GlennWest Posted April 17, 2020 Report Share Posted April 17, 2020 With my Leaf battery pak I would like the option to charge with any circuit, 15amp, 30 amp, 50 amp. Thinking a seperate charger would work. Thoughts?

sushidog Posted April 17, 2020 Report Share Posted April 17, 2020 (edited) Have you decided not to use an inverter charger, or is it so big it will only work on a 30+ amp hook-up? Most inverter chargers have adjustable charge rates, so if you choose one that has say a 60 amp max charge rate at 48v (that needs 30 amps input at 120v) you can just turn it down to charge at 30 amps if all you have is 15 amps DC available. Most can be adjusted from 20-100% of their rated capacity. Chip Edited April 17, 2020 by sushidog Quote Link to comment Share on other sites More sharing options...
GlennWest Posted April 18, 2020 Author Report Share Posted April 18, 2020 I will be wiring the shore power directly into the inverters. This way the Magnum MS4448PAE will only charge battery and supply power to our Teton. I will have cleaner power this way. I will start with two units. I was consideriing a seperate chager for the battery pak if all goes south. It likely not will happen but shouldn't be an exspensive back up.

oldjohnt Posted April 18, 2020 Report Share Posted April 18, 2020 Glenn, to your comment " I was consideriing a seperate chager for the battery pak if all goes south." In the event you want an auxiliary back up separate charger, as I'm sure you're already aware, it has to: Charge at the correct voltage, current, staging and parameters to match your Leaf's battery requirements. I guess that would be the same as what the car used when plugged to shore power for normal charging, can you get one (or how many are required) of those OEM chargers to match your battery ?? How about using solar to charge the batteries if there's no shore power or the Magnum went south ?? Would that not be enough ?? As far as your wanting to use 15 or 30 or 50 amp, subject to the charging requirements, a 15 amp may or may not do the job, I don't have the specs on your battery or what a separate charger requires, but 15 amps sounds on the light side ??? Also obviously, is 120 or 240 VAC required?? If 240, then you need a 50 amp RV type of receptacle......…. Remember I want to park next to you and plug into your system, I'm sure you have enough for BOTH of us lol Take care and best wishes Glenn John T Quote Link to comment Share on other sites More sharing options...
GlennWest Posted April 18, 2020 Author Report Share Posted April 18, 2020 The oem EV chargers voltage is too high.Actually I could put my batteries in operation if I had a charger. My daughter needed a large sum of money for a house downpayment and I had to dish it out. She is my only child and daddy can't say no. So my funds for my projects is on hold. And with the virus lockdown my income on hold. Now I'm not hurting for funds just my projects. But I have the dc/dc wired and in place just not connected. If I had a charger could put this in operation and get rid of lead acid. Plus I'm bored and need something to do.

jcussen Posted May 1, 2020 Report Share Posted May 1, 2020 Glen. I have been looking as well, trouble is the 14s 48 volt packs charge best at 56-57 volts, hard to find in a stand alone charger that will do that. Let me know if you find one. As John T mentioned, solar is the best way to top them off. Quote Foretravel 40ft tag 500hp Cummins ISM 1455 watts on the roof, 600 a/h's lithium in the basement.

GlennWest Posted June 12, 2020 Author Report Share Posted June 12, 2020 Texted Ralph and he can get me a 30 amp charger for my batteries. It is regulated so I can leave it hooked up. I have also been commuting with Steve Dixion. He uses a 2000w dc power supply feeding a PT-100 controller. A quality DC power supply is $500.00. He uses a 4PDT relay in line for switching to power supply. I am thinking just a seperate plug for 30 amp and charger.

GlennWest Posted June 12, 2020 Author Report Share Posted June 12, 2020 Think I going to get 2 of his stocking chargers. That would give me same for $100 less.

In my case, have 5200 watts of solar, if somehow that fails [I am running two strings on 2 solar controllers] I can use the Magnum to recharge the batteries, and if it fails, can use my 15 amp charger on my small generator.

Sehc Posted June 12, 2020 Report Share Posted June 12, 2020 I'm learning about lithium battery. I hear much good about Sterling marine grade chargers. I know they have 48 volt stuff.

Steve Dixon uses this on his nice unit. He also has a 4PDT relay in his 50 amp supply to redirect to dc power supply. Nice power supply $500.00. Could just put a 30 amp next to 50 amp receptacle. Volteq makes great power supplies.
