1. A method of optimizing utilization of replaceable rechargeable batteries used by a fleet of electric vehicles, comprising:
using at least one processor of a battery management system for:
receiving a travel plan of each of a plurality of electric vehicles of a fleet defining at least a route and a scheduled time of each trip assigned for the respective electric vehicle during a certain time period, each electric vehicle is powered by a set of replaceable rechargeable batteries installed in the respective electric vehicle, each of the replaceable rechargeable batteries is interchangeable between at least some of the plurality of electric vehicles and is rechargeable in each of a plurality of charging sites;
computing a plurality of resources allocation configurations each defining a respective allocation of the plurality of replaceable rechargeable batteries to the plurality of electric vehicles for conducting the plurality of trips defined by the travel plan and charging the replaceable rechargeable batteries at the plurality of charging sites, wherein an electric vehicle arriving at a charging site for service gets its replaceable rechargeable batteries pulled out and replaced with charged replaceable rechargeable batteries;
deriving a plurality of usage scenarios each from a respective one of the plurality of resources allocation configurations, each usage scenario reflects usage and/or recharge of each of the plurality of replaceable rechargeable batteries;
selecting an optimal usage scenario of the plurality of usage scenarios;
computing battery utilization instructions for using and/or recharging each of the plurality of replaceable rechargeable batteries according to the optimal usage scenario; and
transmitting the battery utilization instructions, via at least one network, to the electric vehicles and/or to the charging sites which are configured to conduct the plurality of trips according to the battery utilization instructions expressing the optimal usage scenario to optimize utilization of the plurality of replaceable rechargeable batteries.
