Get one finished charging session as aligned 15-minute series
Battery level, wallbox power, price and one series per authenticated inverter on one 15-minute grid, over a server-determined window that pads the charge on each side. Finished sessions only: a session that is still running returns 404.

OK
Aligned 15-minute series for one finished charge, on a server-determined window.
Every list has exactly the length of buckets, and index i of each list
describes the bucket that starts at buckets[i]. A bucket with no source row is
null: the value is unknown, not zero, and the chart must draw it as a gap. A
series the charge has no source for is null throughout — an EV-only charge has no
charge_power_w, and a wallbox-only charge has no battery_level_pct.
Start of the served window, on a 15-minute boundary. The window pads the charge on each side by the larger of one hour and the distance to the nearest EV datapoint outside the charge, so the state before plug-in and after unplug is visible.
Start of the charge itself: plug-in, widened by any wallbox episode of the same charge.
Bucket start times, oldest first. The shared x axis.
Mean state of charge in the bucket, in percent.
True when the car reported charging at any point in the bucket. A pause shorter than the bucket is invisible here.
The wallbox that steered the charge, or null when none did.
Mean total power the wallbox delivered in the bucket.
The organization's trading price over day-ahead, in EUR per kWh, for the step that covers the bucket. null where the prices do not cover the bucket.
One entry per authenticated inverter of the owner, any count. Empty when they have none.
The two state-of-charge readings of a wallbox-steered charge. Empty for a charge with an EV of its own, whose battery_level_pct trajectory says the same thing better.
Width of every bucket. The cadence of the collected prices.
