Electric truck maker Volta Trucks said on Tuesday it has decided to file for bankruptcy proceedings in Sweden, after difficulties at suppliers made it hard for the startup to raise funds.

Volta, which is headquartered in Sweden and has operations in the United Kingdom, said the bankruptcy in August of electric vehicle parts supplier Proterra and uncertainty over its battery supplier had cut the number of trucks it was able to produce and made it hard to raise sufficient capital.
