Whether we like to admit it or not, charging batteries has become part of our everyday existence, just like the morning coffee or brushing your teeth at night. Take mobile phones, for example. We plug them in every night, and chances are they haven't been completely depleted in a long time. The same goes for laptops, razors, and power drills. We blindly trust that there is sufficient power left in them. And very soon, we will do the same with regard to electro-mobility.
After all, an electric car gets a full charge overnight through a conventional outlet. And no one will be driving it till the battery is dead anyway. Instead the battery gets charged when it is convenient along the way. Just as we do with our mobile phones.
Using permanently installed charging stations, the charging time at home can be shortened dramatically. These so-called "wall boxes" are connected to high-power current outlets, just like your electric stove, and can charge your car's battery with up to 11 kilowatts of electricity, making them five times more powerful, and quicker, than a normal outlet capable of delivering only two kilowatts on a continuous basis. The new e-Golf, for example, with its impressive battery capacity of 35.8 kWh, can be completely charged within five hours using a wall box. That is, if the battery is completely depleted at the outset. Once charged, the car is ready for up to 300 kilometers of emission-free driving.
