FA-93169 / EV charging session scheduling / Member archive

Demand-response curtailment of a charge plan: overlapping events · case 04

When two events overlap the milder one can win.

Member previewVariant 4 · 3 implementations · 7 checks per implementation

Case contract

profile is planned watts per slot. events are [start, end, pct, opt_out]; during [start, end) a non-opted-out event limits power to pct percent of plan (integer floor of p*pct/100), and overlapping events apply the lowest pct. Curtailed power never drops below min(plan, floor_w). Return [new profile, total curtailed watts over slots].

Why this case matters

Depot, workplace and public EV chargers schedule sessions against prices, circuit limits and departure deadlines; a wrong decision silently strands a driver or overloads a feeder.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: overlapping events	`[[11000, 1111, 1111, 1380, 3333, 1111, 5550], 4150]`	`[[11000, 1111, 1111, 1380, 3333, 1111, 1380], 8320]`	Failed
