Charging questions
How often should I charge my car?
Often it is only one or two hours the electricity is cheap every 24 hours. Even if our charger is a 22kW charger, most cars are charging with much less power. For this reason we suggest to charger every night.
Should I charge my car fully?
Most experts say you should not charge more than 80% of the battery capasity to ensure that the battery last as long as possible. We recommend to set a limit of 80% charging in the app for the car.
How do I charge an almost empty car?
If you don’t need a fully charged car fast you can just leave the app in «Smart Charging» modus. Then the car will be charged while the electricity is cheap. In case you need the car fully charged fast you can set the app to «Charge full now».
How long time will it take to charge an almost empty car?
This depends on the size of the battery in the car as well as how fast the car is able to charge. As an example, you may need about 6 hours to charge a car with a 60kWh battery up to 80%.
How does ZmartCharge calculate the next charging session?
ZmartCharge stores all earlier charging sessions and based on this we know how much your car will charge per hour and how much your car charge per day in average. We then use these data when we select the cheapest hours for the next charging session. Every day we update the spot price for every hour for all area in Scandinavia.
How does ZmartCharge know what price area I belong to?
When you add a new charger in the app we will find the price area based on the geolocation for the charger.
How to use the ZmartCharge App
Why do I have My Places in the app?
In our app you can have many places. By example you can have your home in a city and you can have your cabin in the mountain Then you can have one or several chargers on each of these places. By example, in case you have limited electricity in your cabin and have several chargers you can add our load balancer module to balance the electricity consumption between the chargers and the cabin.
How to lock my charger for un-authorized people?
Go to the «Charger Settings» from the Main Page. On the «Restrict Charger Access» pull down, select «By Phone» Please note that for this to work you will need to allow the app to always access Bluetooth, Mobile Data and Locations in the Settings section of your phone.

In case your charger is hanging freely available outside your house we also suggest that you buy a ring screw and a lock. Screw the ring screw in the wall and thread the lock in the ring of the screw and fasten the cable in the lock.
How do I add others to use my locked charger?

Then you press the plus sign on the “Guest Access Administration”. Here you will enter a nick name for the guest and his phone number. If it’s a family member you can click on Forever and Save. Then the person you want to give access to can download the app and register and he will get access to your charger right away.

In case you by example have a cottage you want to rent out, you can add your renter to the guest list and set a start and end date and time for when the renter shall be able to use the charger. In case you charge separately for the charging, you can check in historical data in your app for how much electricity the renter has used. The renter will also be able to see this in his app.
Are the electricity prices in the app accurate?
In case you have correct country and price area on «My Places» ZmartCharge will collect correct electricity prices for every hour for your price area.

In case you have a fixed price agreement, and has entered the correct amount per kWh, the system will also calculate the price correct accordingly.
Problems
The App is saying the charger is not connected to Internet
This can be caused by the charger not having electricity or the charger has lost the connection with Internet.
In case there are no lights on the charger please check that the charger plug is plugged in and that the fuse for the charger is set to on. If this is the case, we can send you a new replacement charger.
If the lights are lighting on the charger, please check by using your phone that WiFi is available where your charger is. If WiFi is available, you can go to «Charger Settings» , «Charger Network Connection» and verify that the WiFi Settings is correct. Press save and you can follow the connection process in the app. If the process says successful, please go back to your main screen and see if the status indicator over the charger has changed to green.

What Charger shall I choose?
Red 3 Phase plug for all car brands and models
TN Net is standard in many countries apart from Norway. Please check your main fuse box if you have a red sticker saying 400V. If this is the case, you shall choose Red 3 Phase Charger. In case the sticker is a blue or black, please see the blue options. We also suggest to consult this with the electrician that will install your contact for the charger.
Blue 3 Phase plug for Tesla
Please check your main fuse box to see if it’s a blue or black sticker saying 220V. In case you have a Tesla, you can choose Blue 3 Phase. For all other brands we suggest choosing the blue 1 Phase. In case you have both a Tesla and another car of another brand we also suggest the Blue 1 Phase plug. We also suggest to consult this with the electrician that will install your contact for the charger.
Blue 1 Phase plug for all other car brands and models
Please check your main fuse box to see if it’s a blue or black sticker saying 220V. In case there is, you shall choose Blue 1 Phase in case you do not have a Tesla, you can choose Blue 1 Phase. We also suggest to consult this with the electrician that will install your contact for the charger.
Why can’t I use 3 Phase Blue on my 3 Phase car
In Norway we have 2 different electric networks, i.e., IT Net and TN Net. The IT net use blue plugs and the TN net use red plugs. Norway is one of the few countries that has IT Net. Most cars that support 3 Phase charging is made for TN Net (Red) only. The only exemption is Tesla that supports both IT and TN 3 Phase charging. Most cars made for 3 Phase TN Net will simply refuse to charge if they are connected to a Blue IT 3 phase plug. Some brands even say this is dangerous, and may cause a problem with the car, and they will not cover this on warranty. This is the reason you should only connect a car supporting 3 Phases to a Blue 1 Phase charger, unless you have a Tesla.
Is this 3 different chargers?
No, the chargers are the same. It is only the plug that is wired differently. In case you bring a charger with a blue plug to a home with red socket the electrician can simply change the plug.
