The Chinese Ministry of Industry and Information Technology responsible for EV certification wants electric cars to do better in cold weather conditions. Citing reduced battery range on a charge when temperatures are low, the Ministry held a panel to coordinate the efforts of electric car makers, regulators, and researchers to serve EV drivers better in cold climates. The list of participants includes the top Chinese EV manufacturers which already hold the range-on-a-charge records, as well as academia that deals with battery chemistry research.
