This is the shocking moment an electric motorcycle caught fire while charging.

Footage shows the vehicle spewing black smoke before being engulfed in flames in resident Joy Sukanda's house in Nonthaburi, Thailand, on July 30.

Joy said: 'Let this be an example not to leave your batteries charging unattended. Luckily, a friend had been driving by and saw it.

'Everyone in the house is safe. The fire almost spread to the house. The best solution is not to leave the battery charging for a long time.'

The incident raises further questions about the rise of EVs and the safety of their batteries, which rely on rare earth minerals and metals mined from the remote African countryside, leaving a devastating impact on the environment.

China, the world's biggest manufacturer of batteries for EVs, has become the main source of metals such as cobalt that Western firms including Tesla rely upon.
