How does Dynamic R series R50 controller Boost Amps & Volts?

[YellowBuzzaroundEX]

My mobility scooter has a Dynamic R-series R50 model, 24V 50A controller. My scooter has a 24V battery system.

The controller has a Maximum Current setting 40A, plus Boost Current setting 10A for 8 seconds. How does controller (briefly) boost current +10A? Does it use a capacitor to boost the current?

Also, the manual says the Load Compensation setting can (briefly) increase voltage +10V when needed. Does this mean it can (briefly) increase voltage to 36V? How does controller (briefly) increase voltage? Does controller use a capacitor to increase volts?

Current isn’t “boosted”, it’s less restricted. The setting removes the 40A cap that the load (motor) can draw, replacing it with a 50A cap. Doesn’t mean the motor will see 50A when you activate boost mode, it means that it’s permitted to. As in hard launch or steep incline or with heavy cargo, the load is temporarily permitted to draw “up to” 50A.

If it’s a brushed motor then boosting the voltage via a converter is fairly trivial, albeit highly inefficient. If it’s a brushless motor it’s more likely they’re utilising field weakening and referring to it as a voltage boost.

If the controller is happy with 36V, it’d be nonsense to use a 24V battery increased to 36V, you’d simply use a 36V battery if it’s 36V that you want.

It's a brushed motor. Thanks for your reply.
