Abstract
A current limiter placed in the charge path of a battery limits the charge rate that a battery charger can provide to the battery. The battery temperature, voltage, and current are monitored to determine whether the battery can handle a faster rate of charge than the current limiter allows. If the battery can handle a higher rate of charge, a transistor configured in parallel with the current limiter is enabled which by-passes the current limiter and allows the battery charger to charge the battery at a higher rate.
