1. A method of managing an energy storage system (ESS) of a vehicle, said energy storage system having a beginning of life (BOL), said vehicle having at least a first application and a second application, said energy storage system having a first end of life (EOL1) for said first application and a second end of life (EOL2) for said second application, said ESS having a first lifetime between said BOL and said EOL1 and a second lifetime between said BOL and said EOL2, said method comprising the steps of:
a) determining energy and/or power requirement for said vehicle being in said first application;
b) defining energy and/or power of said energy storage system at the beginning of life (BOL) of said energy storage system of said vehicle;
c) determining a first state of health value SOH1 at the first end of life (EOL1) of said energy storage system of said vehicle being in said first application;
d) determining energy and/or power requirement for said vehicle being in said second application;
e) determining a second state of health value SOH2 at the second end of life (EOL2) of said energy storage system if said vehicle is used in said second application;
f) communicating said SOH1 and/or said SOH2 of said ESS to the driver of said vehicle;
g) suggesting to the driver said first or said second application for said vehicle such that said lifetime of said energy storage system is maximized by choosing the application giving the highest SOH value.
