aforementioned mercedes MMA should curtail those toilet stops
...
Of course, this must be different for a production car that will debut in 2025. Short charging times are important for customers. That’s why Mercedes opted for an 800-volt system for the CLA – unlike the large EQS. There are more factors in favour of 800 volts than just the charging power: the lower amperage for the same power means the cables can be thinner and lighter.
The charging power that the CLA achieves would not be easily possible with a 400-volt system and today’s charging infrastructure: the data sheet lists 320 kW at the peak. “What is much more important to us than the peak power: how much range can I recharge in ten minutes,” explained Torsten Eder. “We can achieve 300 kilometres here!” His developers later added that the charging time from ten to 80 per cent is less than 22 minutes. With two charging stops of ten minutes each, 1,200 kilometres should be possible.
