Tesla is developing a battery trailer designed to extend the range of the Cybertruck. The company has filed a patent application in the United States for a system that increases the driving range of electric vehicles by using an external battery unit mounted in a trailer.
The concept involves additional battery packs housed inside a towable trailer connected to the main vehicle. Power management between the vehicle and the trailer batteries is synchronized, taking into account road conditions, voltage levels, and navigation data. This allows the system to conserve the trailer’s charge if the vehicle’s main battery alone is sufficient to reach the destination.
Beyond recharging the pickup itself, the trailer battery can also supply electricity to external devices such as household appliances, construction tools, or other equipment. In effect, the trailer functions as a mobile power station, significantly expanding the vehicle’s utility.
Tesla recently introduced a new all-wheel-drive Cybertruck variant with dual motors, starting at around $60,000, making it the most affordable version of the model currently available.
