摘要： A system and method dynamically equalizes battery voltages with low inherent power losses in a string of series connected electrochemical batteries. The method includes charging/discharging a group of batteries using magnetic storage in a transformer with bipolar magnetic excursion, individually isolated circuits and pulsed energy transfer. A method also exchanges current between batteries using direct current transfer between them and limiting inductance. Using this method, battery voltage may be measured from an isolated circuit, thus enabling information transfer to a central monitoring system. The method also has the benefit of providing an estimation of battery internal resistance from isolated circuits in the series of batteries.

摘要： A dynamic braking circuit that can be operated with stability over both high and low speed regimes. This circuit has the advantage of using fewer components than previous circuits. In addition, when in braking mode, the armature and field currents tend to oppose each other across the main braking switch hence reducing electromechanical stresses when in high current regime. According to a second embodiment, a dynamic braking circuit implements a “soft” extended braking function with the capability of providing a smoother braking action at high braking effort at little extra cost resulting from the replacement of a contactor by a reverser. The main advantages of this preferred embodiment are that the current generated by the armatures during braking can be controlled independently from the excitation of the field windings at low speeds and that it enables simultaneous self supply, regeneration and dynamic braking.
