Additional Notes
- The Mercedes-Benz eEconic 956.5 (EU) carries two separate coolant circuits, each with its own capacity figure — 48 liters for the high voltage battery cooling system and 28 liters for the heater cooling system.
- A 48-liter capacity for the high voltage battery cooling system reflects the thermal management demands of a large traction battery pack, where maintaining temperature within a narrow operating range is critical to battery longevity and performance.
- The heater cooling system's 28-liter capacity is distinct from the battery circuit, indicating a dedicated loop rather than a shared or branched arrangement with the high voltage battery cooling system.
- Both circuits on the eEconic 300 follow a flexible service interval governed by the on-board maintenance system, meaning coolant service timing is determined by the vehicle's own monitoring rather than a fixed mileage or calendar schedule.
