how about if you arrive at a charger that doesn't work you can select charger broken as normal, but you get re routed to the next available working charger. and not the same one that is broken that happened to me.
Also the facility if you have a route planned to change what percentage you charge upto. Ie the planner will tell you to charge at say 30-40%?at stop one on an ionity and then tell you to charge again at a slower one. The option to add your own percentage Soc at each stop would be good so you could say decide to stop longer at a better site with more facilities and do a shorter charge at the one with less facilities/ slower charger.
