Technical Service Bulletin LI54.10-N-078161 — 2024 MERCEDES-BENZ ESPRINTER

Complaint • "Unable to calibrate battery, see Operator’s Manual." • "Calibrate battery to ensure max. range is achieved, start charging process up to 100%". Remedy: Standard calibration is necessary. • "Calibrate battery to ensure max. range is achieved, charging time extension: start XX min AC charging up to 100%". Remedy: Special calibration is necessary. • "Battery calibration necessary, start AC charging up to 100% for state of charge: max. 15%; outside temperature: min. 15 °C". Remedy: Special calibration is necessary. Cause The eSprinter 2.0 (model series 907) is equipped with a high-voltage battery with LFP (lithium iron phosphate) technology. This stands out in comparison to the NMC technology (lithium nickel manganese cobalt oxide) through its particularly long service life but it has to be calibrated regularly to achieve a precise SOC and range forecast. Ideally, along with the automatic calibration, a special calibration should also be conducted 2 times a year. Remedy Automatic/standard calibration of high-voltage battery Conducted automatically during every charging process up to 100% and it does not need to be triggered. Requirements for special and manual calibration: • The driver can wait for the calibration-related extended charging time to be completed. • The outside temperature is at least 15 °C. • The state of charge is less than 15%. • High-voltage battery charged up to 100%. • With automatic calibration the high-voltage battery has to be charged with AC. With manual calibration, DC charging is also an option. • Check if a departure time is preset that is reached before the end of the charging time (including charging time extension) and, where possible, deactivate it. • Check if the maximum state of charge is set to 100%. • Check if, during calibration, an electrical consumer was used or if the power supply was switched on. • Where possible, avoid any strong cooling of the vehicle or re-arrange the time of the calibration until the weather conditions are more favorable.
