FA-93329 / EV charging session scheduling / Member archive

Site power profile from charge plans: merge equal levels · case 04

The profile repeats the same power level at every breakpoint.

Case contract

plan holds [start, end, kw] charging intervals ([start, end), zero-length ignored). Build the site profile as change points [[t, total_kw]] over the interval breakpoints, merging equal consecutive levels, and close with [last breakpoint, 0] unless the profile already ends at 0. Also return the start points of segments whose total exceeds site_max. Return [profile, overloads].

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: merge equal levels	`[[[3, 0], [6, 7], [8, 7], [10, 14], [11, 7], [12, 0], [13, 7], [23, 0], [29, 11], [39, 0]], [10]]`	`[[[3, 0], [6, 7], [10, 14], [11, 7], [12, 0], [13, 7], [23, 0], [29, 11], [39, 0]], [10]]`	Failed
