• «No battery» function (not recommended):
This function allows you to use the SHOWROOM power mode when there is no battery. To do this, press
the START/STOP button for 3 seconds. The «No battery mode» indication is displayed for 3 seconds
before forcing the power supply.
It is strongly recommended not to use the «no battery» function if a battery is present.
This function disables the «Integrated charging» function, as well as some of the protections such as
abnormal undervoltage protection or disconnection detection.
In this configuration, reverse polarity can damage the vehicle electronics.
• «Integrated charging» function:
The SHOWROOM mode (outside of the «no battery» function) incorporates an automatic charging algorithm adapted to all types
of batteries (lead and lithium), in order to guarantee an optimal charge level for demonstration vehicles. This function is perfectly
compatible with the presence of consumers on the battery.

Analysis Charging
Step 1: Analysis
Analysis of the battery condition (charge level, inversion, etc.)
polarity, wrong battery connected, etc).
Step 2: Charging
Fast charging at maximum current until U1 is reached
(ex: 13.8 V to )
Step 3: Absorption
Charge under constant voltage U1 (ex: 13.8 V in
