This dischargeĬurrent opposes the battery current through lREC so that the resultant current is zero. When 2REC conducts,Ĭapacitor lC discharges around the circuit composed of lC, 1X, 2REC, and lREC. ![]() This charge is now stored on the capacitorĬurrent continues to flow in lREC until the control card fires 2REC. In less than l millisecond (.00l sec.) and 5REC shuts off. This currentĬharges the bottom of lC positive with respect to the battery positive bus. 5REC turns on and allows current to flow T4-T3, lC, lREC, 5REC to T4-T3. The control card then supplies a gate pulse to lREC turning it on to a conducting state, allowingĬurrent to flow from the battery through lREC, motor field, motor armature, sensor, and back to theīattery. ![]() The control cardĬhecks that lC is charged and unlocks the gate to lREC and 5REC. After lC charges, 2REC shuts off due to lack of holding current. The control card then supplies a gate pulse to 2REC turning it on to a conducting state, allowingĬurrent to flow from the battery through lC, lX, 2REC, motor field, motor armature, sensor, andīack to the battery. ThisĪpplies power to the control card turning on the PMT driver, which will close the selected directionalĬontactor and complete the circuits to the drive motor. ![]() Or reverse lever to either position, and then depressing the accelerator closing the start switch. The control circuit is energized by closing the key switch, seat switch, and moving the forward So if you look at the ev100zx manual, we'd be at least talking about the same page numbers, which is drawing on page 5 and explanation on page 15. Pay them now - then pay me more later - luv it.Wow, so I had no idea what was going on. I have since sold him 1 new battery & late last year when the battery died after 2 years in a low usage (1 - 2 hours per day) operation sold him a newer truck and a right sized battery charger package. He got a truck with a 595 AHC, 48 v battery & a 1200 Amp charger. I had a customer that the local "lean to" type forklift dealer sold him. If you get a charger too big you will basically microwave the battery to an early death. I'll stop right here - you question is a good one but right sizing a charger to the battery is very important. Finally, you need to know if the battery is a gel or maintenance free type battery - the require a SCR type charge (do no confuse that with a GNB SCR FLK charger - all that means for a few hunder bucks you can convert teh charger to full SCR otherwise they operate liek a ferro reonate charger) as a different charge profile for these batteries is required. A Single phase charge can be wired into a 3 phase power supply but a 3 phase chager cannot be wired into a single phase power supply - with out cahnging the charges transformers = too much $$Ĥ. The next thing you need to know is if the charger is Single Phase or Three phase. Most 36 volt charger will have an out but of 130 amp or greater.ģ. The Amp Capacity of the charger will determine the Charger out put. Charger should have an Amp Capacity + or - 20% max of teh battery AHC no more or less - personnaly I like to size the charger by plus or minus 10%. In my example 13 minus 1 divided by 2 = 6 times 125 = 750 AHC.Ģ. Take a way 1 from the last two digits & divideby 2 then multiply the result by the middle set of numbers this will = the AHC of battery at a 6 hour rate (in Europe & Asia & probably the rest of the world - use a 5 hour rate). ![]() The battery may have a name plate that will give you this, if not remove one of the inner cell connectors near the the positive battery cable (the red one) you will find a number like 18-125-13. Yes, you need to determine the battey amp hour capacity.
