1. An electric vehicle (EV) power train comprising:

  • a main fast-charging lithium ion module (FC), configured to deliver power to the EV,a supercapacitor-emulating fast-charging lithium ion module (SCeFC), configured to receive power and to deliver power to the EV and/or to the FC,wherein both the FC and the SCeFC have anodes based on a same anode active material,wherein the SCeFC is configured to operate at least at a maximal charging rate of 5 C and within an operation range of 5% at most around a working point of between 60-80% lithiation of the anode active material; and

    a control unit configured to;

    maintain a state of charge (SoC) of the SCeFC within the operation range around the working point,manage the FC and the SCeFC with respect to power delivery to and from the EV, respectively, andmanage power delivery from the SCeFC to the FC and/or to the EV according to specified criteria.
