OBCs - On Board Computers
On Board Computers, or OBC's and we commonly call them are specific in the golf cart industry to only one brand, Club Car. Club Car has used the OBC in their golf carts since they introduced their first 48V golf cart back in 1995. The OBC is now standard equipment in all of their DS and Precedent model golf carts as well as many of their other electric utility vehicles and personnel carriers.
Most golf cart manufacturers have all of the electronic components responsible for the charging of the battery bank located within the battery charger itself. Club Car took a different approach and not only has circuitry inside the charger to monitor the charger, but also with the OBC installed into the golf cart. The OBC is responsible for monitoring how many units of energy were used and communicating this information back to the charger for recharge.
