the problem with PHEVs is the battery is very small, which is a longevity concern. Batteries lose charge capacity based on how many charging cycles they go through. So if you are discharging most of the battery on a daily commute you’re going to kill that battery’s capacity within a few years (like a cell phone).
A great use for the new sodium batteries, assuming they pan out as expected and can scale up quickly. While I still think the PHEV strategy is most appropriate for last decade before batteries were sufficiently developed, a cheaper, longer lasting battery can make them more compelling
