Global warming is already impacting California in devastating ways. In 2018, wildfires ravaged the state, with the deadliest wildfire in history, the Camp Fire, killing at least 85 people, and the largest wildfire ever recorded in the state, the Mendocino Complex, burning almost half a million acres.1 For nearly seven years, the state has been experiencing a drought, which has greatly impacted agriculture and water resources.2 At the same time, rising sea levels threaten coastal communities with flooding, erosion and mudslides.3

We must accelerate action to reduce emissions in order to protect our state. Transportation is now climate enemy #1, the result of California’s dependence on private gasoline-powered cars.4 To prevent the worst impacts of global warming, we must reduce our reliance on cars and ensure that the cars we do use run on clean electricity.

Electric vehicles (EVs) offer many benefits for California, including cleaner air and the opportunity to reduce greenhouse gas emissions. Electric vehicles are far cleaner than gasoline-powered cars, and produce less carbon pollution and fewer of the emissions that lead to smog and particulate pollution.5

California is a leader in the adoption of electric vehicles, accounting for half of America’s EV sales.6 The trend is expected to continue as the state works to achieve its goal of 5 million zero-emission vehicles on California streets by 2030, up from 513,000 that had been sold in the state through 2018.7

In order to meet these ambitious goals, many more Californians will need to choose electric vehicles over gasoline-powered cars, which requires that owning an EV become just as easy, if not easier, than owning a gasoline car. Unfortunately, the day-to-day experience of EV drivers seeking to charge up their vehicles has a long way to go to match the ease and convenience of refueling a gasoline-powered car – especially when it comes to public charging.

Only 75 percent of the public charging stations in California that are included in a Department of Energy database are open to the public 24 hours a day.8 Only about 15 percent (750 stations) function with the ease of how we are accustomed to fueling vehicles – with the station open to the public 24 hours a day, compatible with different car types, and without requiring membership to a specific company’s network.9

People’s habits for charging their electric vehicles will be different from refueling their gasoline cars. Similar to how we charge our cell phones, most EV charging will happen overnight at home and during the day at work. Inconvenient or confusing public charging, however, still threatens to be a barrier to the mass adoption of EVs. California should use public policy tools and state investments in EV infrastructure to improve access to charging for all EV users.

Public charging is essential for the mass adoption of electric vehicles.Most electric vehicle owners need convenient access to public charging during longer trips and occasionally in daily driving. In addition, many residents of California who live in compact urban areas or multi-family housing do not have a driveway or garage and will have to rely on public charging to drive an electric vehicle. For instance, in a 2016 survey by the Union of Concerned Scientists and Consumers Union, only 54 percent of respondents reported having private off-street parking (like a garage or driveway) with an electrical outlet.10 Even people with access to charging at home will use public chargers to make up for insufficient range or to provide a range buffer for their trip.11

California electric vehicle users often run into roadblocks or confusion when charging away from home. Among the challenges they face are:

Too few chargers: Current numbers of electric vehicle chargers are insufficient to meet demand in California. Electric vehicle drivers report that chargers aren’t always in the areas where they need to charge or are often occupied. Today, the state has around 14,860 Level 2 public charging plugs (not including chargers in private workplaces) and 2,500 public fast charging plugs.12 However, to support the current number of EVs, California needs 18,500 Level 2 plugs and 3,600 fast chargers, a 24 percent and 44 percent increase, respectively.13 Meeting the state’s ambitious goals for growing the electric vehicle market will require even more chargers. By 2030, the state will need approximately 180,000 Level 2 plugs and 35,000 fast charging plugs to support the goal of 5 million zero-emission vehicles (see Figure ES-1).14

Chargers that are not available to the public: Many charging stations can only be used by patrons of a business, by paying a fee for parking, or during certain hours. According to the Department of Energy’s database on electric vehicle charging stations, only 75 percent of public stations in California are open to the public 24 hours a day.16

Incompatible chargers: Certain chargers are not usable by some types of cars, with some fast-charging plugs (CHAdeMO) only working for Asian cars, others (SAE Combo) working on European and American cars, and Tesla’s proprietary connection only working on Teslas. For instance, in downtown San Diego, an area with dense multi-family housing, there are only three fast chargers. One charger works with U.S. and European models, one works with Asian car models, and one works for Teslas.17 Effectively, all electric vehicle owners in downtown San Diego, and those traveling into the city, have access to one fast charger.

