I01�High-voltage�Components
13.�Operating�Strategy
178
The�operating�strategy�has�the�task�of�maximizing�the�service�life�of�the�high-voltage�battery�and
protecting�it�against�damage�during�operation.�All�customer�requirements�when�driving�and�during
charging�should�also�be�fulfilled.�The�behavior�of�the�electric�motor�in�the�event�of�a�fault�is�also�an
element�of�the�operating�strategy.�The�EDME�is�the�master�control�unit�for�the�operating�strategy.
13.1.�Operating�strategy�with�pure�electric�drive
The�I01�is�designed�as�a�vehicle�with�a�pure�electric�drive�for�urban�mobility.�The�high-voltage�battery
and�the�electrical�machine�deliver�impressive�vehicle�performances:
• Range�>�160 km�(at�20 °C)�/�100�mi�(at�68 °F)
• Maximum�speed�150 km/h/�93�mph�(short-term,�3�minutes)�or�120 km/h/74.5�mph
(continuous)
• Acceleration�from�0-100 km/h�in�7.2�s
Before�a�drive�torque�is�applied,�the�EDME�must�check�whether�the�driving�readiness�is�established.
The�EDME�also�queries�whether�all�subsystems�of�the�electrical�drive�train�are�functioning�trouble-
free,�which�is�also�a�prerequisite�for�the�provision�of�a�drive�torque.�Finally,�the�EDME�still�has�to
consider�the�available�electrical�power�for�the�electric�motor�which�is�primarily�determined�by�the
condition�of�the�high-voltage�battery.�The�SME�control�unit�communicates�this�condition�to�the�EDME
control�unit�via�corresponding�bus�signals.�As�a�result�of�these�checks�the�EDME�identifies�whether
and�in�what�scope�the�drive�torque�can�be�provided.�In�the�case�of�fault�statuses�or�in�the�event�of
limited�availability,�the�EDME�issues�an�appropriate�Check�Control�message�via�the�instrument�cluster.
The�statuses�of�the�operating�strategy�relevant�for�the�customer�and�the�Service�employee�are�listed
below�and�described�briefly.
