Chinese battery manufacturer CATL (Contemporary Amperex Technology Co Ltd) is developing a battery system for Newton eTrailer electric cargo trailers from Germany’s Trailer Dynamics. The developers expect to bring their solution to the market of Germany and other EU countries already in 2023.
CATL will supply these trailers with its LFP (lithium iron phosphate) batteries assembled into liquid-cooled CTP modules. Such batteries are distinguished by a long life cycle, as well as an increased energy consumption of about 155 W / kg.
A 300 kWh battery will weigh about 2000 kg, which is not so much for a truck trailer, but it can provide an enviable power reserve.
At the same time, Newton eTrailer semi-trailers contain not only batteries, but also electric motors, so that they can potentially not only “help” the tractor in motion, reducing energy consumption, but also accumulate energy due to recuperation during braking and driving downhill.
To ensure the minimum energy consumption, the semitrailers will be made as aerodynamic as possible – judging by the images, even the wheels will be covered with special panels.
Recall that we have already talked about a trailer with batteries to increase the range of electric vehicles, but then we were talking about a compact Renault Zoe electric car, not a truck.
