Abstract: The present invention provides an actively rapid battery voltage balancing system which includes a power converter, a switch, a voltage balancing multiplexer, a voltage measurement multiplexer, a voltage sensor, a microprocessor, and a series connected battery pack. By the application of the above components, the balancing voltage conditions of each battery cell in a series connected battery pack can be actively monitored and estimated. While in the charge or discharge period, if a battery cell in the series connected battery pack is determined to be an unbalanced cell, the voltage balancing process can be carried out promptly. Less component is required to fulfill the purpose of the cell voltage balance in the present invention.

Abstract: The present invention provides a system and device for current measuring, controlling, and heat sinking which includes a positive electrode terminal carrier, a positive electrode output terminal carrier, a negative electrode terminal carrier, and a current control circuit carrier. The system and device is to be installed on a battery with high current capacity. In which the output current flowing through the battery's positive electrode is measured by the current measurement device which is installed in the positive electrode terminal carrier. A reverse current control switch and a forward current control switch are installed in the current control circuit carrier to control the current flowing path and the current flowing in the path. Furthermore the heat generated by the circuit is radiated by the current control circuit carrier.

Abstract: A smart lead-acid battery charging/discharging management system comprised of one or a plurality of identical smart battery unit with each including a controller, a lead-acid battery, and a sensor switch device working together with a alternator and a voltage regulator to upgrade charging efficiency, achieve consistent capacity among batteries, and isolate malfunctioning or failing battery to extend service life of the battery.

Abstract: The high reliable smart parallel energy storage tank charge/discharge system is composed of one or multiple identical Smart Energy Storage Unit. And each Smart Energy Storage Unit comprises an Energy Storage Management Module, an Energy Storage Device, a Sensor Switch Device and a Smart Identifier and Transmission Interface. All the historical records and real time information for charge/discharge condition of Smart Energy Storage Unit can upload to external connected equipment via the External Equipment Interface. To operate in coordination with an External Energy (Electric Power) Source, under any one Smart Energy Storage Unit served as the controller, this management system can carry out an effective charge/discharge management.
