Is there a high chance of spontaneous combustion in an electric car

In 2019, the probability of a fire in a new energy vehicle in China was 0.0049%, and the probability of a fire since 2020 has dropped to 0.0026%. The annual fire accident rate for traditional fuel vehicles is about 0.01% to 0.02%.

Among the causes of fire accidents, power battery spontaneous combustion accounts for 31%. When rapid charging, lithium batteries with poor conductivity are prone to generate a lot of heat, and the temperature rises sharply, leading to thermal runaway.
