Dodge’s electric muscle car concept holds a lot of bold promise and big numbers, chief among them being the 800-volt “Banshee” engineering that Dodge claims will make the first EV muscle car “faster than the Hellcat in all key performance metrics.” Unfortunately, the car he is It’s still a concept design, so other details are hard to find and performance is still hard to pin down, but there are a few hints we can glean from the phrase “800V”.
First, it is worth defining the meaning of voltage in general: it is the voltage between two points. For a more realistic example, which is easy to imagine, we can define it by analogy. In the water tank system (where water replaces electricity), to increase the voltageAnd the We will make the tank longer. In other words, we will increase the potential energy of water, and as a result, the water pressure in the system will increase.
To increase power in an electric motor, you can not just pump more voltage into it. The way electric motors work, they are designed to run very efficiently at a constant voltage, and operating significantly outside these ranges results in ineffective operation at best, and complete motor failure at worst. To use a specific example, let’s take the Nissan Leaf: the engine’s optimum efficiency is 350 volts (although it can run efficiently without damage anywhere from 240 volts to 404 volts), and the battery system is designed to output a maximum theoretical voltage of about 400 volts. This is known as 400-volt architecture, and it was pretty much standard on most electric cars until recently when Porsche developed an 800-volt architecture for the Taycan. In this system, the intended output of the battery system is 800 volts, and the motor is designed to operate more efficiently at this voltage.
However, this is not how the Porsche Taycan was made faster From the paper, this does not mean that an 800 volt architecture will result in a car that is faster than a 400 volt car. Both the Taycan, the Porsche, and the Nissan Leaf use AC induction motors, where the input voltage is only a small factor in how powerful the car actually is. In an AC induction motor, the frequency (Hertz) of the power source and the construction of the motor itself is of much greater importance than the voltage applied to it. Instead, the Taycan’s 800-volt system simply means that it charges faster, and can use thinner wires (and carry less weight) than if it were using a 400-volt architecture. Motors in an 800-volt system also generate less heat, allowing them to run more efficiently and at a higher power for longer, but this power output still varies based on the motors used.
So the geometry of the Dodge Banshee 800V won’t tell us much about how fast the car is, unfortunately. CD player Asked Dodge directly for more information, but a company representative said, “The Dodge Charger Daytona SRT is a concept, and at this time we’re not getting too deep into the…800V Banshee system.”
the number that will Tell us how fast a future Dodge muscle car will be based on Banshee’s kilowatt (kW) rating. Kilowatts are more straightforward than voltages, and can be explained largely like horsepower: the higher the number, the more power the car puts in, and the faster it goes. Unfortunately, Dodge hasn’t announced it yet, so we just have to take their word for it and assume that the first electric car will be faster than hell.
