  • One of the biggest challenges with mass EV battery production is making sure performance stays somewhat flat across the entire market you’re selling them in. Typically, LiFePo batteries perform better at higher temperatures than other chemistries, at the expense of low-temperature performance.

    This works well, as long as

    1. These batteries are only in vehicles sold in warmer climates
    2. Customers never drive these vehicles into cold climates.

    #1 is much easier to enforce as a manufacturer, but customers will be pissed if they move north, and their vehicle has worse range and power.

    Li-ion has a flatter temp/performance curve, so it’s more suited to geographically larger markets like the US, where regulations require a single range number for the entire country, despite the significant climate variance
