Brouwer quoted in NYT article

AirUCI faculty Jack Brouwer is quoted in a January 17th New York Times article on the effects of very cold weather on electric car batteries. Electric vehicles have two batteries: a low-voltage and a high-voltage. In particularly cold weather, the lower-voltage, 12-volt battery can also lose charge, like it does in traditional vehicles. When that happens, the EV cannot charge at a fast charger until the low voltage battery has been jump-started. “It ends up being very difficult to make battery electric vehicles work in very cold conditions,” Jack said. “You cannot charge a battery as fast or discharge a battery as fast if it’s cold. There’s no physical way of getting around it.” Other colder countries, however, have taken steps to address this issue.  Read the article