Different proprietary networks: There are at least nine networks of EV charging stations in California. For an EV driver to use a network operated charging station, they often must be a member of that system or have the company’s app downloaded. This poses a challenge for EV drivers to find and use chargers.

Opaque pricing and multiple payment models: EV networks offer many different payment methods, including through a mobile app, credit card and in-vehicle purchasing. Some networks require purchases to be made within the app. Some stations charge a flat fee, some charge based on the amount of electricity used, and others charge by the length of time the car was charging. The cost of charging is not always clearly marked at the chargers, leaving drivers guessing how much they’ll end up paying. Comparison shopping across payment metrics is very challenging for the average EV driver looking for a charge, particularly when compared to the ease of understanding the standard metric of dollars per gallon at gas stations.

In order to meet California’s electric vehicle goals and replace gasoline-powered trips with electric-powered trips, people will need more convenient options for public charging.

The good news is that smart public policies can help streamline how we charge EVs, making it easier for more Californians to participate in the electric vehicle revolution.

There are five key strategies California should pursue to improve EV charging in the state and maximize the potential of electric vehicles:

1. Expand access to electric vehicle charging by supporting and requiring the installation of more public stations. The state and local can expand access by installing charging on public property, including parking lots at government buildings, schools and curbsides. Public funds and public property should be used preferentially for stations that are open to the public, operable by all users regardless of network membership or car manufacturer, and that have clear, fair rate policies. Entities in California can help speed deployment of charging infrastructure by streamlining permitting and expediting utility interconnections. By incentivizing the development of charging stations that are available to the public, people will have access to more chargers, alleviating some of the usability challenges.

2. Ensure interoperability between stations so EV drivers can seamlessly use and pay at any station, regardless of which company owns or operates it. Interoperability has been standard in Europe for many years, with high competition among companies facilitating connections between stations. California’s Electric Vehicle Charging Open Access Act, the implementation of which is being planned now, requires interoperability capabilities on all public charging stations (whereby EV drivers can use any station regardless of network operator).18 However, the law still depends on individual companies entering agreements with each other to allow cross-network usage, creating a patchwork user experience. Entities in California should encourage interoperability agreements between companies, including by requiring that rate-based utility investments in EV charging and stations using public funding be interoperable.

Drivers also need a standard way to pay at any station. Drivers know that if they pull up to any gas station or parking meter, they can pay by cash or credit card. Drivers similarly need to know they can pay at any charging station with one form of payment, whether it is a fob or card that works at all stations or a credit card. The proposed implementation plan for the Open Access Act requires that all charging stations use credit card readers. The state should continue monitoring EV charging payment options and periodically evaluate other options to ensure that anyone who chooses to drive an EV can easily pay for a recharge.

Finally, the state should improve price transparency at chargers so that consumers can easily make price comparisons, like they can with dollar-per-gallon pricing at gas stations.

3. Require open data from charging companies so EV drivers can find all available charging stations through one site or app and know whether the charger is being used. Companies that receive public funding, utility investment, or install stations in public spaces should be required to disclose real-time information about station availability and pricing so drivers can access that information in one location.

4. Enforce the state law that requires EV charging spaces to be occupied only by charging electric vehicles. Cities should work to enforce California’s law that EV charging locations are only for use by charging EVs, not parked EVs, hybrids or gasoline vehicles. That will help ensure that charging stations are available for people who need to charge.

5. Promote mobility options such as electric transit and fleets of shared electric vehicles so people can take advantage of the EV revolution without having to personally own a car. The goal of California’s electric vehicle efforts should not be to sell cars but to expand the number of miles people drive on electric power and reduce the number they drive in gasoline-powered vehicles. The state should encourage and promote programs that give people shared access to electric vehicles when they need them.
