Sorry for the delay, I have only just seen your replies.
In November last year I wrote to BPC management pointing out that the product was being sold as a 'smart charger' and, despite two replacements and numerous communications with the Support team over 6 months, the charger was still not fit for purpose. Within a week I received a phone call from the one person who has some technical understanding of the product and how the car/charger interface works. He visited and spent over 2 hours testing and measuring the Control and Pilot signals between the car and charger, which proved that the car was behaving correctly and the charger had adequate communication (3G signal) but the charger was 'locking up'.
According to BPC they have done nothing to make it work and are still awaiting feedback from their development teams!
In order to get a copy of the internal report produced by their Engineer, I promised not to share his details or the report itself. In theory, he now sees all escalated calls through the Support team but, if you wish, I will forward your Call and/or Unit number to him, to make sure that your calls are escalated and that you are in the 'melting pot' for any updates.
I am still running tests and proving feedback to BPC but, with one exception where the vehicle was plugged in 12 hours before the schedule start time, it has been working perfectly since 10 March.
I hope this is some help
