Segment
Charging infrastructure: power, standards and the grid connection
The two ends of this segment look nothing alike. One is a metered socket on a wall costing a few hundred and delivering most of the energy the fleet consumes; the other is a small industrial electrical installation with a grid connection, power conversion equipment and increasingly a battery to smooth the demand. This segment covers both, how the connector standards settled between them, and why vehicles are being enlisted as grid assets.
In one sentence
Charging infrastructure covers the equipment, connection standards and grid interfaces that deliver electricity to vehicles, from alternating-current home charging to high-power direct-current stations.
Alternating-current charging passes power to a converter inside the vehicle, which limits it to what that converter can handle. Direct-current fast charging puts the conversion in the charger instead, removing the vehicle's limit and moving the constraint to the battery and to what the site's grid connection can supply. That single difference splits the equipment market in two: one side is a low-cost electrical product sold by the hundred thousand through installers, the other a capital good sold by the cabinet.
At the high-power end the economics are dominated by that connection. A site with several high-power chargers is a substantial and very peaky load, and utility charges based on the highest demand in a period can dominate the operating cost. That is why so many sites now include stationary batteries: they buy energy steadily and release it in bursts.
How this breaks down
Split by the power delivered, the standards that carry it, and the direction it can flow.

What this depends on
1 of these is marked as a chokepoint: a handful of qualified suppliers, a multi-year lead time, or a single geography.
- Supply chainChokepoint
Grid connection capacity
Charging sites are large peaky loads and face the same connection constraints as any other new demand.

Power conversion equipment
A fast charger is a high-power converter; its cost and efficiency depend on the same semiconductors used in vehicles.

How these pages are written
Each page explains one technology in plain language, states what it depends on, and names companies by what they supply at that step. Company roles are described qualitatively and deliberately carry no market shares, revenue figures or rankings — those change faster than an explainer can, and a stale number is worse than none. Ticker links point at company pages on this site and are provided for reference only.
Nothing here is investment advice, a recommendation, or a forecast. A company named on a page about a technology is not thereby a good investment, and the chokepoints described are structural facts about supply chains rather than predictions about prices. Technology moves; where a page describes something as unresolved or in development, that was true when it was written.
