With battery size (pack = 144v) and cell type chosen the charger can be selected, a common model is the Zivan NG 3, specifications look very good – it is selectable modes for different battery types so if technology changes I can adapt with it. The only problem is the voltage is fixed so increasing is not an option.
I’m interesting in being able to take 220v and 110v principally as I have 220 socket conveniently installed in my garage so could charge faster.
Definitely have to follow the pattern of other builders in replacing the petrol filler with a plug, that is nice up front job that can be taken care of ahead of other steps.
The Manzanita Micro ~PFC-30 is multi voltage input and has a buck enhancement option, so very quick charging indeed. This charger is actually a simple CI/CV type, but very well made.

Bus charger inlet is a ~L6-30P
Since there is a range of connections found at friends homes and workshops I decided to build a cord set with multiple options
