Real-World: How to Create More Torque in an EV
Torque = rotational force, and in EVs, it’s all about how efficiently you deliver current to the motor. Here are the main ways to boost it:
1. Higher Voltage System
-
More voltage = more current (within thermal limits), which feeds the motor harder.
-
Think 800V systems like the Porsche Taycan vs. 400V in a standard EV—faster torque delivery.
2. Bigger or More Powerful Motor(s)
-
A physically larger or dual motor setup (front and rear) generates more torque.
-
Tesla’s “Plaid” mode uses tri-motor setups for bonkers acceleration.
3. Gear Reduction
-
EVs usually have a fixed gear ratio, but you can tweak that ratio for higher torque at the cost of top speed.
-
Think of it like mountain bike gears—low gear = more torque, slower speed.
4. Improved Motor Cooling
-
If your motor runs cooler, you can push it harder for longer.
-
Water cooling, phase change systems, even liquid nitrogen (in extreme race apps).
5. Software Tuning (ESC & BMS)
-
The Electronic Speed Controller (ESC) and Battery Management System (BMS) can be tuned to allow higher current delivery—basically, uncorking the motor digitally.
6. Use Permanent Magnet Synchronous Motors (PMSM)
-
These give you more torque per amp than older induction motors. More efficient, more twist.
