Live German EV charging prices from OCPDB - #194
Conversation
BNetzA's private sweep becomes BaseScraper.sweepEvRows, with the prefixes it retires taken from a shared list in germany-ev-source.ts. No behaviour change.
New nullable fuel_prices.ev_fees JSONB column. Scrapers can now pass evFees and reportedAt per price; batches without them write the same SQL as before. EV prices are checked per kWh (EUR 0.10–2.00) instead of against the per-litre bands.
The EV queries in /api/stations, /api/stations/nearest and /api/route-stations join each charger's latest EV price instead of returning NULL, and pass ev_fees through as evFees. The station list shows its average in /kWh for chargers.
Priced chargers show €/kWh, their power, and any per-minute or per-session fees. A session fee that varies lists each option with when it applies. Unpriced chargers say the price isn't published. Adds 4 strings in all 17 locales.
PUMPERLY_DE_EV_SOURCE=ocpdb pulls Germany's chargers from the Open ChargePoint Database (MobiData BW): the BNetzA register merged with operator feeds, priced with ad-hoc tariffs (gross €/kWh, session and per-minute fees). Tariffs from feeds that failed or went stale are ignored. A run fails rather than wiping the current prices when feed health can't be read. BNetzA stays the default.
It contains the BNetzA register and is the only German source with prices. PUMPERLY_DE_EV_SOURCE=bnetza or =ocm switch back. On its first healthy run it retires the bnetza- and ocm- rows.
When chargers on the route have prices, the EV planner only considers priced chargers. Each stop costs kWh × price + the session fee, using the highest fee when it varies. The plan shows a cost per stop and in total, and the value-of-time input appears. Routes with no priced chargers keep the time-only plan.
Document the OCPDB scraper (merge, tariff choice, VAT, fees, feed health, cleanup), the ev_fees column, the new env vars and the EV price range. Pages that said chargers have no price now cover the priced German chargers: map, popup, route list and charging planner.

Checks: lint, tsc and build pass, and all 883 tests pass. A read-only replay of the live feed today gives:
Memory: peak RSS is down to about 553 MB from your 626–796 MB, but not to the ~108 MB you saw. Tariffs, associations and locations still download at the same time, 4 pages each. Fetching them one after another should bring it down further, at the cost of a longer run. I can add that here or in a follow-up, whichever you prefer.

🟡 Minor · Update the merge rule: it no longer applies to register-to-register merging. · ev-sources.md:224
docs/data/ev-sources.md:224
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winUpdate the merge rule: it no longer applies to register-to-register merging.
The code in
src/scrapers/ocpdb.tsmerges register locations (bnetza_api) only when they share the same 5-decimal station key. The 25 m radius applies only when a feed location merges onto an existing pin.Line 224 says all locations within 25 m merge. A reader will conclude that two register sites 10 m apart become one pin, but the code keeps them separate (see the test "keeps register sites a few metres apart separate"). Document both rules.
📝 Proposed doc fix
-- **Locations within 25 m merge into one pin.** A charger reported by its operator is often in the register too, under another operator name and a few metres away. When the register lists the charger, its location anchors the pin, so the coordinates are the official ones. The station id is built from the anchor's coordinates. +- **Operator feed locations within 25 m of a pin merge into it.** A charger reported by its operator is often in the register too, under another operator name and a few metres away.

Unpriced chargers went into a priced EV plan at 0 per kWh, so the planner treated them as free. In Germany about three in four OCPDB pins have no price, so plans picked them wherever they could and the total came out far too low. They now compete at the median price of the priced chargers that pass the filters. Their stop shows kWh only, and the plan shows a total only when every stop has a real price.
…hor pins by position - One unparseable record failed every run, so a single bad location from a feed would freeze Germany's prices and sweep until a release. Bad records are skipped and counted again; the run fails only when more than 0.5 % of a collection does not parse, which means the feed's shape changed. - The 1.00/min cap let fees like 0.40/min from minute 0 and 0.60/min after 5 min onto the map. Real blocking fees run 0.05-0.24, so the cap is 0.30. - Pins anchored on upstream order, which the API does not promise, so two nearby feed sites could swap anchors and re-mint the pin's id (breaking shared links). Equal ranks now go by coordinates.

…t match for time fees - When no EVSE at a pin's top power had a price, the cheapest EVSE of any power stood in, so 101 DC pins showed an AC rate next to "150 kW" (Mer, ENTEGA). The stand-in must now be of the same class (DC from 50 kW); a DC pin with only an AC price stays unpriced. - Chargecloud lists an always-on TIME 0.00, then the real fee after 4 h, then always-on copies of the fee. We took a copy as the fee and showed 0.06/min from minute 0 on 251 pins. OCPI takes the first always-on TIME element, so later always-on ones are now ignored.
… price A priced charger whose detour had not come back yet still switched the plan to money and set the stand-in price, though the plan itself could not use that charger. Only chargers the plan can use count now.
The scrapers run inside the app and Node caps its heap at about half the container limit. With 512M the heap runs out while Germany's EV source runs next to other scrapers, which is how the app gets killed.

Thanks, the round of fixes was spot on. I re-ran the end-to-end check, found a few more things and pushed them here so we could merge today:
The final run on today's feed gave 77,078 stations and 25,468 priced. The handover retired exactly the ocm-/bnetza- rows, a repeat run changed nothing, and lint, tsc, the build and all 891 tests pass. |
Adds the Open ChargePoint Database (MobiData BW) as Germany's EV source: the BNetzA register merged with the operators' own feeds, with ad-hoc €/kWh prices and the session and per-minute fees on top. No API key.
