Additional Notes

  • The Hongqi E-HS9 carries two separate coolant circuits: one dedicated to the high voltage battery and another to the power electronics. Each circuit holds a distinct fluid volume, meaning a full service requires accounting for both systems independently rather than treating the vehicle as having a single unified cooling capacity.
  • The power electronics cooling circuit holds 8 liters across all three battery variants — 84 kWh, 99 kWh, and 120 kWh — making that circuit consistent regardless of which battery configuration is installed.
  • The high voltage battery cooling circuit capacity scales with battery size. The 84 kWh variant holds 10.5 liters, the 99 kWh variant holds 12.5 liters, and the 120 kWh variant holds between 14 and 14.5 liters, reflecting the larger thermal mass associated with higher-capacity battery packs.
  • The 120 kWh variant lists two capacity figures for the high voltage battery circuit: a range of 14 to 14.5 liters in one entry and a fixed 14 liters in another. The range value typically represents a service fill tolerance, while the fixed value may reflect a nominal or minimum fill specification.
  • Similarly, the 120 kWh power electronics circuit lists both a range of 8 to 8.4 liters and a fixed 8 liters across separate entries, following the same pattern of a nominal figure alongside a fill tolerance range.
  • The 84 kWh and 99 kWh variants, both introduced from 2021, share the same 8-liter power electronics circuit capacity, while differing in their battery cooling circuit volumes by 2 liters — 10.5 liters versus 12.5 liters respectively.
