    solar charger for electric vehicles

    hello,
    i am into a project of designing a solar charger for electric vehicles. the electric vehicles have a battery operating at 59V and of 20Ah. can anyone please guide me as to what solar panels must be used and other required details.

    First - will the vehicles be parked and plugged in to charge during the sunny part of the day ?

        OK, so the vehicle is parked all day under the panels for recharge.

        What amount of power is used at night & what is the KWh capacity of the battery bank in the vehicle?

          Yes it is designed for application as u go to work and vehicle is just idle at your work place. Then why not use that idle time to charge the battery using solar

          The capacity is 20Ah.kWh specifications are not specified. Also the battery is of 59V as I specified

            Just what kind of vehicle uses a 59 volt 20 AH battery? A golf cart has 20 times that capacity.

              20KAH maybe??

              Any way most of the systems I have seen like this are basically just grid tied system anyway. pretty simple do to that way and you get benefit of electricity when no car being charged during the day as well as night charging capabilities.

                It would be extremely foolish and poor design using a 59 volt 20,000 AH battery. No one in their right mind and who knows anything about motors and batteries would never ever do that. EV's use higher voltages of 300 to 600 volts and th elargest I know of is Tesla S Car with a 60 Kwh battery that operates at 400 volts 150 AH battery. Nissan Leaf uses a 400 volt 100 AH battery.

                A 59 volt 20,000 AH battery would weigh in around 1.18 Mwh and 65,000 pounds. No way Jose.

                  I think the 59v (60v) 20ah battery is used on a small two or 3 wheel bike or scooter from Asia.

                  Too small to run any type of 4 wheel vehicle.

                    He is probably talking about the auto rickshaw. Only thing is that those guys are constantly on the move
