Elon Musk explains Tesla’s LFP Battery strategy for US Model 3 SR+

Published

on

Tesla is giving Model 3 Standard Range Plus reservation holders the opportunity to get their vehicles sooner. For early delivery, Tesla owners can opt to receive a Model 3 SR+ equipped with a lithium-iron-phosphate (LFP) battery pack instead.

As of this writing, January is the estimated delivery date of the Tesla Model 3 SR+ in North America. However, base Tesla Model 3 reservation holders could receive their vehicle as early as September if they opt to take delivery of a Model 3 SR+ with a battery pack similar to those produced in Gigafactory Shanghai.

The one difference between the base Model 3 made in Tesla’s Fremont Factory and Tesla China’s Model 3 would be their battery packs. Fremont’s Model 3 SR+ is equipped with Tesla’s nickel-based battery cells, while Tesla China’s Model 3 uses an LFP pack.

The battery packs have slightly different range estimates, which reservation holders may want to consider before taking Tesla up on its offer. The US-made Model 3 SR+ has an EPA-estimated range of 263 miles per charge, while the MIC Model 3 with an LFP battery has an estimated range of 253 miles per charge.

Elon Musk elaborated on Tesla’s decision to start offering base Model 3s equipped with LFP batteries.

“Our intent with this pack is that product experience is roughly equivalent between nickel & iron,” he said. “I’d personally slightly opt for iron pack, as it wants to be charged to 100% whereas nickel prefers ~90%,” Musk wrote.

The slight charging differences Musk mentioned between the packs may make up for the differing range estimates between the Model 3’s nickel-based battery packs and those using iron-based cells.

There is a 10-mile range difference between the two battery packs, but the fact that the LFP cells are best charged to 100% means that owners could frequently get their vehicles’ maximum range. In comparison, Tesla notes that vehicles with nickel-based batteries are best charged to about 80%.

During the last earnings call, Musk also suggested a preference for iron-based lithium-ion cells over those with a nickel base.

“I think probably there is a long-term shift more in the direction of iron-based lithium-ion cells rather over nickel,” Musk noted.

“I think probably we’ll see a shift — my guess is probably to two-thirds iron, one-third nickel, or something on that order. And this is actually good because there’s plenty of iron in the world. There’s an insane amount of iron. But nickel, there’s much less nickel, and there’s way less cobalt,” he said.

As more automakers transition to manufacturing electric vehicles, the demand for raw materials to make battery cells to power EVs has increased. As such, EV makers want to secure their raw material supply chain in advance. Tesla’s shift from nickel-based to iron-based cells, which use zero cobalt, could help it avoid supply issues in the future.

Tesla is looking to conduct FSD tests in new Swedish city: report

The proposal appears to have been received rather positively by one of the city’s officials.

Recent reports have suggested that Tesla is looking at another city in Sweden to test its Full Self-Driving (FSD) system on public roads. The proposal appears to have been received rather positively by one of the city’s officials.

Tesla FSD tests in Sweden

FSD has already been deployed in numerous territories such as the United States, China, and Australia. However, the system is yet to be released in Europe. As per a recent report from Värmlands Folkblad, Tesla has sent a request for FSD testing to the capital of Värmland, Karlstad. As noted in a CarUp report, Tesla is already testing FSD on motorways after the company secured permission from the Swedish Transport Agency. 

The Municipality of Karlstad has reportedly not issued a decision regarding Tesla’s request yet, though lawmakers seem open to the idea of FSD being tested on public roads. In a comment to VF, municipal councilor Linda Larsson stated that FSD tests in Karlstad “sounds interesting.” Tesla’s FSD tests, if they are approved, will still use safety drivers behind the wheel who will be ready to intervene at any time. 

Tesla pledges to work with the municipality

In its request, Tesla noted that Karlstad is an interesting municipality in which to conduct its tests. The company also stated that it would conduct its operations and tests in close collaboration with the municipality, as well as local entities. Considering the municipal councilor’s comments, it does appear that Tesla might have a solid chance at attaining permission to test FSD on Karlstad’s roads. 

Tesla’s success for FSD tests in Sweden has been mixed. A few months ago, reports emerged stating that the company’s request to test FSD in Stockholm had been rejected by the Swedish Traffic Department.

