How Do Different Power Steering Types Depend on Battery Functionality?
Different power steering types rely on battery functionality, as electric power steering systems depend on the battery for operation, while hydraulic systems utilize the vehicle’s power supply indirectly through the engine.
Electric power steering (EPS) systems require electrical energy from the battery. This energy powers the electric motor that assists steering. If the battery is weak or failing, the EPS system may provide reduced assistance or stop working altogether. In contrast, hydraulic power steering systems use hydraulic fluid created by a pump that is driven by the engine. While they don’t use the battery directly for steering assistance, a weak battery may impact the engine’s overall performance, indirectly affecting the pump’s ability to function optimally.
Key points include:
-
Battery Dependency in EPS:
– EPS systems depend on a functional battery for the electric motor. Poor battery health can lead to diminished steering assistance. -
