Amnon's EV-30x

Ev-30x has been run on the lead acid batteries but they only provided a few km's range due to their poor condition. The car accelerated reasonably well for the amount of weight, and i have only had it running up to 60km/h so far. The project has been on the backburner for a while, but now needs to b...

Flooded lead acid question

i got some quotes for the green-saver batteries. Prices were very reasonable ! I ended up getting 12 Ex UPS 75Ah AGMs(25kg each) for $35 each just to get my ev up and running. Who knows, they may even last a year or so. There will be 6 AGMs in the engine bay and 6 in a box where the back seats would...

Hi Ron, Does the Sherpa weigh 850 with 360kg worth of batteries? That must be a truly light car. Im starting with a car that weighs 900kg with engine out and no batteries.

High power Lithium Charger

I recently got a 2.2kW cont. 4 stroke gen for a good deal(not inverter type). The next step is working out how to get about ~160Vdc for charging a 144VDC battery system. For a budget charging system could i just get a rectifier and transformer. Would smoothing capacitors be required or can batteries...

You dont want to go from GCI back to DC again. round trip could be as bad as 75-80% eff. The inverter needs to be sized at the PVpeak capacity rating. If voltage is hi...

Grid Connect PV systems

excuse my ignorance, but why would the voltage rise? Most GC inverters output 230V +-10V.
Ive seen inverters in my local area where the external grid voltage was 250V which caused the inverter to shutdown(overvoltage safety).

High power chargers tend to be very expensive. Im just thinking ahead here, I want to build a 144V high power charger for lithium thunder-sky batteries when i get them.
