Sounds to me like the following needs to be done.

A.) Additional Buses are required to cover PVR as there is not enough.
B.) Re-charging points are required across the route to boost battery during the day.
C.) Re-work of "Service Scheduling" i.e. interworking of CLS Shorts/Durham Longs and finding alternative solutions to combat issues being faced currently thus to ensure EV's are out in service for the full day from first service to last service.

Can't foresee the above being an issue with the 58's given the operational milage will be significantly less than the 21's. 

One thing I would potentially look at is cutting the Brandon runs to terminate at Durham and then have alternative service cover the Durham-Brandon section which would save 7 miles of battery milage, iirc from the current scheduling they do 3 Newcastle - Brandon returns per day which would save 21 miles per bus used which in turn would see the efficiency percentage increase as the Buses would have more battery to enable them to stay in service longer per day.