“The Traffic Office is currently working on updating its approach to automation. At the same time, the city and the office are under heavy pressure from other ongoing innovation tests. Our ambition is to actively participate in and learn from the continued development in the field of automation. 

“Based on this, and in combination with the fact that the current test is the first of its kind, which entails certain risks for both infrastructure and third parties, and that it is planned to be carried out throughout the city, the City of Stockholm considers it is currently not possible to approve the implementation of the test,” the Swedish Traffic Department stated.

Waymo faces federal probe after self-driving taxi fails to stop for school bus

In a statement, a Waymo representative stated that the company has “already developed and implemented improvements” that should help its fleet avoid similar incidents in the future.

Federal regulators have launched an investigation into Waymo’s self-driving vehicles after reports that one of its autonomous taxis failed to stop properly for a school bus. 

The U.S. National Highway Traffic Safety Administration (NHTSA) stated that it’s reviewing around 2,000 Waymo vehicles following concerns that its autonomous systems may have violated traffic laws.

Waymo under review

According to a Reuters report, the NHTSA’s Office of Defects Investigation began the probe after flagging a media report involving a Waymo self-driving taxi that did not remain stationary when approaching a school bus. At the time of the incident, the school bus had its red lights flashing, its stop arm was deployed, and its crossing control arm was extended.

As per the ODI’s report, the Waymo initially stopped beside the bus before maneuvering around its front. This resulted in the vehicle passing the school bus’ extended stop arm and crossing control arm. Students from the bus were disembarking when the Waymo committed the error. The vehicle was operating without a safety driver at the time, and it was equipped with Waymo’s fifth-generation Automated Driving System (ADS).

Software fix already in place

In a statement, a Waymo representative stated that the company has “already developed and implemented improvements related to stopping for school buses and will land additional software updates in our next software release.” The spokesperson also highlighted that Waymo prioritizes the safety of pedestrians, especially children, in its vehicles’ operations.

“Driving safely around children has always been one of Waymo’s highest priorities. In the event referenced, the vehicle approached the school bus from an angle where the flashing lights and stop sign were not visible and drove slowly around the front of the bus before driving past it, keeping a safe distance from children,” Waymo noted.

Waymo, which is owned by Alphabet, operates a fleet of more than 1,500 robotaxis in major U.S. cities, including Phoenix, Los Angeles, San Francisco, and Austin. The company continues to expand its footprint and plans future operations in Tokyo and London.

A major Swedish study has revealed which electric vehicles hold their battery health the best, and Kia and Tesla came out on top. 

Swedish car broker Kvdbil initiated a test of more than 1,300 used BEVs and plug-in hybrids to determine which models retain the best battery capacity over time. Based on the study’s results, the Kia EV6, Kia e-Niro, and the Tesla Model Y were deemed the best.

Kia and Tesla lead the pack

Kvdbil’s test results are bullish for electric vehicles as a whole. The study showed that eight out of ten used electric cars still had at least 90% of their original battery capacity. Kia’s EV6 and e-Niro finished first and second in the rankings, while Tesla’s Model Y came in third. As per CarInfo data, Sweden currently has 12,148 Kia EV6 registered, while there are 48,488 Model Y.

In a comment to the media, test manager Martin Reinholdsson stated, “They are actually better than we thought. We were a bit surprised that there were so many that were this good.”

In a way, Tesla’s strong performance in the test carries extra weight since the Model Y is one of Sweden’s best-selling EVs, giving the test a much larger sample size compared to Kia’s smaller but highly rated fleet.

Battery tech, driver habits, and age all play a role

Kvdbil noted that the test’s standout results could be attributed to advanced battery management systems and careful engineering, as noted in a report from the Sweden Herald. At the same time, the study also found that factors like charging routines, driving style, and the age of a vehicle can influence capacity retention.

Rounding out the top ten were entries from Opel, Mazda, Audi, Fiat, Volvo, Citroën, and Volkswagen, as noted in a CarUp report.

This is not the first time that Tesla’s battery prowess has shown its strength. Last year, reports emerged stating that a Tesla Model S 90D from Chesterfield, UK, had traveled 430,000 miles on its original motors and batteries. Over that period, which was comprised of constant Supercharging sessions due to the car being used as an airport taxi, the Model S 90D only lost 65 miles of range.
