Chargemaster Keeps UK Charging Network 99% Operational

British electric vehicle drivers should feel lucky, as the largest charging network of roughly 10,000 points in the UK seems to be reliable.  Not so much for most of the regions in the rest of the world.

Chargemaster stated that over the last year, its owned and maintained infrastructure achieved a 98.7% serviceability record for all charge points on a month-by-month basis.

“Today, just two charge points installed and maintained by Chargemaster in London are not fully operational, and both of these are scheduled to be back online within the next few days.”

David Martell, Chargemaster CEO, commented:

“We are proud to have the best-maintained charge points not only in London, but across the entire UK electric vehicle charging estate. Our own Chargevision back-end management system is the best in the business and provides us with diagnostics on every single one of our charge points, every minute of the day.”

“We take maintenance and serviceability very seriously. As the UK’s largest provider of EV charging infrastructure, we have a responsibility to ensure that electric car drivers can rely on our network to enable them to complete their journeys.”

As there are plenty of AC charging points in this and other networks, the main question remains whether DC fast chargers are operational all or most of the time too?

On what planet is Chargemaster 99% operational. My experience, as am EV driver with 27,000 mile experience, is just because the map is green, don’t expect the charging station to be operational.

As for phone support; this tends to a mobile phone out of hours and “someone will look at it in the next couple of weeks” I have been directly told.

Not to mention the expensive cost of charging IN TOP of expensive car parking; my next car will NOT be a 100% EV due to this profit taking but a PHEV as using diesel is cheaper than paying Polar charging rates.

Also the inequality of paying for time charged vs actual kWh dispensed is totally unfair.

Don’t believe the hype.

Yep, I’ve given up on Polar/Chargemaster, ever since they introduced their new rates back in April. All the cost of a Diesel with none of the convenience! That said, rather than go for an ICE, I changed my EV from one with an 80 mile range to one with a 250 mile range and free DC fast charging included. Now I simply don’t have to bother with Chargemaster, I’ve got the range to get home and charge there.

I really don’t know whether I have the energy to try and look into the dubious figures of another EV charging company.

Please may we see the methodology that is in use to come up with near perfect reliability

And in the USA we have Blink… aptly named since you can always count on them being on-the-blink.

“98.7% serviceability” likely just means there is a network connection established. It does not give any indication to operational “reliability” to establishing a charging session; nor does it account for “accessibility”. eg: Are all Chargemaster station open to use 24/7 and have an active method to prevent being blocked by non-charging vehicles.

Reliability and Accessibility are the two most important criteria in measuring a networks usability. Without details on what “serviceability” entails it is meaningless and can not be compared to future, or to other networks.

There is a major difference between AC charging points (essentially electrical outlets) and DC charging stations (which use complex highvoltage power circuits).

It is very important to report AC (Level2) separately for DC Fast Chargers. Photos (above) only show AC Level2 charging points with no references to DC Fast Charging. When was the last time you experienced an electrical outlet fail? 99.99% serviceability is the expectation with AC plugs. (ie: 99.99% means offline for an hour per year, vs. 99% which means offline 4 days, or ~90 hours per year … 98.7% is 5 days, ~114hours per year)

From my 10k mile EVing experience, on the exceptional occasions when I have had the need to use a Level 2 CM EVSE, 50% of the time they have not been working.
