The document discusses the impact of air pollution in the UK, highlighting its contribution to significant health issues and emphasizing the need for a transition to electric vehicles (EVs) to reduce CO2 emissions. It reviews the current state of EV technology, the growth of EV registrations, and the challenges and opportunities presented by the shift towards electromobility. Additionally, it outlines the necessity of improved charging infrastructure and maintenance considerations for effective EV integration.

Air quality in the UK
The issue today
Today:
• NO2 and particulates have replaced SO2 and soot as the main
pollutants
• Air pollution is responsible for 40,000 premature deaths in the UK
• Over 3,400 hospital admissions for air-pollution related health
issues per year in London alone
• Children are the most affected
• UK health costs estimated at £20 billion per year
• Road transport is the most significant source of NO2, particularly
diesel-engine vehicles
• 80% street-level noise pollution from vehicles.

The Case For EV
Since 1990, The UK’s CO2 emissions have consistently
trended down in every area except transport
If we de-carbonise transport by switching to EV this has
an immediate and significant effect on our CO2 output –
even if the chargers are powered from the ‘cleaner’ fossil
fuels, due to the efficiency gain of bulk power generation
>50% of the UK’s power now comes from
‘renewable’ sources
Total Cost Of Ownership of EV already
lower than a typical fuel equivalent
Capital Cost of EV will drop below ICE
cars around 2030
About 20,000 public
charge connectors, and
growing
Regular maintenance is
essential!

Dieselgate
Volkswagen have been fined for developing and installing emissions-cheating
software on 10.7 million vehicles:
• $ 4.3 billion in US
• € 1 billion in Germany
• Class action lawsuit in UK
• Further civil claims pending in Europe
Diesel emissions-cheating not confined to VW:
• Daimler ordered to recall 238,000 vehicles
• Audi ordered to recall 224,000 vehicles
• Mercedes recalling 3 million vehicles for software ‘update’ ahead of prosecution
• Fiat Chrysler under investigation by EPA in US and DfT in UK for possible emissions cheating.

Electromobility Solutions
A long history of innovation – interrupted by gasoline.
1834:
Thomas Davenport invents the first electric car
Electric cars hold all land-speed records until 1900
1903:
World’s first speeding ticket issued – to the driver of an electric car
1908:
Henry Ford buys his wife, Clara, an electric car
Over 38,000 electric cars on the roads
But despite Internal Combustion Engines taking over – electric vehicles never quite went away.......

The four types of electric vehicle available now
Conventional fuel with
electric motor top-up
Battery range less than
30 miles. Electric
operation is mainly to
reduce CO2 emissions
Uses energy stored as
liquid hydrogen
Chemical fuel cell converts
hydrogen to electricity
without burning. Only
emission is water, and
these vehicles have a
range typically of 300 miles
or more
Toyota Mirai
Mitsubishi Outlander
Nissan Leaf
Wholly electric vehicles
powered by batteries
Currently most manufacturers
offer pure electric cars with a
range of 100 miles or more
Battery Electric Vehicles (BEVs)Battery Electric Vehicles (BEVs) Plug-in Hybrid Electric Vehicles (PHEVs)Plug-in Hybrid Electric Vehicles (PHEVs)
Fuel Cell Electric Vehicles (FCEVs)Fuel Cell Electric Vehicles (FCEVs)
Similar to BEVs but include a small
petrol generator on board
Range is extended by the generator
charging the batteries on-the-go if
needed

But are they GREEN ?
•Large-scale power generation is 65% efficient
•ICE engines are 20% efficient
•BEV is ~35g/km CO2 (charged from gas-fired power)
•An ICE is ~120g/km CO2 – 4 times worse
• plus NOx, SO2, N2, CO, particulates.....
•EVs reduce road noise and pollution in our cities

AC or DC charging? – the basics
AC
•Batteries are charged by an AC/DC converter permanently integrated into the vehicle
•Converters need to be small/low-cost/light/reliable/cool
•Maximum charging rate is determined and controlled the charger and is the SMALLER of:
•Charger
•Cable from charger to car (auto-sensed by charger)
•Converter in vehicle
•Typical converters are 3.4kW or 7kW (1 phase) e.g. Nissan Leaf (3.4kW or 7kW) and BMW i3 (7kW) – slow!
•There are VERY FEW cars with larger AC/DC converters!
DC
• When connected to DC, batteries are charged directly by the
charger, by-passing AC/DC converter
• Charging rate is determined by the battery – 50kw now, 350kW
soon – much faster than AC charging.
• Two incompatible standards with different plugs...
• CHAdeMO (Japanese)
• CCS/COMBO2 (European)
1kWh = 3.3 miles range!
