By By 2030, half of new cars worldwide will be electric powered, the head of the Zurich-based power and automation technology company said Monday during a meeting with Wall Street Journal editors. Vehicle technology is ready, and infrastructure such as charging stations must be put in place, he said.
 
 As that happens, the power needs and storage capacity of vehicles will create an opportunity for new business models. For example, car users may get free electric power for their vehicles in exchange for contributing power to the grid. And a wide range of businesses may get into the power charging station business. “There can be new business models. We have supermarkets that buy charging stations from us,” he said.
