electric bike controller

2017-10-31 Zprávy 2 comments

There are two distinct types of controllers designed to match either a brushed motor or brushless motor. Brushless motors are becoming more common as the cost of controllers continues to decrease.

An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and…

Battery operated bicycles use rechargeable batteries,electric motors and some form of control. Battery systems in use include sealed lead-acid,nickel-cadmium,nickel-metal hybrid or lithium-ion polymer.Batteries vary according to the voltage, total charge capacity,weight,the number of charging cycles before performance degrades,and ability to handle over-voltage charging conditions.The energy costs of battery operated bicycles are small,but there can be considerable battery replacement costs.The lifespan of a battery pack varies depends on the type of usage.Shallow discharge/recharge cycles will help extend the overall battery life.
