    摘要: A computer-implemented method of providing optimised future charging plans (70) for charging batteries (91) of electric vehicles (90) of a fleet of electric vehicles (90) using electric vehicle chargers (81). The method comprises the steps of: obtaining respective future travel plans (10) for the electric vehicles (90); obtaining battery data (20) for the batteries (91) of the electric vehicles (90), the battery data (20) including, for each electric vehicle (90), battery state of charge (701, 702, 703) and battery state of health; and executing an optimisation process to determine future charging plans (70) for charging the electric vehicles (90) using the electric vehicle chargers (81), the optimisation process having one or more constraints, including a first constraint that requires the future charging plans (70) to increase the batteries' (91) states of charge to allow the electric vehicles (90) to perform their respective future travel plans (10). Within the one or more constraints, the optimisation process seeks to minimise deterioration rates of the batteries' (91) states of health.

    摘要: A charging system for executing a charging process during a charging frame is provided. The charging system includes one or more electric vehicles (EV) chargers; a load management system (LMS) capable of controlling the one or more EV chargers; a network system comprising one or more wired or wireless connections for linking the one or more EV chargers to the load management system; and a precision-time energy-based control algorithm for dynamically regulating an output power of the one or more EV chargers to meet a preset charging profile. The charging frame is divided into a plurality of sections and the LMS adjusts the output power of each section for compensating an energy shortage in previous sections.
