Hidden troubles: Electric car fire occurs mostly when charging

According to CCTV survey, with the increase in the number of electric bicycles, fires caused by electric bikes nationwide are also on the rise. In the three years of 2011, 2012 and 2013 alone, a total of 799 fires of electric bicycles were collected by fire departments across the country, killing 95 people and injuring 58 others.

In April this year, an electric bicycle shelter in a university in Fujian suddenly caught fire early in the morning. Hundreds of bicycles and electric bicycles were burned down. Some burned skeletons, and many burned electric bicycles were connected to the charger.
