High-Voltage Battery - SMART fortwo cabriolet Operator's Manual

Use only charging cables which have been
approved and recommended for the vehicle.
Do not use:
extension chords
R
cable reels
R
multiple sockets
R
travel adapters

When possible, only charge the
high‑voltage battery when the charge
level is below 80 %.
It is recommended to charge the
high‑voltage battery prior to reaching
less than 20% state of charge.
Discharged high‑voltage battery
When the high‑voltage battery is
completely discharged, the drive system is
switched off. This protects the battery
from exhaustive discharge.
i
By switching the ignition off and on
again, the drive system can be briefly
reactivated once. This allows you to park
the vehicle safely.
Do not allow your vehicle to remain
stationary for more than 14 days with a
discharged, or nearly discharged,
high‑voltage battery. You can check the
charge level with the charge level gauge
( page 79).
Y
High or low outside temperatures
The efficiency of the high‑voltage battery
is temperature-dependent and decreases
at high or low temperatures. Additionally,
the electrolytes used can gel at very low
temperatures.
You can check the maximum capacity
available using the indicator in the
multifunction display ( page 83).

Energy consumption and range
The available energy of the high‑voltage
battery is reduced by:
low outside temperatures
R
switching on electrical consumers
R
At low temperatures and after being parked
for an extended period without charging,
the physical properties of the
high‑voltage battery:
can cause a significant reduction in the
R
performance of the battery
can lead to longer charging times
R
In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the
battery is completely charged when
parking the vehicle in low outside
temperatures or for an extended period of
time.
Due to its physical properties, the
capacity of a high‑voltage battery
decreases over its lifespan.
Thus, the following are reduced:
the maximum attainable range of the
R
vehicle
the maximum performance output
R
(acceleration) of the vehicle
You can actively contribute to the
reduction of the vehicle's energy
consumption by:
driving conservatively
R
maintaining the vehicle regularly
R
decreasing the use of electrical
R
consumers
Notes on battery care
Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).
When out of use for longer periods of time,
connect the vehicle to a voltage supply.
If the vehicle is not connected to a voltage
supply, it must remain within a
