By the way of releasing the money report for Q4 2021, Rivian announced that it proceeds “considerable investments” in up coming-era automobile platforms and in-automobile systems.
The organization outlined what is coming up coming in terms of complex options, so let us consider a appear.
A person of the largest matters seems to be a proprietary 800-volt architecture (when compared to 400 V utilised currently).
It means that the new battery units will have a nominal voltage of about 800 V (the value depends on the state of demand and could possibly vary by 100-200 V).
This new architecture will carry:
- a new in-dwelling family of generate units for equally Dual and Quad-Motor configurations
- an built-in on-board charger, DC to DC converter, and DC to AC converter, in which the ability levels of the DC-AC and AC-DC are bi-directional and share semiconductors, magnetics, and the controller.
In other words and phrases, Rivian is going all-in in conditions of vertical integration.
We previously heard about the upcoming new, twin-motor, all-wheel-push Rivian electric vehicles. They will be available at a comparable rate to the existing quad-motor versions due to the fact the quad-motor versions turned additional highly-priced (for new consumers).
The presently utilised quad-motor program is primarily based on the Bosch-sourced electric powered motors, even though the drive models were engineered and are created by Rivian.
Rivian Quad-Motor generate
Rivian Twin-Motor drive
The approaching Rivian solitary-motor travel units can be employed for two-wheel-generate purposes, as effectively as for all-wheel-push apps (dual-motor with just one motor per axle).
Rivian declared that as of March 8, 2022, it has created in excess of 100 pre-manufacturing units of the new travel models.
The company expects that sequence output of the new solitary-motor push units will start later this 12 months and, at initially, will be utilised in the Rivian EDV vans by the conclude of 2022.
“As of March 8, 2022, we have crafted more than 100 pre-generation units of our new drive models on our pilot manufacturing line and are executing validation screening for both customer and business auto programs. The construction of the entire generation line for this new family of travel models is currently underway.”
The plan incorporates:
- Rivian EDV (by the stop of 2022)
one motor front-wheel push
twin motor all-wheel generate
[currently uses R1T/R1S’s drive units]
- Rivian R1T/R1S
dual motor all-wheel generate in the next half of 2023
[currently only quad-motor all-wheel drive]
A extremely interesting factor is that the forthcoming new Typical battery pack will use LFP battery cells (compared to higher-nickel chemistry utilised at the moment in the Big battery pack).
Rivian announced that at first, the new alternative will be applied in the EDV vans:
- Rivian EDV
Typical battery pack: 2022
- Rivian R1T/R1S
Common battery pack (assortment of around 260 miles): 2024
[currently only Large battery pack – about 135 kWh and range of 314/316 miles EPA]
the R1T will moreover get a Max pack (in 2023) for far more than 400 miles of assortment
“In addition to our Twin-Motor, we announced the Common battery pack, which we system to make the most of in the RCV system beginning in 2022 and R1 system in 2024. We made this new pack architecture to use LFP cells. Expanding our cell and pack know-how roadmaps to include each substantial nickel cells as nicely as LFP cells will extend our obtainable provide even though minimizing expense.
We imagine our professional shoppers will see related everyday array capabilities with LFP chemistry, and this chemistry supplies meaningful cost savings for us.”
Right here is a transient summary of the lineup:
The deficiency of a warmth pump in the Rivian R1T and Rivian R1S was a tiny disappointment, but in accordance to the most current report, the enterprise is “establishing a warmth pump-primarily based thermal procedure for enhanced chilly weather conditions effectiveness.”
Between new alternatives, Rivian outlined a bi-directional home charger and home energy goods (which may herald a home battery pack), and a more potent infotainment processing.
“We also carry on to build our portfolio of charging and energy products to broaden outside of the DC chargers for the two Rivian Adventure Network and Fleet charging to consist of our bi-directional household charger and property electrical power solutions.
Beyond powertrain and charging programs, we are also acquiring an improved network architecture and simplified electronics topology, much more potent infotainment processing, expanded autonomy notion sensors, and our up coming-era autonomy compute system.”
All round, it looks that Rivian has its fingers comprehensive of operate and is increasing in all directions.
