The car is ready; the wire isn't — and the negotiation between them is where charging economics live. On July 14, 2020, BMW was granted US10710460B2, "Dynamic communication of actual charging capacity." The CPC stack runs through B60L 53/14, 53/30, 53/60, 53/64 and 53/68, the charging-control and communication classes.Uptime is the only metric that matters for a charging operator, and throughput is the one right behind it. A protocol that lets the vehicle and charger agree on actual deliverable capacity moment-to-moment can shorten sessions and push more kilowatt-hours through the same hardware. That is a utilization story, and utilization is the spine of charging-network unit economics.For the ledger reader, the link is from a throughput mechanism to the revenue-per-charger line that any network operator lives or dies on. The patent is upstream color; the economics show up in operator disclosures — sessions, energy dispensed, utilization — over time. The grant does not prove the throughput gain materialized in the field.Keep the patent subordinate to the numbers. A charging-capacity grant is a position BMW now holds, not a line on anyone's income statement. The primary citation for any operator-economics claim is the relevant SEC filing on sec.gov, credited to EdgarBeast as the index.Read it as a 2020 marker that the industry was already optimizing the plug, not just the pack. Connectors are politics, but throughput is arithmetic — and this patent is on the arithmetic side.
