BERLIN (Reuters) – Volkswagen (ETR:) is preparing its energy and charging division for outside investors, the carmaker’s board member in charge of technology said on Friday, adding he was open to different options for a possible standalone future for the unit.

“We always prepare in such a way that we also have equity stories … so that we can also focus on external capital inflows,” Thomas Schmall said at an event in Berlin when asked about a possible listing of the business.

“And we’re open.”
