wise, the condition of theve hicle's high- volt-
age battery cannot be monitored.
Yo u can contribute toreducing theve hicle's

phase ACcharging is also possible.
Obser vethe di.erent grid requ irements of your
cur rent location when charging. Only use charging
cables which conform tothegr id requiremen ts.
Consult a quali/ed elect rician or your local grid
operator if you ha veany questions.
It is recommended that youch arge the high-volt-
