Not sure why dig up the earth to mine for rare metals and only for it to cause so much inconvenience in terms of charging any EV. Who has time to find a EV station at 3am and spend 30min for it to charge?

The 70-kWh packs continued to be used after the 75-kWh packs were introduced.The current mainstream battery packs include Li-ion ternary cells, as well as LFP cells, with the former usually used in high-end models. A special case is BYD, which currently uses blade batteries based on LFP chemistry across its entire model line, including the ultra-luxury Yangwang sub-brand.Lithium ternary batteries have the advantage of high energy density and performance, but the disadvantages are even lower safety, poorer cycle life and higher cost.LFP batteries have lower cost, longer life, and higher safety, but lower energy density and poorer low-temperature performance.One of the most important drawbacks for LFP batteries is that SOC estimation is difficult, especially in low temperatures, which can lead to sudden power outages when the vehicle's indicated remaining capacity is low.In 2021, Nio launched the hybrid pack by adding 12 Li-ion ternary battery cells to the LFP pack, it said today.These ternary cells helped the LFP cells with SOC estimation accuracy corrections and created the industry's first dual-system cell BMS algorithm, the company said in the statement today.In 2022, Nio's team embedded algorithms in the control software regarding the use of LFP cells only, for which gray-scale monitoring and testing was performed, it said.After two years of iteration, a breakthrough in SOC estimation accuracy was achieved, with the error reduced to 3 percent, far better than the industry standard, according to Nio.In terms of algorithms, the 75-kWh standard range battery pack also incorporates multi-scenario SOC calibration and utilizes a variety of charging, driving, and standstill conditions for SOC estimation accuracy correction, it said.Meanwhile, Nio introduced self-discharge and self-learning algorithms to learn the self-discharge rate of LFP cells, solving the challenge of inaccurate SOC estimation accuracy of LFP cells due to consistency issues, it said.In addition, Nio's in-house developed cloud-based algorithms and training model for BMS SOC estimation data allow for more accurate SOH (state of health) estimation for individual cells, which plays a key role in improving user experience, it said.The 75-kWh standard range battery pack now uses LFP cells manufactured by CATL, whose SOC estimation accuracy is consistent with that of the hybrid pack, Nio said.","kind":null,"is_publish_news":null,"is_publish_highlight":null,"is_publish_live":null,"is_publish_wemedia":null,"editions":null,"symbols":[],"gpt_button":0},"commentList":[{"id":285325735149616,"gmtCreate":1710665777525,"gmtModify":1710666721578,"author":{"id":"4159389029106972","authorId":"4159389029106972","name":"HJKJ","avatar":"https://community-static.tradeup.com/news/default-avatar.jpg","vip":1,"crmLevel":1,"crmLevelSwitch":0},"htmlText":"Not sure why dig up the earth to mine for rare metals and only for it to cause so much inconvenience in terms of charging any EV.

incorporates multi-scenario SOC calibration and utilizes a variety of charging, driving, and standstill conditions for SOC estimation accuracy correction, it said.Meanwhile, Nio introduced self-discharge and self-learning algorithms to learn the self-discharge rate of LFP cells, solving the challenge of inaccurate SOC estimation accuracy of LFP cells due to consistency issues, it said.In addition, Nio's in-house developed cloud-based algorithms and training model for BMS SOC estimation data allow for more accurate SOH (state of health) estimation for individual cells, which plays a key role in improving user experience, it said.The 75-kWh standard range battery pack now uses LFP cells manufactured by CATL, whose SOC estimation accuracy is consistent with that of the hybrid pack, Nio said.","news_type":1},"isVote":1,"likeStatus":false,"favoriteStatus":false,"reportStatus":false,"tweetType":1,"langContent":"EN"},{"id":285232975597672,"gmtCreate":1710643147606,"gmtModify":1710643151882,"author":{"id":"3569481861842889","authorId":"3569481861842889","name":"Bobjojuki","avatar":"https://static.tigerbbs.com/2cb863319f3eeb17cb904c1be5304979","vip":1,"hat":"https://static.tigerbbs.com/0a8758340a08196056f8bc1e54805193","crmLevel":3,"crmLevelSwitch":0},"htmlText":"Great
