Just to remind us all, Electric Vehicle Supply Equipment, (EVSE) facilitates the charge for the operation of the electric vehicle, (BEV) or (PHEV).
Included in the (EVSE) you will find plugs, sockets, conductors and power outlets which allow communication between the charging equipment and the electric vehicle, (BEV) or (PHEV).
So, how quickly can you charge your electric vehicle, (BEV) or (PHEV)?
The length of time it takes for an electric vehicle’s battery to recharge is very much determined by how many kilowatts (kW) the charging point can provide and how many kilowatts (kW) the electric vehicle receive.
The higher the power, (wattage) the faster the charge.
As we already know there are 3 different rates:
Question, do different electric vehicles have different connectors?
The answer is yes, not all electric vehicles have the same types of charging connector
The electric vehicle is supplied with at least one charging cable
Rapid chargers and high power chargers
What is (EVSE)?
Electric Vehicle Supply Equipment, (EVSE) facilitates the charge for the operation of the electric vehicle, (BEV) or (PHEV).
Included in the (EVSE) you will find plugs, sockets, conductors and power outlets which allow communication between the charging equipment and the (BEV) or (PHEV).
What is an (EV) charge point?
A (BEV) or (PHEV) charge point is a single upstand ground or wall mounted structure that provides electrical energy, (power) to the vehicle through one or more electric socket outlets or tethered plugs .
What is (EV) charging station?
A physical location with at least one charge point installed to charge at least two (BEVs) or (PHEVs).
How does an (EV) charging station operate?
Once connected the (BEVs) or (PHEV) vehicle dictates how the electrical energy, (power) is drawn from the charge point, (grid). It therefore controls the speed of recharge and not the EVSE equipment.
Electrical energy stored in on-board (BEV) or (PHEV) batteries is recharged by connecting the (BEV) or (PHEV) vehicle to an external electricity supply, the electric vehicle charge point.
The (BEV) or (PHEV) vehicle converts the ac power from the electricity grid into dc power which is used to drive the electric motor using a converter.
A charging cable supplied in the (BEV) or (PHEV) is matched to the (BEV) or (PHEV) on-board converter. Once connected the speed of charging the battery is determined by the on-board charging equipment.
Note, different names are used to identify and describe the different charging speeds available for the (BEV) or (PHEV). These names indicate a range of power outlets and the charging times. Different Connectors are suited to each power outlet and speed.

What is a (HFC) Bus?
· A (HFC) electric bus is an electric bus that includes both a hydrogen fuel cell and batteries.
· The hydrogen fuel cell provides all of the energy for bus’s operation, whilst the batteries are there to provide peak power to the motors to meet rapid acceleration and steep gradients.
How does it work?
· The fuel cell power module onboard the bus generates electric energy through an electro-chemical reaction. The only by-products from the process are water and heat, there are no harmful emissions produced.
· Generated electric energy is used to provide electric traction and to keep the batteries charged.
· The by-product heat is utilised to provide passenger hearting comfort.
· Note, the batteries also provide storage for regenerated braking energy.
· All the energy required for the bus to operate is provided by hydrogen stored on board.
Where do you store the hydrogen on the bus?
How long does it take to refuel the bus with hydrogen?
· Typically you will be looking to around 5 to 7 minutes for fill of hydrogen.
Where do you source the hydrogen?
So, will the government experiment with hydrogen fuel cells for an entire town’s bus network?

As electric vehicle use increases the availability and access of (EV) charging will become an increasingly important factor for a broad range of electric vehicle users.
What is (EV) charging?
An (EV) charge point is a piece of street furniture that is used to supply electric energy for the recharging of electric vehicles, Battery (BEV), Plug in Hybrid (PHEV).
To facilitate charging, (EV) charge points come in a range of charge point types.
Standard charge points:
Fast charge points
Rapid charge points
Electric vehicle charging infrastructure allows consumers to charge their electric vehicle by buying electricity. Often described as the “chicken or egg” problem electric vehicles won’t be popular until charging is readily available and charging won’t be widely deployed until electric vehicles are popular.
Recently a report from the International Energy Agency, (IEA) claims to the year ending 2019 there are now 7.3 million chargers worldwide, unfortunately 6.5 million chargers are private charge points found in homes and places of work.
On the positive, the report also had good news for public charging stations, which they believe grew 60% last year:
“Publicly accessible chargers accounted for 12% of global light-duty vehicle chargers in 2019, most of which are slow chargers. Globally, the number of publicly accessible chargers (slow and fast) increased by 60% in 2019 compared with the previous year, higher than the electric light-duty vehicle stock growth.”
As shown in the table above there are now over 18,000 public charge points in 11,500 locations across the UK, these will include over 1,000 rapid charge points and new charge points are being added daily.
Rapid charge points which allow an electric vehicle to be charged in approximately 20 minutes can now be found in majority of motorway service stations across the UK.
