I have an electric vehicle with:
I would like to modify this existing setup by digitally (i.e. via an Arduino) creating a temporary 'boost' to the motor power.
I have a 36V battery which other owners of this vehicle assure me can accept a straight-swap of the 24V battery with a 36V battery for added performance.
My questions are:
In assessing the best option, my criteria are: cost, space, electrical efficiency.
So ideally minimal additional components but still efficient.
Thank you.
- 250W 24V brushed DC Motor
- 24V motor controller
- 5-pin throttle pedal (green, black, red, yellow, orange)
- 24V battery
I would like to modify this existing setup by digitally (i.e. via an Arduino) creating a temporary 'boost' to the motor power.
I have a 36V battery which other owners of this vehicle assure me can accept a straight-swap of the 24V battery with a 36V battery for added performance.
My questions are:
- What kind of control is the throttle with 5-pins? Is it PWM?
- Is it best to use an increase in voltageto facilitate the boost?
- If so, does this just affect RPM and not Torque as I have read elsewhere?
- Which of the following methods is best, and what components would I have to add in to the existing setup to achieve this?
- 'Modifying' the signal from the throttle so that during normal use, a fully-pressed throttle would give the same signal to the controller as 66%-pressed pedal. This way, with the 36V battery, I'd get about the same performance as with the 24V. Then, using the Arduino, I can 'unmodify' the throttle signal so that the fully-pressed pedal now outputs 100% again.
- A voltage regulator between battery and controller which regulates down to 24V until Arduino does something to enable the boost.
- A voltage regulator between the controller and the motor which regulates down to 24V until Arduino does something to enable the boost.
- Assuming the throttle is PWM, would this then end up in a DC voltage to the motor which has undergone PWM twice?
- Is this a problem?
- Assuming the throttle is PWM, would this then end up in a DC voltage to the motor which has undergone PWM twice?
