But things are not so easy as they may seem. EV cars owners have several options to charge their cars today. First, and the cheapest way to charge is a home charger, many EV owners are homeowners as well, so it is the most reasonable option for them. Nonhomeowners are waiting for charges to be installed in the apartment blocks' parking. The second alternative is to charge at work because some companies offer the charging free to employees as a perk and to encourage green driving, but not many companies provide this convenience.
