OnBoard Computer
Hi everyone!
Please, could someone help me, I wonder what the onboard computer is ? What it do ? I have seen there are many models (or part numbers), and some of them fews things (wires) had changed, is that true ? Someone knows how many types there are ? Why it sense the current going to the control PWM ? Thanks for your attention! Cláudio. |
Re: OnBoard Computer
are you speaking of a specific cart or just knowledge of what the controller is?

It do the following: It controls the charger and monitors battery pack voltage to properly turn the charger on and off as needed while the cart is plugged into the charger. It also supplies power to the controller. The reason it do this is because it's got a safety feature built in that won't allow the car to run while charging. The onboard computer turns off power to the control circuit of the controller while it's charging. The reason for different part numbers is due to the fact that there are so many different model cars with different battery configurations. |

Hi.
I saw many clubcars manuals, and in the most of them the OBC is has some kind of diference. And would like to know how it works. thanks |

Re: OnBoard Computer
Yes it turns the relay on and off when necessary. Newer versions of the OBC will turn off and sample the pack voltage more often than older models throughout the charge cycle.
Different OBCs perform the solenoid lockout features different ways. Some kill the negative to solenoid. Some kill the positive to controller. It runs to the controller post because it's used as a junction block for all of the main negative wires. It helps keep the terminal of the battery from having so many wires on them. The reason it runs through the center of the OBC is because that's where the voltage sensor is located. Around the edges of that hole that's in it. |

Re: OnBoard Computer
David, so sorry for too many questions... and I am very glad you are helping me to understand.
If I change the batery pack, if I used another one with diferent capacity, it makes diference to my OBC ? |
Re: OnBoard Computer
Yes. The software version is designed to properly charge a certain configuration. Let me know what you've got and what you want and I'll provide you with the correct part number.
