System Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2025 Toyota RAV4, 2024 Toyota RAV4, 2023 Toyota RAV4, 2022 Toyota RAV4, and 2021 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

The inverter converts the high-voltage direct current of the HV battery into alternating current for the generator (MG1), motor (MG2) and rear motor (MGR). The inverter generates heat during the conversion process. Therefore, the inverter is cooled by a special cooling system consisting of the inverter water pump assembly, the cooling fan, and a radiator. This cooling system is independent of the engine cooling system. The hybrid vehicle control ECU assembly monitors the inverter water pump assembly, cooling fan and cooling system, and detects malfunctions.
