Traction Battery, Electric Drive Motor and Cooling Circuit
Traction-battery and electric-motor entries sit within the electrical and energy-storage groups. Cooling equipment is indexed separately, so electrical-drive references should be read alongside the cooling topics relevant to the component.
The contents also retain the original Volvo functional-group labels. A broad group label alone should not be taken as confirmation that a particular engine or drive arrangement is fitted.
