Trojan Technology FAQ

How does the Trojan Energy charge point work?

How does the Trojan Energy charge point work?

The CHARGE POINT is sunk into the ground, flat and flush with the pavement. It appears as a grey circular disk in the pavement. All of the sophisticated technology is underground and is not visible when there is no car charging.

The LANCE is a 50 cm height cylinder with a retractable handle, which is slotted into the charge point in order to charge. A type 2 connector cable (standard charging cable) is tethered to the lance and the other end plugs into your car.

Will the charge points add more clutter to the street?

This technology specifically aims to minimise street clutter compared to traditional electric vehicle charging equipment. The Trojan Energy charge points only take up a small amount of space next to an EV whilst it is charging. When no cars are charging, just the flat and flush sockets are left on the street.

Also, the technology has been designed with input from the Royal National Institute of the Blind (RNIB) and Disability Rights UK (DRUK) to ensure that it minimises the hazard to disabled people or those with visual impairments. The Trojan system takes into account the current Inclusive Mobility Best Practise Guidance guidelines.

What speed are the chargers?

All Trojan’s chargers provide 2 charging speeds:

  • Up to 7.4kW
  • Up to 22.1kW

The actual charging rate will depend on a number of factors such as how much electricity is being demanded from the grid and the temperature of the day (during hot days charging rates need to be lower to protect the car’s battery).

How well does the charge point cope with grit and water?

The system has been designed from the start with this challenge in mind. Our system includes a unique mating mechanism which insures that dust, grit and water will not enter the power side of the connector, however even if ingress were to occur, the system is also designed to be able to deal with / manage this.

Ultimately key breakthroughs made in this area is what has made this whole system possible and was the result of a number of years of engineering R&D. It should also be noted that over a long period of time the seals may become worn or damaged, however these can be very quickly replaced by a technician within a couple of minutes.

The entire system is entering certification and endurance testing late this year with up to 5000 make and break connections in salt water mist conditions and grit/sand etc. in order to provide further confidence on the longevity of the design.

How much does the plug unit (lance) cost?

We expect the price range to be around £200-£400, however this depends on a number of external factors. In terms of the system as a whole it is very competitive compared to the cost of installing comparable charging posts.

How much force does a vandal need to kick it with to break it?

The lower part of the lance is a strong aluminium cylinder which is essentially “kick proof”, unless the vandal is very determined and prepared to suffer a little bit! The upper part of the lance flexes to prevent kicks from damaging it while also preventing any injury to anyone accidentally colliding with it. This part of the design is at the request of a partially sighted panel we've worked with who have walked into other chargepoints. Our chargepoints are designed around pavement users as well as EV drivers.

Will there be dedicated parking spaces for charging electric vehicles?

No. Parking spaces beside Trojan connectors are not exclusivley for electric vehicles. Both electric and petrol or diesel fuelled vehicles are able to use the same space, however, there will be a connector installed every 5m throughout a single street where we install.

How much does it cost to charge with the trial technology?

The Trojan Energy charge points provide electricity at the cost of:

  • 25p per kWh up to 7.4 kW
  • 30p per kWh up to 22.1 kW

Our pricing is designed to incentivise standard 7.4 kW charging for customers. The 22.1 kW option is available for occasions when customers need faster charging.

Is my electric car compatible with the Trojan Energy charge points?

The trial Trojan technology requires vehicles to be compatible with a Type 2 charger. Most new EVs will use the Type 2 standard for charging, but to double check your car compatibility, you can ask your car dealer, or check online e.g. with Zap-Map's charging guide.

How long does it take to charge a vehicle using one of these chargers?

How long does it take to charge a vehicle using one of these chargers?

The Trojan Energy chargers charge at 2 different rates: regular (up to 7.4 kW) and fast (up to 22.1 kW), though not all vehicles are able to charge at the 22.1 kW rate. The amount of time it takes to charge your EV will depend on the model – the table on the left provides some example charging times for EVs depending on the battery size.

*The BMW i3 can charge at a maximum of 11kW with an AC charger – if the 22kW rate is selected the Trojan charger would charge at this maximum rate

**New Tesla Model S can charge at a maximum of 16.5kW – the Trojan system will only charge up to the maximum rate the vehicle can manage.

How are the chargers powered?

For the charge points to be supplied with electricity they are connected to the electricity grid from the Trojan Energy cabinet and is the source of grid connection for up to 15 charge points. Because there is one grid connection for several charge points a range of charging speeds can be offered – from 7.4 to 22.1 kW depending on how many users are charging at once. The box will be situated on the street, up against a wall and away from the pavement edge.

How many power cabinets are there?

Electrical cabinets are required near to the charge points to connect to the electricity grid and distribute the power to the charge points. There will be 1 cabinet for every 15 charging sockets, as such there will be a maximum of 2 cabinets on any one street during the trial. A major objective of this project is minimising street furniture to the greatest extent possible. As such, Trojan Energy will ensure that the cabinet is the smallest size and as unobtrusive as possible, and located in a discrete place away from the pavement edge.

How will you make sure that the local electrical grid can cope with extra cars charging?

Trojan have consulted with the local energy network operator UK Power Networks (who are a partner of the STEP trial) to ensure that all their chargers will have enough power, without having to complete a costly upgrade of the grid in the local area.

Can someone unplug my car while it is charging?

No. Charging cables lock in place when you start to charge and are only unlocked once you finish using the charge point.

General EV and charging FAQ

How far can I travel in an electric car?

Driving range for electric cars varies between models, and also depends on whether you choose a fully electric vehicle or a plug-in hybrid. Most cars have an advertised range of around 100 miles, and some are over 300 miles. For more information about electric vehicle ranges please see here.

What about rapid chargers?

Rapid chargers are not included in the Trojan trial. There are rapid chargers nearby where you can charge a car to 80% in around 20 minutes depending on the model. For information on local chargers please visit Zap Map and apply filters.

Not all vehicles can use a rapid charger - so check your car’s compatibility before planning your journey.

What if I can’t find somewhere to charge my electric car?

There are electric car chargers all across the UK and you can even use a journey planner to help you plan a long journey via charge points on the way. There are a number of these available so it worth having a look to see which one you like best:

How can I get a home charger installed?

If you have a driveway or other off-road parking you can get a home charger from many different companies. You can also get help from the government towards the cost. See information on this grant on the Government's website.

What are the cost benefits of using an EV and charging at home?

Please read this Blog Post that compares the cost of and the running of an electric vehicle to a petrol car.

I don’t have a driveway; how can I charge an electric car?

The STEP trial is helping to make this possible! When the trial is finished, Trojan Energy will begin installing many more chargers on streets around London.

If you are thinking about getting an electric car in the future and would like to suggest your street for a charger once the trial is complete, you can let us know by getting in touch or request an install.
