Additional Notes
- The Honda E, ZC7 (EU) uses two separate coolant circuits: one dedicated to the high voltage battery and another serving the power electronics, each with its own distinct capacity range.
- The high voltage battery cooling system carries a capacity of 5.32-5.47 liters across both the E and e Advance trims for 2020-2024, a relatively narrow range that reflects a tightly controlled thermal management volume for the battery pack.
- The power electronics cooling circuit holds considerably less fluid, with a capacity of 1.66-2.42 liters, a wider proportional spread that suggests greater variability in how fully the circuit can be filled depending on air purging during service.
- A capacity expressed as a range rather than a fixed value typically indicates the difference between a minimum serviceable fill and a maximum system capacity, accounting for residual fluid and bleeding efficiency during a coolant service.
- For the E trim, both the high voltage battery and power electronics cooling systems carry a check interval of 20,000 km or 12 months under normal use conditions, whichever comes first.
- The e Advance trim shares identical capacity figures with the base E trim for both cooling circuits across 2020-2024, indicating no mechanical differentiation between the two trims in terms of coolant system volume.
- No service interval data appears for the e Advance trim in either cooling circuit, whereas the E trim lists a 20,000 km or 12-month check interval for both circuits under normal use.
