An initial public offering planned for next year in India could be a crucial test for the country’s budding electric-vehicle market. 

India’s Ola Electric, which makes two-wheeled electric scooters, filed in late December a draft prospectus for a public listing, seeking to raise about $662 million. It will become the first EV maker to list in India and will probably draw significant interest from investors. The Softbank-backed firm plans to use proceeds from the offering mainly for the expansion of its battery cell manufacturing facility in the southern state of Tamil Nadu.
