Honda targets 50% reduction in solid-state battery weight for mainstream electric vehicles.

Honda is making progress in its pilot solid-state battery production and has revealed its plans for utilizing the advantages of this technology. One possibility is doubling the range of vehicles built on its existing EV platform. Another option is using smaller battery packs in new mass market EVs.

Last year, Honda announced its intention to build a demonstration line for the production of all-solid-state batteries. The company invested approximately 43 billion yen in this project as part of its electrification strategy, which has a total budget of US$40 billion. The goal is to begin demonstration production in Spring 2024.

In a recent interview, Honda executives confirmed their plans for EVs powered by solid-state batteries. Unlike some US automakers, Honda believes that taking the opposite approach to traditional ICE vehicles is more optimal for EVs. Instead of focusing on larger batteries, Honda believes that better access to charging is the key to reducing range anxiety.

Honda has already entered the proof-of-concept stage with solid-state technology. The company believes that this technology has the potential to reduce the weight of the battery pack by 50% due to the increase in energy density. This means that the same energy can be stored in a smaller and lighter battery.

With the lighter weight of solid-state batteries, Honda plans to double the energy volume in its existing EV platform. This would allow for increased range without sacrificing performance. Additionally, Honda is preparing for the future of mass market electric vehicles, which are expected to be smaller and more affordable. The design flexibility provided by solid-state batteries will allow Honda to develop smaller battery cases for these upcoming models.

In conclusion, Honda is making progress in pilot solid-state battery production and has ambitious plans for utilizing this technology. By doubling the energy volume in its existing EV platform and developing smaller battery cases for future models, Honda aims to improve the range and performance of its electric vehicles.
