Teething Issues We’ve had our V2H charger a while now, but had a couple of teething problems around a software issue that have made it somewhat hard to figure out the best way to use it. We are one of the limited number of customers who have been given an export limit by the DNO (Distribution Network Operator) telling us how much electricity we are allowed to export to the grid at any time.

Octopus Tariff Comparisons Changing Tariff At some point in November, we were experiencing consistently higher prices on Octopus Agile, and I decided to switch tariffs for the rest of the winter at least. Octopus have an “Intelligent Octopus” tariff that charges 7.5p kWh between 11:30pm and 6:00am each day, and around 30p kWh the rest of the time. This tariff is not supported by our V2H charger yet - they specifically say it’s not supported.

Today a nice engineer from ChargedEV called Steve fitted us a V2H charger. This is part of the world’s largest trial of Vehicle-to-Home bidirectional chargers being performed by Indra in the UK. What’s a V2H Charger? A conventional EV charger is one way - it takes the electrons from the grid and puts them into your car. A bidirectional charger on the other hand, not only lets you push electrons into your car, but also to pull them out again.
