Vivarail also has a battery version entering test.

Greater Anglia's battery-EMU project has disappeared without trace.

It was a trial that tested what it was supposed to. It found that the
technology works, but battery costs need to come down more to get a
reasonable range on the batteries. It's really no different to
electric road vehicles: if you want a decent range and performance,
they cost a lot (see Tesla vs Leaf).

Perhaps the battery D-train (or is that E-train?) will keep costs down
by having smaller battery packs, which may be adequate for its lower
speed and shorter range?

It will be interesting to see. All current battery trials are based on
partial mains operation.

Yes, I don't know how, and how often, they plan to recharge these
batteries.
