US Environmental Protection Agency(EPA) test documents showed that Rivian R1T didn’t have any heat pump. Also, the peak DC charging rate also seems to be different than claimed. The documents were posted on Rivian Owner’s Forum and it showed some interesting tidbits about Rivian’s vehicles.
The numbers show interesting things, the vehicle is equipped with 11.5 kW onboard charging. While the DC fast charging peaks at 210kW. In March the company stated that the vehicles can charge over 210kW and also stated that they target 300kW for future vehicles. There is no point in reaching conclusions because the average value might still be very high. With a battery capacity of 135kWh, the peak values are not the highest.
Furthermore, there is no heat pump in the vehicles. Where the document stated under heat pump as “N/A”. There are also details about the weight of the vehicle, R1T curb weight is stated to be 6,949 lbs (3,152 kg) and R1S at 6,916 lbs (3,137 kg). The nominal capacity of the battery is 360 Ah and the battery is 135kWh with 9 modules consisting of a total of 7,776 2170-type cylindrical cells. The voltage values range between the values between 216 V and 459 V. As there was some discharge energy of about 125 kWh and 128 kWh, the usable battery capacity could be 5-7.5% lower.
The features as specified in the documents are as below for R1T,
EPA: 314 miles (505 km)
400+ miles (644+ km) version (January 2022)
250+ mile (402+ km) affordable version to follow
Battery capacity of about 135 kWh
9 modules, 2170-type cylindrical cells (7,776), supplied by Samsung SDI
voltage: 216-459 V; capacity: 360 Ah
0-60 mph (96.5 km/h) in 3.0 seconds
quad motor, all-wheel drive
on-board charger: 11.5 kW (AC Level 2); up to 25 miles of range per hour of charge
DC fast charging: up to 140 miles of range in 20 minutes (up to 210 kW)
wading depth: 3+ ft (more than 0.91 m)
curb weight: 6,949 lbs (3,152 kg)
towing capacity: up to 11,000 lbs (4,990 kg)
However, it should be noted that the specs listed in the EPA test documents are for the 2022 Rivian R1T and R1S specifically. Taking into account that the company has spoken about upgrading its rapid chargers earlier this year. Also, the fact that they talked about the design of the vehicles is being improved on a rapid basis. There is a good chance that succeeding iterations of the flagship all-electric pickup truck and SUV may have improved in the current vehicles. Like the peak charging rates that could stand toe to toe with some of the best in the industry today.
