of time Lithium-ion batteries
experience a natural self-

TE Accelerated ageing of the high-volt-
age battery due tonot observing thefo l-
lowing recommendations As a
result of its basic characteristics, the
storage capacity of and the amount of energy
av ailable from the high-voltage battery
decrease over the course of its life. As a
re sult, the maximum electrical range that can
be achie vedby theve hicle is reduced and its
maximum electrical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R a high le vel of charge , especially if the
ve hicle is idle for a lengt hyperiod of time
R leaving theve hicle idle for lengt hyperiods
at high ambient temp eratures #
