I really don’t understand this one and why it’s a good idea.
The bus has its battery drained back to the grid to provide power, but then its self-same battery recharged from the grid before it can go out? How is this a benefit?

I really don’t understand this one and why it’s a good idea. The bus has its battery drained back to the grid to provide power, but then its self-same battery recharged from the grid before it can go out? How is this a benefit? As mentioned in the article, the point is that the vehicles provide energy to the grid when demand is high, and then take energy from the grid at times when demand is low. So it's a way of balancing the load on the grid more efficiently.
It's probably a bit misleading to suggest that the buses will be "generating" electricity, given that the energy will all ultimately come from the grid. But one of the main problems with electricity is that it can't be stored cheaply, so balancing supply and demand is a big issue. It might seem counter-intuitive but what this trial is doing is using buses as storage to try to balance this out. It'll be interesting to see if it works in practice.
