Meet The Teardrop Trailer That Can Recharge Your EV

Video / Comments

It's essentially a $55,000 battery bank.

EVs are great at many things, but towing is not one of them. We've seen manufacturer claims and several real-world tests, and the figures just down match up.

Ford is already busy trying to fix the problem with more accurate range estimations and a navigation system that will optimize your trip, but this is not a long-term solution. Ford filed a patent for a three-cylinder ICE range extender for the F-150 Lightning, but it has yet to enter production. Meanwhile, Toyota flat-out refuses to build an electric Tundra until it has the technology to build a viable EV towing machine.

Short of towing an extra battery pack along, there's nothing to be done. That's why Colorado Teardrops created the Boulder, a teardrop adventure trailer tailor-made for EVs.

Colorado Teardrops makes some bold claims in its product video. The Boulder has a battery pack built into the trailer frame. The rest of the teardrop is simply constructed on top of the battery bank. It's a remarkably simple solution that is claimed to take your EV back to "pre-towing range or better."

The Boulder was designed to be as aerodynamically efficient as possible, so it has less of an effect on the vehicle's range. It has the same rigid structure as the manufacturer's other adventure products. The interior can be converted from a living room to a sleeping quarter within seconds.

Having a sizeable onboard battery pack means you can also power way more gear than anyone else at the camping spot.

The Teardrop is equipped with a sizeable 75-kWh battery. It obviously adds weight to the structure, but the assembly sits on a reinforced steel frame rated for 3,500 pounds. To keep the weight low, the cabin frame is constructed from welded structural aircraft aluminum.

According to Colorado Teardrops, the Boulder will be capable of Level 3 charging. If this turns out to be true, it will add 100 miles of range in 10 minutes. Taking the car's battery up to 80% will require 80 minutes, which is a long time, but at least you've got somewhere to sit.

To charge the Boulder back up, you simply charge it into your home charger or any of the available charging networks, including Tesla's Supercharger Network.

There are a few issues worth mentioning, however. The Boulder has a starting price of $55,000, roughly that of a mid-spec Ford Lightning. If you tow with the new Chevrolet Equinox EV, your trailer will be nearly twice as expensive as your car. The Teardrop only comes with a one-year warranty, and that's troubling. Automotive manufacturers have been giving their EV batteries at least an eight-year/100,000-mile warranty because replacing the battery is ridiculously expensive.

At the moment, it also can't charge on the go. There isn't a single manufacturer that allows charging while the car is moving, and that's unlikely to change. But Colorado Teardrops says that it is monitoring the situation and will jump at the first chance it gets to implement this technology.

Initial deliveries of the Boulder EV charging camper trailer are scheduled for delivery in the first half of 2023. This date may change depending on parts supplies and global supply-chain issues.
