Is the BYD LFP Battery USELESS in Winter? (-13°C Test)

Can the BYD Seal really compete with the Tesla Model Y and other EVs in freezing winter conditions when it comes to charging speed? In this video, we find out the hard way…

The conditions were pretty harsh: it was a freezing -13°C day, and my BYD Seal had been sitting parked outside for over 20 hours with temps at the night reaching even lower levels, leaving the battery really cold.

I only had time for a quick half an hour preconditioning session (with just 20 minutes of actual low-speed driving) before pulling up to a 200kW CCS charger.

What was supposed to be a quick top-up turned into a 4-way showdown. As soon as I plugged in, the station filled up completely with a Tesla Model 3, a Tesla Model Y, and a Hyundai Kona Electric. And all data was available from each car: the charging powers and states of charge.

NOTE: This is NOT a scientific lab test – this is a real-world scenario. The charging station was splitting power between all four cars, and everyone had different SOC levels and not full charging curves of each cars were documented from start to finish.
However, seeing how the BYD Seal’s Blade LFP battery performed against the Teslas and the Hyundai in this freezing environment was pretty…. shocking! You won’t believe which car pulled the highest numbers in this brief practical test.
