18. Preconditioning

Most EV's provide a preconditioning function that can be used to prepare the vehicle for a journey – typically
by warming/cooling the inside of the car, defrosting the windscreen and possibly warming the battery so that
it is in the optimum state for driving the vehicle.
To avoid draining the battery to precondition the car, the
power needed is provided from the electricity supply.
Note: This feature only works if
the EV because the battery was full.
If this is not the case, then the only way to ensure that the battery is not drained during the EV preconditioning is
to set a Scheduled Boost to coincide with time when the EV will be preconditioning.

18.1 Setting Preconditioning

The preconditioning mode can set to "On" or "Off":

normal charging, in whatever mode it is set to.
Note: Some vehicles (for example the Tesla Model S) need a lot of power to warm a cold battery even for standard
charging. If you try to charge one of these vehicles in ECO and ECO+ mode the EV may charge for a short period,
stop because it does not have enough power to warm the battery and then immediately try to charge the EV again.
We cannot guarantee that the Preconditioning Mode will cope with this situation but provided the EV draws a small
amount of power the first time it tries to charge this should trigger the Preconditioning Mode, providing enough
boost power to warm the EV's battery and allow normal ECO/ECO+ charging to proceed.
