Wait, you put 600kWh of batteries on a sprinter van?!? I wanna know more...that's insane (base eSprinter is like ~115 kWh, right?)
Also the larger battery means the individual cells can be pulse charged much slower and each cell individually at the rate where it doesn't damage that much. I measure the temperature, voltage and current of each cell so they never overheat. This is how I get many more cycles out of each cell so they last 50 years. It is also safer, with thousands of temperature measurements several times per second not a single sell gets warm, and if they ever do it is because it is damaged and we can immediately disconnect it and tell the driver where to locate it and remove it.
For a truck these thousands of battery cells discharging slowly in parallel becomes the reason all trucking companies will be forced to switch from diesel to electric, it is several times cheaper per mile or km. Lower energy cost, lower maintainace, lower downtime, longer life. The only thing you would want is that the maximum weight limit per truck goes up so you can ship more per trip. Right now you ship little kilo's if you carry a heavy battery. But charging with your own solar at home base is so much cheaper that it is worth to do two trips versus 1 trip with diesel.
The reason electric trucks are not yet everywhere is that the truck makers ask ridiculous amounts for battery cells that are still wired in series and discharged too fast to last long. Simply bad design. We need a disruptive electric truck startup and we need a disruptive battery startup. Investors welcome...
No, my eSprinter camper is a small room with kitchen, bed and shower. The trailer ways 3500 kg, the eSprinter 2670. I could haul at least 889 kilo more. If I had the bigger motor I could haul twice as much.
