Volkswagen AG (XTRA:VOW3) is also considering listing its car charging and energy business in addition to existing IPO plans for its battery division, Chief Technology Officer Thomas Schmall told Manager Magazin in an interview published on Wednesday. Schmall said nothing has been decided yet and it would probably take up to two years before the new companies are established and actually ready for the stock market. “We also have to think in terms of overall systems,” Schmall said, referring to Tesla’s one-stop-shop complex with its own charging network, solar systems for green electricity and car insurance policies.
