If you want to charge quickly, it is best to drive with the battery as empty as possible a pillar.. And pulls the plug at a certain point - SoC 80.
How much energy is left in the battery is not just about the range of one E-cars important. It also plays a role in shops. Anyone who talks about how “full” a battery is, often uses the English expression “State of charge", Abbreviated to" SoC ".
The SoC is usually given in percent. 50 percent roughly corresponds to half of the full charge or the maximum usable capacity. E-car drivers often find the charge level in combination with the percentage value 80. The 80 percent filling has emerged as the usual target value for fast charging in everyday life and in the manufacturers' technical data. Above this limit, the further filling of the battery becomes slow and slow, so that you usually do without it.
In return, the lower the SoC, the faster an electric car charges. The navigation devices of many models are therefore set by the manufacturers in such a way that they only recommend a quick charge stop relatively at the end of the range. Because up to an SoC of 50 percent, many e-mobiles can call up their maximum charging power. After that, the speed drops rapidly.
