Indian ride-hailing company Ola has secured $500m from investors, led by existing backer Singapore state-owned firm Temasek. The funds will be used to fuel Ola's electric vehicle initiative, including the expansion of its fleet and charging infrastructure. The company aims to have 1 million electric vehicles on the road by 2021 and has already deployed over 10,000 EVs. Ola plans to work with local governments and other partners to build the necessary infrastructure to support electric mobility.
