2.8 Cooling
The cooling circuit is a closed loop that supplies a glycol/water (50% distilled water and 50% glycol) mix to:
- The motor drive box to remove heat from the drive electronics
- The brake manifold to remove heat from the brake hydraulic circuit
- The enclosure water jackets to remove heat from the flywheel bearings
The heated fluid then passes through the reservoir before flowing through a heat exchanger that has seawater on the cold side. The coolant reservoir is for coolant expansion and to make filling easy. The reservoir contains a fill cap.
