Equalisation Charging; Charging Times - MG ZS EV Owner's Manual

Starting & Driving

Equalisation Charging

Equalisation charging means that after
a normal charging process the battery
management system will enter a mode where
it will attempt to equalise the charge of every
battery cell.
If an equalisation charge has not been carried
out for some time, the message centre in the
instrument pack will display 'Please Slow-
charge the Vehicle'. Please refer to 'Slow
Charging' in the 'Starting and Driving' section.
On average it takes at least 8.5 hours
to complete a charge that includes the
equalisation charge.
Note: Ambient temperatures have an
effect on charging times. It may take
longer to complete a charge when the
ambient temperatures are low.

Charging Times

Charging times of the high voltage battery can
vary depending upon numerous factors, these
include: current capacity, charging mode,
ambient temperature and device type/power.
Rapid Charging Time
Rapid chargers will vary in power output,
on average it will take approximately 40 - 60
minutes to charge the high voltage battery
up to 80% (80% displayed in IPK) using an
average rapid charger.
Note: Ambient temperatures have an
effect on charging times. It may take
longer to complete a charge when the
ambient temperatures are low or high.
Slow Charging Time
On average it takes approximately 8 hours
to charge the high voltage battery from low
battery warning to 100% (charge quantity can
be checked using the instrument pack).
• At low temperatures the charging time
will be extended.
• If an equalisation charge has not been
conducted for a long time the required
charge time will be extended.
• An equalisation charge must be carried
out prior to using the car after a long
period of storage or non use. In these
cases the charging time will be extended.
Note: The slow charging notes above
relate to using an AC charging device.
Use of the slow charging device using a
domestic power supply can increase the
charging times by up to 3 times.
