What are the reasons for communication failure in Mercedes-Benz battery sensors?

[Jimenez]

The reasons for communication failure in Mercedes-Benz battery sensors include battery failure, battery sensor failure, and alternator failure. Solutions for battery sensor failure: By adding water immersion monitoring probes, humidity monitoring can be performed on buried battery packs, with alarm prompts set up for timely handling to prevent damage to the battery packs. Install temperature sensors on the batteries and set up over-temperature protection. When the temperature reaches 40 degrees Celsius during equalization charging, the system will automatically switch to float charging. Avoid continuous high-current charging that leads to battery overheating; appropriately extend the periodic equalization charging cycle to prevent frequent high-current charging, which can cause battery overheating and damage. Solutions for battery failure: Sulfation of plates: For mildly sulfated batteries, a low-current, long-duration charging method can be used to resolve the issue. Active material shedding: For lead-acid batteries with minor active material shedding, if the sediment is minimal, it can be cleaned and the battery can continue to be used. Corrosion of plate grids: For batteries with mild corrosion, if there are impurities in the electrolyte, the electrolyte should be drained and repeatedly rinsed with distilled water.
