I'm guessing, but I think this situation is associated with the combined 
charging system (CCS) connector:



Basically, it is possible for a charging station to support either ordinary 
Level 2 (AC) charging or Level 3 (DC) charging with a single charge cable and 
paddle.  I don't know if there are EVSEs that support both, or if only EVSEs 
that support one or the other are available even though the same connector 
would appear on both types.

Assuming that a CCS EVSE supports both Level 2 (AC) and Level 3 (DC) charging, 
then any vehicle (not just PIH) that is only capable of Level 2 (AC) charging 
might be seen as interfering with another vehicle's ability to use the EVSE's 
Level 3 (DC) capability since the (single) charge cord is then unavailable. 

While I tend to agree that an EV needs access to an EVSE with greater priority 
than a PIH (or so-called 'extended-range EV' ;^), since the EV cannot move 
without charge while the PIH can, trying to restrict access based on vehicle 
type or charger capability seems like a slippery slope to start down.  Do I get 
to unplug your 3kW-charger Leaf and plug my car in because my 6kW charger is 
able to utilize more of the EVSE's capability?  Can I unplug your PIH to plug 
in my EV, because I *need* a charge to get home while you want one "just" to 
avoid running the ICE?  What if I unplug your Tesla because you've got tons of 
battery capacity while my Leaf's much smaller capacity battery means I rely on 
being able to add a bit of charge before heading home? ;^>

Cheers,

Roger.

Ban plug-in hybrids from EV charging bays, say experts

I was hoping some one would comment on this.  Can someone make sense of 
it for me?


They imply that 3kw level 2 charging interferes with 50kw level 3 
charging.  Of course, barring terrible parking space configurations, 
that is not possible in the USA.  Is it possible in UK?  Or Europe?

Report argues plug-in hybrids take too long to recharge and block
all-electric cars with rapid charging capabilities from using bays

Plug-in hybrid vehicles (PHEVs) should be banned from using electric vehicle
(EV) charging bays, freeing them up for use by ‘pure’ EVs, according to a
new report.

Most PHEVs on sale today are limited in the charge rate they can accept to
around 3.7kW, yet the fastest rapid chargers deliver at least 50kW, a rate
accepted by most pure EVs. That means it generally takes around five minutes
for an EV to receive 15 miles worth of charge, while a PHEV would take an
hour to receive the same range.

EV charging infrastructure expert Harold Dermott argues that – until PHEVs
“have both a greater electric-only range and can accept electricity at
faster rate” – they should be banned from using charging bays at motorway
services areas ...

Writing in a report for the RAC Foundation entitled Development of the UK
Public Chargepoint Network, Dermott expresses concern that if PHEVs continue
to block EVs from using rapid charging bays, the charge points will “never
be available for their essential purpose of charging BEVs [battery electric
vehicles]” and the income of network operators will “collapse”.

The study also notes there has been an improvement in the reliability of
public charge points – with a reduction in out of service units from 14.8
per cent to 8.3 per cent – but says this is still too high a proportion. 

In addition, two types of recharging behaviour are identified in Dermott’s
report – journey charging, where the primary purpose of being at the charge
point is to “fill up with electricity” – and destination charging, where
recharging is secondary to other activities, such as shopping, visiting a
leisure centre or parking at a railway station.

]

The report calls for charge point locations – especially larger hubs – to
offer the same services and facilities one would expect at a typical fuel
station, such as protection from the weather, food and drink, toilets and
lighting.

RAC Foundation director Steve Gooding warned that if cars can only be
recharged at a limited rate, then installing “ever-faster and more powerful”
charge points will “waste money”, adding that it’s “key” for cars and
chargers to be compatible.

Gooding emphasised the “fundamental” need for all parties involved in the
industry to communicate with each other, as “policy, technology and the
market are almost falling over themselves”.
