Why Charging Matters
Electric vehicle adoption is constrained as much by charging infrastructure as by vehicle supply. Every 1% increase in EV fleet share requires a corresponding build-out in public DC fast chargers, home Level 2 chargers, and fleet depot infrastructure. That build-out runs 2027-2035 and cumulatively represents hundreds of billions in capex.
The Three Layers
1. Pure-play charging networks
Companies whose primary revenue is charging access or hardware:
- ChargePoint (CHPT): Largest US network by installation count
- EVgo (EVGO): DC fast-charging focused
- Blink Charging (BLNK): Smaller US operator
- Allego (ALLG): European focus
Most pure-plays have struggled with unit economics — utilization rates below 20% make profitability difficult. Watch for inflection as EV fleet grows.
2. Tesla (TSLA)
Tesla's Supercharger network is the most-utilized and most-profitable charging network globally. The opening to other automakers in 2023-2024 (GM, Ford, Rivian adopted NACS plug standard) turned Supercharger into a profit center.
3. Utilities as the infrastructure backbone
Every charger plugs into the grid. Utilities benefit as EV adoption increases electricity demand by 10-30% over 10 years in heavy-adoption regions:
- NextEra Energy (NEE): Largest US regulated utility with renewable exposure
- Southern Company (SO)
- Duke Energy (DUK)
- Constellation Energy (CEG)
Utilities get a regulated return on capex — so grid upgrades for EV charging produce 8-10% rate-base returns.
Hidden Beneficiaries
Power infrastructure equipment
DC fast chargers require big transformers and switchgear:
- Eaton (ETN)
- Schneider Electric (SU.PA)
- ABB
Semiconductor power management
SiC (silicon carbide) chips are essential for EV chargers and vehicles:
- Wolfspeed (WOLF)
- ON Semiconductor (ON)
Cable and connector manufacturers
Unsexy but essential; 5-10% of a typical charger's BOM.
Risks
- Utilization rates staying low beyond 2028 would hurt pure-plays
- Government subsidy pullbacks could delay adoption
- Competition from Tesla's network as it continues opening
- Grid constraints could slow new charger deployment
