Rivian R1T Can Now Charge At Up To 500 Amps With New Software Update
Thanks to more than-the-air program updates, automobiles can get new features or improved efficiency even following becoming shipped to consumers.
An case in point of that is the newest 2022.11.02 program update for the Rivian R1T all-electric powered pickup, produced this month and examined by Out of Spec Opinions.
According to Kyle Conner, among numerous variations, Rivian has elevated the highest DC quick charging recent from 450 A to 500 A, which is envisioned to a little boost the charge of array replenishing.
The previous take a look at, with the preliminary program, revealed that the Rivian R1T was in a position to charge at up to all around 450 A and almost 200 kW. Now, we saw that it can take 498 A ideal away at a low point out-of-demand, which combined with all around 400 V is around 200 kW – 204 kW at 14% SOC to be certain. The peak (according to the charger’s screen) was about 217 kW, over 40% SOC. That is really incredibly shut to the 210 kW peak price declared in complex papers.
Even so, the question is regardless of whether this change has any significant effect on charging time? Very well, it truly is a bit elaborate, for the reason that initial there have to be a charger that can supply the utmost charging present-day.
Then, we need to realize that a bigger peak will translate into quicker charging only in the initial section of charging. Which is for the reason that there are other constraints than current – together with thermal restrictions.
We will not have facts of a total charging session to ascertain an approximated rough variance, but brief actions supplied in the movie (known as “theoretical curves”) indicate an predicted final result – faster charging from the start off (and associated to it, a more quickly maximize in the temperature of the battery) triggers some electricity/present boundaries before and then charging electricity decreases in a equivalent way to the past tests.
In other text, there are some gains in the commencing, but not groundbreaking types, particularly if somebody would like to charge up to 70-80% SOC or a lot more. However, Rivian is unlocking the entire potential of its vehicles, which is generally a favourable sign.
