Zivan NG3 battery charger diagrams

not car, is electric EV motory cycle or EV moped (it has pedals)
batteries are charged and then load tested with a tool called the same
powered by 1000-watt motor powered by a 48-volt 17AH Samsung battery.
SAMSUNG Lithium Ion 48v
not 12v.
so bad charger, wrong battery put there or battery is bad
we cant see what IS there blind so learn to test the battery first
they fail at 1000 cycles, (short lived they are)
you year told or how old battery is.

any shop can test the battery and charger that came with the bike. let them?

I would like to see a wire diagram of my battery charger Schumacher model #se-5212a-CA

Yes, But. 2 pack so 6volt each, I will assume standard lead acid batteries as the is common, and that is what the pic shows. depends on what you call standard charger, I would not do it with my 40 year old standard charger, although at a push, it will still charge them, but need to keep a check on them, later chargers, monitor the battery voltage, and adjust output to suit. All chargers work the same way, so basically yes, but keep a check on them, not running to hot etc. check voltage if you can. But they all work the same way, just later cells are used to the controlled cct of later chargers. especially with them being so called sealed, they still let gas escape, via a pin hole, If they get hot, to much gas, going out, reduces the effiency of the electrolyte, so will reduce the life, BUT as long as you keep checking them and stop if they get hot no problem, they will get warm anyway.

You need to obtain an "EV Warrior SuperCharger". I just found a few on Ebay for about $80
It is a 5A-24v battery charger with a standard 3 Prong Connector

I can't find any reference to a Homelite model 720 generator but most battery charging systems do not supply enough amps to run a car starter. Battery chargers usually work in the two (trickle) to ten amp range. Car starters need way more amps to have enough power to turn an engine over, depending on the size and number of cylinders in the motor. Some chargers have a switch with a 60 amp 'start' position to help the battery turn the motor over, but without that there is little chance the charger side of your generator will supply enough amps to help your battery.

Are you having this problem on a particular battery? Try using it on your car's battery with the headlights on. The headlights should brighten and the unit show 5 -10 amps charging.
A car battery can develop a problem where the battery post gets disconnected from the inside. This is common on batteries in storage or left on charge a long time or used in a car with a defective alternator. The battery is charged but it won't start a car. headlights connected look normal until you turn the key, then the headlights will just go out. This descibes a bad battery.

No, the battery cannot be charged using the USB cable. You need the supplied battery charger. If you've lost it, you'll have to buy a BC-CSK or BC-CSKA charger from Sony.

I have a PDF of the schematic i drew for my bike. it is posted on the Yahoo power-assist group. look in the files section.

http://tech.groups.yahoo.com/group/power-assist/files/EV-Warrior/

there is also a text file there that lists all of the wiring connectors and where each of the wires goes. as well as connection diagrams for the Curtis 1505 speed controller.

the charger circuit is very simple. the black and red wires from the charger port go straight to the batteries +24V and 0V terminals. the third white wire connects through a bullet connector to pin#7 (EPO wire) of the Curtis speed controller. this acts to turn off the motors while the batteries are being charged.

inside the charger male connector the pin for that 3rd white wire is shorted to ground. so when you plug the charger in the white wire is grounded thru the charger plug.

have fun. i really enjoyed my EV-Warriors while i could still ride them.
