6.￿Charging￿the￿High-voltage￿Battery
Although￿AC￿charging￿with￿3.7 kW￿is￿standard￿equipment￿in￿many￿countries￿in￿the￿US￿market,￿it￿only
refers￿to￿the￿charging￿via￿the￿occasional￿use￿cable￿(inserted￿into￿a￿normal￿110V￿socket).￿The￿big
advantage￿of￿this￿charging￿option￿is￿that￿for￿charging￿the￿high-voltage￿battery￿the￿charging￿cable￿can
be￿connected￿at￿any￿household￿power￿socket￿with￿protective￿contact.￿However,￿the￿current￿level￿for
charging￿is￿also￿restricted￿to￿a￿maximum￿16￿A.￿The￿maximum￿charging￿power￿is,￿for￿example￿for￿supply
at￿AC￿voltage￿network￿in￿Germany,￿3680 W￿(P￿=￿U￿x￿I￿=￿230 V￿x￿16 A).￿The￿total￿time￿it￿takes￿to￿fully
charge￿a￿discharged￿high-voltage￿battery￿of￿the￿I01￿(storable￿energy:￿18.8 kW￿net)￿would￿be￿about￿7
hours.￿In￿order￿to￿reduce￿the￿use￿of￿the￿maximum￿charging￿power￿for￿houses,￿a￿charging￿procedure￿is
never￿performed￿at￿maximum￿charge￿current.￿Therefore,￿the￿actual￿charging￿time￿is￿longer.
The￿EME￿is￿designed￿so￿it￿can￿provide￿a￿maximum￿electrical￿power￿of￿3.7 kW￿on￿the￿output
side.￿This￿is￿charging￿configuration￿is￿used￿(in￿the￿US￿market)￿only￿when￿charging￿with￿the
occasional￿use￿cable￿via￿a￿household￿120￿V￿socket.￿And￿it￿sufficient￿to￿fully￿charge￿the￿I01
high-voltage￿battery￿under￿optimal￿marginal￿conditions￿in￿about￿16￿hours.
