Does anybody know how do those 24v electric scooters work
Electric Scooter
I have just been given one of those little electric scooters. The type on which you stand on a small platform and the motor kick-in after it exceeds a certain speed. I am not sure who makes it. It has a very 1970's Russian build quality to it! Anyway, I put a picture of it he http://www.tecno.demon.co.uk/electric_scooter.jpg I dismantled it and found a 24v 4A sealed lead acid battery, a small relay board and a motor. My question: By what mechanism does the scooter trigger into action above a certain speed? And its fault symptoms: The scooter seems to have very low power. the battery seems OK but the slightest load applied to the motor causes it to cut-out. Any suggestions? |
When lead acid or gel batteries go weak, they have trouble to deliver
current under load. A common problem is that the battery goes too weak, and there is not enough torque from the motor. To properly test the battery, you must do a load test on it, and not a simple voltage reading. -- Jerry G. ===== "Peter" wrote in message ...
