10. Charging Modes

zappi has three different charging modes and a "STOP" mode which can be selected simply by pressing the
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 the explanation of each charging mode.
FAST
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.
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 below 1.4kW.
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.
The output from zappi is turned off
In STOP mode zappi will not charge your EV. This includes the boost modes and timed boost. zappi will
continue to measure power and communicate with the other myenergi devices.
