Charging Modes
zappi
has three different charging modes and a “STOP” mode which can be selected simply by pressing the
and
buttons when the main screen is showing. The charge mode can be changed before or during a charge.
Regardless of the charge mode, all the surplus electricity is used.
zappi
's special eco charge modes limit the amount
of grid electric used. Below is explanation of each of the charging modes.
Charges at the fastest rate
.
Fast Mode will charge the EV at the fastest rate and will import grid electricity if there is insufficient surplus
generated power.
The actual charge rate is dependent on the EV's onboard charger and the grid supply voltage. Some vehicles can
charge at 11kW or 22kW on a 3-Phase
zappi
, but many EV's have lower charge rates. The maximum charge rate for
the single phase
zappi
is 7kW.
Adjusts the charge rate to limit the use of electricity
.
The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in
the home, thereby minimising the use of grid power.
Charging will continue until the vehicle is fully charged, using available surplus power.
If at any time, the available surplus power falls below 1.4kW, the shortfall will be drawn from the grid.
Note
: The EV charging standard does not support charging below 1.4kW.
Adjusts the charge rate to limit the use of grid electricity and will pause the charge if there is too
much or any grid electricity being used
(setup dependent)
The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in
the home, thereby minimising the use of grid power. Charging will pause if there is too much imported power,
continuing only when there is enough surplus power available. The surplus power threshold at which the charge will
start or stop can be set using
Min Green Level
in the
ECO+ Settings
of the
Charge Settings
menu.
The actual green contribution percentage is shown when the charge is complete or when the
zappi
has been
disconnected from the EV.
It is possible to charge the EV using only surplus renewable power, if there is sufficient surplus power available and
a boost option has
not
been set.
(
Please note:
The EV charging standard does not support charging below 1.4kW)
Example: when
zappi
is set to a Min Green Level of 100% you will need in excess of around 1.4kW of surplus energy
available to start the charge. If the surplus falls below the 1.4kW threshold the charge will pause until the threshold
is once again met. After a short delay
zappi
will resume charge.
If preferable, you can set the
zappi
to share power from the grid and a generation source to ensure a charge is
always maintained. For example, the Min Green Level could be set to 75%. A charge will then start when there is a
surplus of 1.05kW, taking a further 0.35kW from the grid. It is worth noting that this is only required to start a
charge. If a higher amount of surplus becomes available it will be consumed, resulting in less being drawn from the
grid.
