Inductive power transfer

    Hi, I am planning to build a wireless charger to charge up car battery.
    I am wondering what to do to the secondary coil in order to have enough energy to charge the battery ..
    thank you.. ^^

    The best thing you can do is minimize the distance between the primary and secondary coils. Is this a trickle charger? Why do you want it to be wireless? Where are you planning on putting the secondary coil on the (metal) car? Will you put the hood up to do the charging?
