    Tesla Superchargers Boost Cold Charging Speed for Model Y LFP Batteries

    Tesla is set to launch a battery heating feature at its V3 and V4 Supercharger stations. This enhancement will enable standard range Model 3 and Model Y RWD versions equipped with LFP batteries to charge up to four times quicker during winter months.

    Performance in Cold Weather

    Typically, LFP cells, like those found in portable power stations, do not perform as well in low temperatures. This might be a reason why Tesla has prioritized the Supercharger battery heating option specifically for the standard range Model Y and Model 3.

    Innovative Heating Method

    The new heating service differs from the usual preconditioning process that Tesla vehicles undergo when heading to a Supercharger. Instead of slowly warming up the battery pack, the Supercharger transmits ripple AC current straight through the individual LFP battery cells, effectively heating them during cold weather conditions.

    “This is made possible by Tesla’s vertical integration and some of our brilliant engineers,” says Max de Zegher from Tesla. He notes that this new feature might remain exclusive to vehicles that utilize CATL LFP batteries.

    Speeding Up Charging Times

    The Supercharger battery heating option can allow a standard range Model Y to get back on the road up to four times faster than previously, addressing the main issue faced by LFP batteries. Elon Musk has previously discussed the slower charging speeds of Teslas with LFP batteries in extreme conditions:

    In cold weather, LFP batteries charge at a slower rate compared to NCA batteries, and their range diminishes more than that of NCA batteries as well. It’s important to remember that both types of batteries perform poorly in cold weather, but LFP batteries are more affected. While on a road trip to a Supercharger, the vehicle will prewarm its batteries, which can help alleviate some of the slower charging issues. However, this means you may spend an additional six or seven minutes at the Supercharger during winter with LFP batteries. This could be a concern if you intend to rely on your vehicle for frequent cold weather supercharging, though it won’t affect you if you charge your car at home overnight.

    Tesla’s LFP battery supplier, CATL, now has new LFP cells that do not experience slow charging in cold conditions. However, these specific cells are not used in the standard range Model 3 or Model Y. In the US, Tesla is primarily selling only long-range options, as its vehicles with Chinese LFP cells do not qualify for federal tax incentives.

  • SK On Targets Mass Production of LFP Batteries for the EV Market by 2026

    SK On Targets Mass Production of LFP Batteries for the EV Market by 2026

    South Korea’s SK On to Begin Mass Production of LFP Batteries in 2026

    South Korean company SK On is planning to start mass production of lithium iron phosphate (LFP) batteries as early as 2026. The company aims to collaborate with major traditional automakers to provide a more cost-effective battery chemistry. SK On’s Chief Administrative Officer, Choi Young-chan, revealed this strategy, which is similar to that of Chinese counterparts.

    Expansion of Battery Supply to Major Automakers

    SK On is already actively involved in supplying electric vehicle (EV) batteries to major automakers like Ford, Volkswagen, and Hyundai. Although the names of the specific original equipment manufacturers (OEMs) have not been disclosed, Choi stated that mass production will begin once the ongoing discussions are finalized.

    Growing Adoption of Diverse Battery Chemistries

    The automotive industry is currently experiencing a surge in the adoption of various battery chemistries, including LFP. Manufacturers are striving to reduce costs and ensure a stable supply chain. This announcement from SK On provides the first detailed insight into its LFP battery strategy and outlines a timeline for mass production. Rivals LG Energy Solution and Samsung SDI have also announced their plans to target mass production of LFP products in 2026.

    Focus on Energy Density and Efficiency

    SK On, a battery unit of South Korean energy group SK Innovation, is considering the possibility of manufacturing LFP batteries in Europe or China. Choi acknowledged the challenge of competing with Chinese LFPs on cost but emphasized that the company’s focus is on energy density, charging time, and efficiency rather than price alone.

    Concentration on European Market for LFP Batteries

    Although SK On has production facilities in the United States, South Korea, Hungary, and China, the company is not currently in talks with its U.S. automaker customers regarding LFP supply. Choi explained that the high cost of building LFP factories in the United States makes it less feasible. Instead, the company is primarily concentrating on the European market.

    Chinese Dominance in LFP Production

    Chinese battery manufacturers, such as CATL and BYD, currently dominate global LFP production. They benefit from strong demand in their home market. LFP batteries from Chinese manufacturers are approximately 20% cheaper than nickel-based alternatives, making them an economical option for EVs, although they may have slightly reduced range compared to nickel-based alternatives. SK On is also working on the development of prismatic and cylindrical-type EV batteries, with notable progress in the latter, which is used by Tesla and other automakers.
