BYD is making a play for a bigger share of the electric vehicle battery market, as local media reported on March 25 that Nio is currently testing BYD’s lithium-ion batteries for use in its electric crossovers, citing people familiar with the matter. Smartphone maker Xiaomi also recently reached an agreement with Fudi Battery, a spin-off of BYD, to test and validate its first car with the automaker’s so-called blade batteries, which boast less risk of overheating than cobalt batteries, according to the report. The companies declined to comment on the report. [36Kr, in Chinese]
