  "requirements": "Energy is nominal battery V × Ah; starting and target charge must be from 0 to 100%, with target at least the starting value. Ideal duration uses charger DC output V × A; charger output voltage must be 0.001 to 1000 V and current 0.001 to 10000 A. Efficiency changes grid energy and cost only; duration multiplier changes time only. Electricity price is 0 to 10000 per kWh. This is a constant-rating estimate, not a measured charging curve. It does not establish charger compatibility, battery health, safe charge limits or actual completion time. Processing stays on your device in a cancellable worker with a 10-second timeout. Maximum 500000 combined input characters and 2000 records, with 30 tariffs or grades, 30 tiers per tariff and 100 depreciation years. Guided decimals allow up to six places without thousands separators. Full JSON and JSON Pointer CSV include all source inputs, units, assumptions and results; each file is capped at 2000000 characters and CSV at 200000 leaf records. All tariff totals precede the first 200 detail rows in the parking preview; other tables preview 200 rows. Software bounds are not vehicle capability claims. Results use floating-point arithmetic.",
