Quasi-monovalent concepts run primarily on natural gas, but also have a petrol tank as a mobility reserve with a maximum of 15 litres capacity. Exclusively at outside temperatures lower than minus 10 degrees and immediately after filling with CNG, a petrol-based start is necessary. After a short time, the vehicle switches to running on gas, once the conditions for smooth natural gas operation are met.
CCS charging (Combined Charging System) is the standard for quick charging in Europe. The CCS charging stations specifically designed for this combine AC and DC charging with a high charging capacity in a single system. With DC charging, the alternating current is converted into AC power outside the vehicle, for instance in the charging station. The benefit of this is that a higher output is possible and the charging processes are automatically shortened by this.
