Everything depends on the details, Lawrence. What kind of EV? What type of battery, and what is its pack voltage? What is the PV array's voltage and peak power?
If he's dealing with a commercial EV like a Tesla, it's going to be expensive and complicated (as others have pointed out). He's better off using an inverter to turn his DC into a standard AC voltage that the EV's charger already knows how to use. But if it's a homebuilt EV conversion, it might be a lot easier, especially if he's not talking about truely "fast" high-power charging. For decades, I had a 30v 4amp peak PV array on my garage roof. I had a couple simple charge controllers, and used it to charge all my small EVs (Ebikes, lawn mowers, and garden tractors). I also used it to charge the batteries in my Lectric Leopard (LeCar EV conversion), 24v worth of batteries at a time. Most of these were lead-acids, which are pretty simple to charge. For the nimh and lithium batteries in my Ebikes, I used an MRC Super-Brain 989, which can be set to properly charge all types of batteries.
