Hi Im a new owner of a smart fortwo cabrio 2014. Im living in Norway but bought my car as an imported car from abroad. The Norwegian dealer only sells smart fortwo with the small onboard charger3,7-4,6 kw but I see that some of the abroad cars got an optional onboardcharger with 22 kw. How can...

We used to install plug-in upgrades to Prii, and we now have many broken Elcon chargers for repair that we do not need. Once you get them to work, they can be reprogrammed to fit your charge curve (see Elcon's website). We're looking to sell them for $20/charger plus the cost of shipping. We...

Hi everyone, I see a strong interest in off-the-shelf on-board charging module among the electric vehicle enthusiasts. Me and my friend, firmware and electrical engineers, who worked over 10years for the leading EV companies, realized that maybe we can design one and bring it to you guys. The...

Precharge of the capacitors on a drive inverter is well understood - and most inverters manage this themselves. But I'm curious about the other accessories that run on ~380 volts DC. DC/DC converters have a certain amount of capacitance that would potentially weld a contactor. Likewise, high...

Good Evening All, I'm finally at a point where I can stop lurking and ask a question. I'm finally ready to upgrade my LiFePo4 charging / balancing set up and was hoping to get some insight from anyone who knows a little about the FMA CellPower PowerLab line. I'm set on getting a PowerLab 8 so...

Our eDub Electric VW camper van, has an on board 8kW 144V TC Charger (non-CAN) and on Monday, it stopped working.... :( When connecting to power, the cooling fans kick in but it doesn't draw any power to the batteries and the status LEDs don't turn on, not even for an error message. I wonder...

While working on my prototype for a flying capacitor BMS with charging capability for the bottom cell using the entire (4 cell) pack, I got to thinking that, instead of charging that one cell and using traditional shunt current balancing, why not design a charger for a single LiFePO4 or LiPo (or...

Hey Guys, I'm new to the forum. I'm building a battery pack for my EV, i need a 48V 100Ah pack which can discharge at 3C. I plan on using NMC batteries for the same. I plan on making 5 packs of 48V 20 Ah each and then connecting them in parallel(yes, i know 13s NMCs will give me 46.8v but...

Hi all, I need some help from the community, we are looking for someone who has stuck an oscilloscope onto the charger during the charging phase and knows the tolerance that Tesla uses for the Voltage and current ripple on its chargers? We know that the SAE and CHAdeMO standard is usually...

Hi everyone, I recently purchased a 444cell Tesla Battery Module (~5KWhr). Might anyone recommend which charger to get (that plugs into US 120VAC wall socket)? If you have experience in charging these battery modules, what's the time it'll take to charge the battery given the amp output from...

I need badly to see more charts and graphs and equations to help me understand the relationships between all these units of measurement I hear related to ev conversions. We need like a master chart for every known usable component on the market or in a salvage yard. starting with battery...

Hi everyone, I've been fantasising for some time about the possibility to convert a diesel powered boat into a series hybrid, using a diesel generator and a LiFePo battery pack connected to an electric car motor. It would be a semi stationary live-aboard, so run time requirements are pretty...

i am no longer selling

hi, I have a complete conversion for sale, currently in a Porsche 911, would prefer to sell a set, but may part it out - please let me know what you need. I can sell the batteries/chargers/BMS first as they could go into any car. Here is some more info on ebay auction...

This is now SOLD

Hi, I've owned a Twizy for about a year now and I love it, the main thing I don't love is the time it takes to charge such a small vehicle. Is it possible to replace the charger and connector to allow for rapid charging maybe on either a 16A or even 32A Type 2 charger? Any help would be...

For sale: Eltek 220/300 Charger Like new, was used to charge the battery pack of an experimental EV conversion 2-3 times. The battery pack layout of redesigned to use a different voltage and as result this charger is no longer need. Charger is almost new and in excellent condition. Please...

I have finally gotten started on my efforts to work on a couple of these chargers that forum members have had trouble with, and sent to me to see what I might be able to do. I am still recuperating from cervical spine surgery so my mobility is a bit limited, but I have made some progress, and I...
