It serves as a supporting argument and is intended to help distinguish between a standard designed function or component operation from an actual system fault in a DC charging customer complaint (i.e., “DC Not charging or “DC charging too slow”. Helpful “Tips and Tricks” have been included on each topic within the document that can be used as reference to aid in the diagnosis or in understanding the system. The situation involves several possible causes: 1. Limitation of charging power by the charging station or charging app configuration. 2. Decreasing charging power at a very high state of charge (SoC). 3. Too frequent DC charging attempts within a short period of time. 4. The high-voltage battery is not at the ideal temperature. 5. Ageing of the high-voltage battery.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244504-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244504-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10244504","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BMW","model":"I4","year_from":2022,"year_to":2024,"match":"exact","vehicle_ids":["2022_bmw_i4","2023_bmw_i4","2024_bmw_i4"]},{"make":"BMW","model":"I5","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_bmw_i5"]},{"make":"BMW","model":"I7","year_from":2023,"year_to":2024,"match":"exact","vehicle_ids":["2023_bmw_i7","2024_bmw_i7"]},{"make":"BMW","model":"IX","year_from":2021,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"BMW","model":"IX","year_from":2022,"year_to":2024,"match":"exact","vehicle_ids":["2022_bmw_ix","2023_bmw_ix","2024_bmw_ix"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
