An EV is as convenient as a mobile phone. Come home, park, connect the charging cable and forget all about it until next morning, when it is all set and ready to go.
If you live in an apartment building, you run the risk of having too many chargers, leaving your EV without juice. But if you live in a private residence and either use a regular electrical socket to charge or your EV has very low charging capacity, one night may not be enough to give your EV a full charge. To keep early morning disappointments at bay, it would do you good to know about the various levels of home charging.
Almost all car makes have a level 1 charger in their standard equipment. That charger is meant for slow overnight charging. One end of the cable has a Type2 plug, which you plug into the car. The other end has a regular three-pronged 220 V plug, which can go into every household socket.
That type of charging does not need any additional electrical devices, but we only recommend using it temporarily or in an emergency. Make sure the socket and wiring are in good working order. Know that using an extension cord may cause a voltage drop, which may hinder or stop the EV from charging. Whenever necessary, talk to your power grid operator before charging.
Level 2 charging is much safer and more effective compared to a regular electrical socket.
These chargers are not connected to the internet. They work well for people who want to charge their EV without all the bells and whistles.
If you use a meter, you can monitor your power consumption, but you cannot use automatic optimisation based on electricity prices.
This type of charging can be suited to private residences that to not need shared power supply management.
Sunday in an apartment block. What happens when everyone wants to charge their EV, do their laundry and cook a roast at the same time?
In an apartment building, these chargers use mobile telephony to connect with other chargers in the building and make up a single manageable charging network.
There are two main types of stations with an internet connection:
In a non-controllable station with internet connection, the load can be managed by calculating the maximum capacity in the power supply and distributing the available electricity between all the connected chargers. If 120 A is the maximum available capacity in the system and three EVs are connected, each of them gets 40 A.
A controllable station with an internet connection is a smart charger and can manage the load in the power supply. It can monitor other demand in the building to make sure the overall demand does not exceed peak demand. That makes the best use of the power system to charge EVs faster and optimise costs based on the electricity price.
The VOOL charger is the first charger to give access to all the power in the grid. No limits, no surprises. No charging failures or half-full EVs in the morning.
Hairdryer, washing machine and oven all turned on at once? Slower charging.
Everyone is asleep? Maximum power, faster charging.
The VOOL charger automatically monitors electricity exchange prices. We will know when the prices are lowest and charge your EV accordingly. If you do not care about the price, you can charge your EV whenever.
When it comes to an apartment building, you have to make sure everyone is happy. The control system, which is especially well suited for shared VOOL parking lots, distributes the available power between the connected EVs and does so fairly and evenly every time. VOOL can help you avoid or postpone reinforcing the power grid that supplies the building and the related costs. Invoices are created automatically based on the power consumption of each EV owner.
VOOL is the first complete EV charging solution making reliable, smart, and cost-efficient charging available for everyone. Affordable and hassle-free EV charging fastens the energy transition. VOOL means hardware and software made inhouse, flexible charging options for private users and businesses. You can save money with smart charging and earn money opening your chargers to other EV owners.
