F3DM –Dual Mode EV
DM stands for Dual Mode: EV + HEV
Basically an Electric Vehicle (EV), with an engine as backup for long distance drive (i.e. HEV) In EV mode, driving range can be over 100Km , plus 380Km in HEV mode
Fe Battery , perfect for EV; BHS , an advanced technology integrating generator and motor controls
Household sockets can be used for recharging, independent of special charge facilities
