Hi all, I thought I'd kill two birds with one stone in this thread. I am pretty active in keeping up with regular EVs and am generally interested in the technology. I have an extensive background in Li ion batteries so that's useful here. Anyway, I am now trying to get up to speed on the state of electric buses. I have a lot of familiarity with New Flyer but would like to know how other OEMs like Proterra and BYD compare in terms of their technology. I have scoured the internet but unearthing any specific information, especially as a non-customer, has been difficult. I was wondering if some of the fanboys on this site could help me out. Specifically, I am curious about the cell suppliers and battery thermal management for these two OEMs. BYD I know is a battery manufacturer who makes vehicles based on their technology. As I understand, they use LFP chemistry only, which is weird considering the energy density needed to achieve range for this application. Given the more stringent asks from public transport regulators for range, I would think they would want to start manufacturing NMCs (possibly the upcoming 811 chemistry) soon? Anyone know if this is a thing, or will they stick with LFP? For Proterra, I believe their supplier is LG Chem (from which they build packs). Anyone know their technology pathway to improve energy density in the coming years? Second part is thermal management. Proterra's site indicates they have active thermal management. I have not been able to decipher is BYD takes this into consideration, though. Can anyone confirm their method (if at all)? It wouldn't surprise me if they don't have their dedicated BTMS, especially considering LFPs give off significantly less waste heat compared to NMC. I understand this is a mouthful but this could be a good conversation, especially since there appears to be a lack of topics re: Ebus tech. Thanks very much in advance for any input!!
