Warnings:
	40 % of all chargings you made in high tariff!This means that you will pay more as would charge in low tariff (during the night)! Please open planning tab to configure scheduled planning or contact your energy supplier which will provide you more informations about managed charging, which is even more effective. Charging in low tariff is also more ecological, as grid does not need to include additional power facilities po provide your energy.

	Charging station noticed that you are not charging your vehicle every day! Charging your vehicle over the night has several important benefits. Number of battery recharging cycles dramaticaly imporoves if your battery is 80% (40000 chargings) filled when you start charging, instead of charging almost empty battery( 20% - 2000 chargings). If you charge more filled battery over the night you can charge with smaller power, so you do not have to increase you household feeder power to be able to charge you EV. Charging in low tariff is also more ecological, as grid does not need to include additional power facilities po provide your energy.

How station power management is working:
In fast charging mode vehicle will be charged with maximum available power. Maximum power is limited with your: on-board car charger power, "cable power capability" and with your "maximum charging power setting", which can be set in Settings tab. When fast charging will be started, vehicle will be charged with lowest of this power values.
Example:If on-board charger allows charging with 20A and cable allows charging with 16A, and your maximum charging power setting is 4,6kW (20A), vehicle will be charged with lower value - 16A.
If your maximum charging power setting is 4,6kW (20A), and cable allows charging with 32A, vehicle will be charged with lower value - 20A.
Current value of "maximum charging power setting" is

16
A.

If Planned charging mode is selected on station user interface, station can run in two modes: Manualy scheduled charging or as Charging controlled by your service provider. You will select planned charging mode if you have enough time to charge your vehicle and want to save money or charge more ecologicaly. Even in Planned mode, charging power is still limited with maximum charging power, "cable power capability" and on-board charger.
In Manualy scheduled charging mode you are able to control charging plan by setting charging power for each hour in a day.
If Charging controlled by your service provider your service provider will remotely manage charging schedule. Contact your service provider to check what kind of benefits can you get. This function is enabled only if valid plan is received from your service provider.

All charging modes can operate with "Smart building power management" function, where maximum power is calculated dynamicaly due to the current status in buliding installation. Multiple stations can be connected into Smart building power management.

Manual charging schedule

Drag points for specific time intervals to set charging power for selected time interval. Charging power is represented in % of maximum charging power setting, which you set under the settings tab. Current value of "maximum charging power setting" is

6
A.

If possible, plan most of your charging in night time (low tarrif - GREEN AREAS), becouse is more ecological and cheaper. Low tariff time interval is from 22:00 PM to 6:00 AM (GREEN AREAS) between working days all during the weekend.

Miminum charging current is 6A (1,4kW). If user sets schedule lower than 1,4kW (RED AREA), then charging will be stopped in that intervals. It is allowed to stop and start charging only three times per charging.

You have totaly saved :: 384 tons of CO2 ( since 12.4.2011 - compared with gasoline car )
Petrol car emissions = 224 g/km	The energy lost (and associated emissions) extracting oil, refining it and transporting it to the petrol station is around 18 % in United Kingdom . Thus, the well-to-tank effciency is 82 %. The vehicle CO2 emissions figures quoted by the manufacturers are tank-to-wheel figures. Taking into account the well-totank effciency, and average petrol car emissions 184 g/km the total emissions are 184 / 0.82 = 224 g/km.
Average grid mix emissions = 164 g/km	Production of CO2 is 891 grams of CO2 per kWh produced in electricity generation.Approximately 9 % of the plant output is spent running auxiliary loads within the power plant itself, and the losses incurred transmitting and distributing the available electricity to the point of use are 6 % , so the total generator-toelectrical-outlet effciency is 0.91 x 0.94 = 86 %. The effciency for converting electricity from the electrical outlet into energy stored in the car battery is about 87 % ( a combination of an 8 % loss due to ineffciency in the AC-DC converter and a 5 % loss from intrinsic ineffciency in charging the battery ). The generator-to- electricaloutlet effciency is calculated above as 86 %. Thus, the energy that must be generated in the grid in order to charge the 22 kWh battery in your EV is 22 /( 0.87 x 0.86 ) = 30 kWh of electrical energy. The distance driven per generated kWh is thus 160 / 30 = 5.4 km per kWh. Thus, from the national average grid mix, the emissions per km are 891 / 5.4 = 164 g/km. This is 164 / 224 = 73 % of the emissions of a comparable petrol car. That is, 27 % less CO2 is emitted by the electric car.
Green electricity emissions = 0 g/km	Electric cars are significantly cheaper to run and operate per kilometre than petrol vehicles. For an increased cost compared to �black electricity� of around one cent per kilometre, an electric car battery can be charged using 100% green power. In this case, there are no associated emissions.
