User Manual JUICE BOOSTER 2 [EL-JB2, EA-JB2] version 1.07 EN 25
HOT
(G)
Charger is overheating. Stop the charging process at the vehicle.
Allow the JUICE BOOSTER 2 to cool
down.
In the event of a fault, the device will also
cool itself down automatically and restart
the charging process as soon as the
device temperature has dropped
sufficiently. Do not expose the device to
strong direct sunlight.
Known problems with the Renault Zoe vehicle, especially models with 43 kW charger. Request a
technical update at your garage in order to resolve these problems:
LED glows
green constantly
for amp value
set
Charging process interrupted,
will restart again later by itself.
If no error message is displayed, the
charging has been ended or paused by
the vehicle by means of a normal
command. This situation has been
observed in the Renault Zoe in particular
which stops the charging process when
the battery gets hot among other reasons.
All LEDs off
Fuse blown or FI (RCD) in the
building’s distribution network.
The vehicle has previously
charged at a higher amperage
than that displayed on the
JUICE BOOSTER 2.
It has been observed that the Renault Zoe
ignores the default current value and sets
its own value.
Charging does
not start
The Renault Zoe has difficulty charging
lower than 13A with a 3-phase line and
lower than 8 A with a single phase line.
The fault is in the design of the car’s
charging unit.
AC RCD and/or
DC RCD
repeatedly
triggered
The vehicle is sending residual
currents into the mains network
or is producing a short circuit.
Sometimes, for various reasons, the
Renault Zoe produces serious errors. The
power supply quality can, but does not
necessarily, act as a trigger (e.g. sudden
unbalanced mains load or loss of a
phase).
The error is always generated by the
vehicle however, always goes away
spontaneously and is in no way related to
the JUICE BOOSTER 2 which complies
strictly with the standard and therefore has
to interrupt the charging process for your
safety.
