How Do All-Electric Cars Work? | Electrified Powertrains Part 5 | Toyota
– [Narrator] Toyota’s electrification leadership, spans decades and its vehicles are proof of this mastery. Its newest electrified powertrain, complements its current lineup, which include hybrid electric, plug-in hybrid electric, and fuel cell electric. This battery-electric system blends responsive performance and zero emissions, all in one exceptionally versatile package.
As part of Toyota’s Beyond Zero vision for a carbon-neutral future and more, the battery EV system, helps make electrification accessible to all. By choosing one of Toyota’s many low and zero emissions vehicles, everyone can help drive even more electrified miles and help reduce carbon emissions. That’s driving change towards a brighter tomorrow,
And that’s our Beyond Zero vision. Let’s take a closer look and see how the innovative battery EV powertrain operates. Unlike a hybrid EV, plug-in hybrid EV or fuel-cell EV system, which include a combustion engine or a fuel cell stack and a fuel tank, a battery-electric powertrain makes use of a single or multiple electric motors and a high-capacity battery. Press the push button start and the system comes alive,
Much like Toyota’s other electrified systems, activating the onboard computers, known as ECUs that regulate and control the powertrain. These ECUs also control and maintain charge on the 12-volt battery located under the hood, which is used to power vehicle lighting, windows, door locks, and other similar features. On the other hand,
The high-capacity battery powers up via the system’s main relays. These send power to components that require high voltage, ensuring battery power is switched on safely, upon vehicle startup to avoid spiking any element of the system. In the event that a fault or collision is detected, the system main relays power down safely
To isolate the high-capacity battery, and turn off the high-voltage cables, which are color-coded in bright orange. Unlike hybrid EVs and plug-in hybrid EVs, battery-electric powertrains, use motor generators exclusively for motivation. Since there is no internal combustion engine or fuel cell stack, motor generators are the only source of motivation. In two-wheel drive vehicles, one motor generator powers the front wheels, while all-wheel drive models use two of them,
One mounted on each axle. This means that each electric motor powers the front and rear independently, allowing for improved power management at each wheel. Unlike an internal combustion engine, which generates power across a power band, electric motors respond right away when the driver presses the accelerator and are able to generate maximum torque
From a complete standstill, resulting in smooth, lag-free power delivery. Equipping a battery EV with two electric motors, not only provides extra power, it also helps better manage traction, through the precise control of power delivery when driving in inclement weather conditions. Plus, the power from the second electric motor,
Which is routed through the rear wheels, enhances the vehicle’s handling and grip in the dry. Finally, just like Toyota’s other electrified powertrains, battery EVs are capable of energy regeneration. When coasting or braking, the traction motors work as generators, recapturing wasted energy and turning it into electricity,
Which is then stored within the high-capacity battery. In addition to the normal drive selection options, Toyota battery EVs, have a regeneration boost mode, which provides increased regenerative braking and greater deceleration levels when lifting off the accelerator pedal, resulting in more energy being recaptured, while reducing the need for the driver
To press the brake pedal to slow the vehicle down Battery EVs are further differentiated when it comes to charging. Like plug-in hybrid EVs, they can be charged via a level one charger, like a 120-volt household outlet or a level two AC charger that outputs 240 volts. An onboard charger converts alternating current to direct current, allowing the battery to be replenished
To 100 percent charge overnight through a level two charger. For faster charging times, battery EVs can use level three DC fast chargers, found in public spaces. Since the onboard charger, doesn’t need to convert electricity to direct current, the battery can be recharged quickly, usually reaching 80 percent in an hour or less,
Under ideal conditions. However, electricity intake slows down after 80 percent to further preserve the battery’s durability. So, that’s a closer look at Toyota’s battery-electric powertrain and how it combines responsive performance with zero emissions. As part of Toyota’s Beyond Zero vision for a carbon-neutral future, battery-electric powertrain helps set the standard
For electrified mobility going forward, giving consumers more ways to reduce their carbon footprint with an electrified system to fit their lifestyles.
