PARIS – I love you
You may ask what PARIS in France has to do with EV charging? Not much but for the name. WHAT?
The infrastructure bill (NEVI program) provides $5 billion until June 2027 to help states create a network of 500K public charging stations (EVSEs). By 2030 we will need 1.2M EVSEs.
Sounds good BUT:
According to a recent study by UC Berkeley over 27% of all
EV charging stations in the San Francisco Bar area are
non-functioning, and slows public adaptation of EVs in California.
“EV owners are fed up with broken EV chargers
and janky software”. JD Power surveyed 11,554 electric vehicle and plug-in hybrid vehicle owners from January through June 2022. Despite big growth in the number of public EV chargers in the US, EV owners say the overall experience still sucks.
So, we better get it right before we install 1.2M public chargers and ensure that they are reliable, functional, future proof and provide a good charging experience for EV owners.
The good news – this is not “rocket science” – Tesla has already shown it can be done.
The current situation is like the mobile phone industry in 2007+.
– One company – Apple – got it right from the start and introduced the OS – a close cousin to the well-proven macOS for desktop computers. This provided a superior experience for smartphone users.
– For the rest of the smartphone gang (Nokia, LG, Motorola, Siemens) it was like the Tower of Babel confusion. Each had its own software (OS).
– Then along came Android from Google and the rest is history. We need a similar “Android” software for the charging stations.
So, for all the EVSE OEMs (except Tesla) we should introduce a “PARIS” accord😊:
Plug & Charge should be automatic when the EV is plugged into
the EVSE and allow EVs with different subscription plans to charge and be billed automatically. No fumbling with credit cards or RFID.
Manual authentication not be required. Plug in
initiates automatic authentication in the background.
Charging ports should have an average annual
uptime > 97%. The EVSE software should have higher granular access to the hardware and provide for high reliability and availability through predictive fault analysis, fault detection and remedy.
Every ICE car can tank at every gas station. International standards like e.g. ISO 15118-20 (EV-EVSE) and OCPP 2.0.1 (EVSE backend) should be required to ensure that every EV can charge at every charging station.
The EVs when connected will become a large part of the electric grid and may become a national security threat that could take the grid down. High-level of security must be built-in from the start using international standards like ISO 15118-20.
Look out for the company Switch in UK with their software suite Josef – “Joint Operating System for EV chargers” which integrates ISO 15118-20 and OCPP 2.0.1 seamlessly. The new “Android” for EVSEs?
