13.2.￿Operating￿strategy￿for￿vehicles￿with￿range￿extender
Using￿the￿optional￿range￿extender￿it￿is￿possible￿to￿extend￿the￿range￿of￿the￿I01.￿The￿W20￿combustion
engine￿drives￿the￿range￿extender￿electrical￿machine,￿whereby￿electrical￿energy￿is￿generated.￿This
electrical￿energy￿flows￿directly￿to￿the￿electric￿motor/electrical￿machine￿or￿to￿the￿high-voltage￿battery
depending￿on￿the￿driving￿requirement￿(the￿EME￿decides￿the￿flow).￿The￿aim￿is￿to￿keep￿the￿state￿of
charge￿(SOC)￿at￿a￿constant￿level.
