The EP Tender looks like a camper’s tiny pod caravan that’s towed behind an ordinary car – but it isn’t! It is actually a mobile battery that will someday make it possible to travel hundreds of kilometers with an electric car. At present, most EVs usually don’t go further than 150 kilometers, so says the founder of EP Tender, Jean-Baptiste Segard. The battery is then empty and needs to be recharged. Segard hopes that the masses will switch to buying an electric car as soon as EP Tender’s battery trailer comes onto the market.
What motivated you to set up EP Tender and what problem did it resolve?
“I first came up with the idea of a trailer with extra capacity for the electric car like our current EP Tender when I wanted to buy an electric car myself. That was back in 2012. I couldn’t find a suitable electric car at that time. The range was not great enough for the few times a year when I wanted to travel much further. I thought it was a pity that there wasn’t a modular system around that would supplement the electric car’s battery so that I could occasionally travel longer distances with it.
At first I thought of a trailer with an internal combustion engine which might run on petrol. But in 2018, we switched to a trailer with an auxiliary battery, because then we would be better able to meet the needs of the electric car manufacturers. We will have to halve our CO2 emissions by 2030. And that is something that car manufacturers must also work towards.
150 kms of extra range
The rationale behind the battery is that you only hire it when you need extra range. Generally speaking, I think this would only be about six times a year for me. You can lengthen the range of your electric car from about 150 kilometers to 250 to 300 kilometers. You could also place a larger battery permanently in your car so that you can keep on driving. But that is far too expensive for most people. This remains an obstacle for them as far as switching to electric-powered transport is concerned.
Installing a larger battery is generally not an efficient solution for increasing the car’s range either, as most people drive just a few times a year further than an average car battery can handle. Otherwise you would be driving around with that heavy battery for no reason. You can compare the weight with that of a cow or a donkey. You’ll have these on your back seat during every short trip. Why would you want to do that if you don’t need to?”
What is the main obstacle you will need to overcome?
“It is very difficult to be taken on board in the development plans of car manufacturers. The automotive industry has been around for 120 years. And the planning cycle is lengthy when it comes to developing a new car. That said, we are in talks with a number of car manufacturers. However, a contract with any of them is yet to materialize. It is important that this happens. After all, the car manufacturers must apply for approval from the statutory regulators for use of the EP Tender system with their electric cars. They will only do that once they have our technology fitted to their cars. We cannot do that for them. As long as they haven’t got that done, there won’t be a market for us.”
What has been the biggest breakthrough so far?
“In 2018, when we switched to a battery in the EP Tender instead of a combustion engine. That way you can rely even more on sustainable energy.”
What can we expect from EP Tender in the coming year?
“Our business model must be in place by then. We are now completing a survey using data from 350,000 consumers which should show what most people would be willing to pay when hiring the EP Tender. As well as how often, where and when they could use the EP Tender. We are now putting the finishing touches to the robotics of the trailer so that it can connect itself to the car. The idea is that every 50 kilometers along the road there will be a service station where there will always be twenty EP Tenders ready to be connected. We are currently discussing the location of these service stations with energy companies. But also with private motorway operators in various European countries who have a state concession for these. They have an interest in electric cars being able to add energy in time so that they don’t end up stuck on the roadside.”
Where would you like to be with EP Tender in five years’ time?
“Then we would like to be profitable. Or at least break even. The outlook is that 40% of cars will be electric by 2030. So the demand for the EP Tender should have increased by then. By 2025, we want our trailer to be available for hire in the major European countries such as France, Germany, the Netherlands, Belgium and Switzerland. But also in Austria, Italy, Spain, Sweden and Denmark. And we want to have a foothold in the US, China and India.”
What does EP Tender’s innovation improve upon compared to products in your segment of the market?
“That drivers of electric cars can drive a long distance without having to constantly worry about their battery’s energy reserves.”
