A bidirectional current (BidC) [1] is one which both charges and discharges at once. It is a current that flows primarily in one direction and then in the other. [2] Complicated systems which have integrated recharging capability sometimes resort to using bidirectional currents, as in Laptops or other systems. Monitoring of a bidirectional current is required for a laptop to report the battery level and charging status.[3] Components are available for this purpose.[4]
