Your own charging station: safely charging your car at home
You want to charge your electric car or plug-in hybrid without spending hours searching for charging stations? Then you need your own charging station at home.
According to Statista, there are only about 8,700 public charging stations for electric cars in Germany (as of 14 March 2018). Too little to ensure mobility. Ideally, charge your electric car in your garage or anywhere else on your property. But how? Simply by plugging in?
Refueling at the house socket
Yes, in fact, a conventional household socket with 230 volts is the simplest variant. All you need is a control box: the In-Cable Control Box, ICCB for short. What for? In the power grid flows AC. But to charge your battery you need DC power: The energy flows in one direction only.
The disadvantages of the simple power outlet: Long charging times and high network load. It can take a full day until the electric tank is full, because it is loaded with low efficiency at about 2.3 kW of power. In addition, the power grid and cable are heavily used. It increases the risk of cable fire.
Power is faster
Faster and safer you charge your battery with high-voltage. Most households already have power connections, such as stove or washing machine. With 400 Volt voltage, the charging time is significantly reduced. However, you will need an ICCB controller even with heavy current.
The most convenient way to charge the electric car at home is to use a wallbox. It also operates at 400 volts and charges around 22 kW at up to 32 amperes. Since the charging controller is already integrated, you do not need an ICCB box. Wallboxes, however, cost between up to 1,500 euros. But some electric car manufacturers offer them at a discounted price or for car purchases or leasing.
Easy charging with the wallbox
Speaking of costs: Some electricity providers are cheaper at certain times of the day, keyword: Night electricity tariffs. Since most car owners charge their batteries anyway at night, a power tariff comparison could be worthwhile.
Also important is the type of plug. Most wallboxes and public charging stations work with the so-called charging plug type 2, the Mennekes plug. European automakers prefer him. Unlike the Asian: They usually equip their cars with the charging plug type 1 for 240 volts with a maximum of 7.4 kW. In the local market, they offer their charging cables with a "Euro plug" on the other end of the cable.
Tips for electric car drivers
Nothing works without an electrician: only he can assess the loads that your connections can endure and the installations and lose weight. And what if your car journey exceeds the battery range? Websites or apps like plugsurfing or e-gas station finder show you the way to the nearest public charging station.
