optimize vehicle charging. This method also allows multiple vehicles, under a fleet operator, to be connected to different charging stations while still achieving the sequential charging via fleet backend. This technique can be implemented in vehicles adhering to widely used charging standards such as DIN-61851, ISO-15118-2, ISO-15118-20 et cetera
