The 105 and 135 kWh power plants each use nine modules, the 180 kWh utilizes a total of 12. This design has resulted in Rivian's batteries being able to hold 25 percent more energy per unit volume than its nearest competitor, the Tesla Model X, according to the VP.

To keep the system from overheating, especially under heavy driving conditions, the vehicles require significant cooling capabilities. As such, each of those aluminum cold plates in between the cell layers runs on the same water-glycol solution that you'd find in a vehicle's radiator. "The flow has been optimized to make sure the maximum temperature difference between the hottest and coldest cell of the pack is less than three degrees," Rivian CEO RJ Scaringe told Wired in November.

In fact, the overall structure of the battery is cast from aluminum, which provides superior energy absorption to better protect the battery system, Farquahr said. What's more, the battery system has its own dedicated cooling system, which operates independently of the other two cooling systems for the powertrain and passenger compartment.

And, as anyone who's tried to start their car in sub-freezing temperatures can attest, extreme cold can be just as bad for batteries as high temperatures. Luckily, the R1T utilizes its cloud-based machine learning capabilities to monitor and adjust the vehicle's performance and efficiency on the fly, it can also sense the surrounding environmental temperature. When the mercury drops too far, the system activates its onboard heating elements to preserve the cells' remaining charge.

"We know that there is an optimum temperature for the cell to have most efficient use of energy to get range, and to optimize the life, the energy throughput, the life of the cell," Farquahr explained. "With the heater and chiller in the battery dedicated circuit, we can maintain the optimum temperature no matter where we are in the world, so that the vehicle will have optimum performance."

Beyond keeping the battery from slagging itself while you smoke every car off the stop line, Rivian's engineering team also had to take into consideration the R1T's primary intended use: off-roading. Because the last thing you want while bouldering is for a tire to slip and smash the full weight of the vehicle down on top of the battery pack, which is situated along the bottom of the skateboard-style frame, potentially puncturing it.

This is why the bottom of the battery is lined with a ballistic sheet. "It's a protection against those impacts, if they were to come along from underneath," Farquahr said. Additionally, the battery casing is lined with a waterproof material, which keeps the cells safe when fording up to a meter of river.

Perhaps the only drawback of the Rivian's all-electric nature is that there is no way to recharge the vehicle while in the backcountry. Sure the R1T is DC Fast Charge compatible, but that doesn't do you any good when you're 70 miles as the crow flies from the nearest charging station. And while you can easily carry a couple extra emergency gallons when driving an internal combustion vehicle, no equivalent backup currently exists for EVs -- I don't care what you saw on that one episode of Breaking Bad. Fingers crossed that future models come with optional, deployable solar panels to give the vehicle at least enough juice to get back to the interstate.
