Governor Newsom’s Executive Order (N‐79‐20):

• Requires 100 percent of California sales of new passenger car and trucks be zero‐emission by 2035.• Electrify Freight Trucks by 2035 and Medium & Heavy Duty Fleets by 2045.

Assembly Bill 2127 EV Charging Infrastructure Assessment:

• Baseline: 700K public and shared private EV chargers are needed to support 5M EVs by 2030.• High: 1.2M chargers will be needed for the 7.5M EVs required by 2030 in CA.

Commercial EV Charging Infrastructure:

• 45,000 Charging Stations by 2025 ‐ Including 1,000 DC Fast Chargers• 120,000  Charging Stations by 2030 ‐ Including 3,000 Fast Chargers

Electrification of City and Transit Fleets:

• Mayor’s Executive Directive 25 – Electrify all new City light duty sedans in 2021• Electrify 100% of City of LA’s commercial medium and heavy duty fleet by 2028

LA100‐ Light‐duty EV charging profiles‐High projection, 2045

Vehicles charge immediately upon arrival and charge until fully charged or another trip initiated. 

Vehicles shift charging to earlier parts of the day and still achieve the same total energy charge as top row.
