What Does The EV Mode In Toyota Prius Do?

Last Updated on November 14, 2021 by Viva Elizeee

Most Toyota hybrid and plug-in hybrid models, including the Toyota Prius, come with an EV mode. The EV button enables your car to run on electric power from the hybrid battery or high-torque electric motor. EV mode is recommended only for driving at low speeds for short distances.

EV mode enables the vehicle to draw power from its battery leading to a highly efficient driving experience. Most times, the vehicle won’t have access to much power, and it can only be driven over short distances at low speeds. When the speed exceeds 25mph or the battery is low, you’ll get a beep notification that deactivates EV mode. When deactivated, the vehicle starts running on gasoline until the battery is charged or the speed goes back to normal. 

The Toyota Prius and Prius prime come with interesting driving modes that drivers love. This article will take you through what the EV mode in Toyota Prius does, how to turn it on, and everything you need to know about EV mode and the other driving modes on the vehicle.

What Is EV Mode In Toyota Prius

The EV (electric vehicle )mode helps users maximize their vehicle’s electric power and fuel efficiency. The button is located to the right of the shifter, and when turned on, the EV mode is activated, and an indicator showing EV will illuminate on display. The vehicle has an EPA estimated range of up to 25 miles on EV mode.

Once EV mode is turned on, the system delivers power based on the battery’s output range without starting the engine. The vehicle will only start the gasoline engine if the battery’s charge is depleted or the vehicle speed exceeds 84 miles per hour. 

When you press the EV button again, the vehicle switches to hybrid driving mode, and this time, the indicator will not be turned on. When hybrid vehicle mode is active, the vehicle uses a blend of power from the hybrid battery and gasoline engine to provide ample driving power and keep the hybrid battery charged. In HV mode, the driver’s input is neither restricted nor interrupted. 

Your vehicle also has an EV auto button which, when pressed, activates the electric vehicle auto mode and illuminates on the instruments display. Similar to EV mode, the EV auto also uses electric power. Still, the gasoline engine may start more frequently to provide additional power according to the driver’s needs on this mode. When the hybrid battery can provide enough power alone, the gasoline engine turns off, and the system starts running on electric power.

Do All Prius Models Have An EV Mode?

Yes, all Toyota Prius models are hybrid and therefore can run in EV mode. However, different models have different ways of turning on and using this mode. All models are designed to automatically choose whether to run on battery or the gasoline engine depending on driving speed, battery capacity, and external temperature.

The computer automatically activates the EV mode when the battery is fully charged on the first and second generation of Toyota Prius vehicles (2000-2003 and 2004, and 2009). For third and fourth-generation models(2004-2009 and 2010-2015), users can turn on EV mode by pressing a button on the dashboard when needed.
