Title: ACCUMULATOR BATTERY MANAGEMENT SYSTEM
Abstract:
The invention relates to electrical engineering and can be used in chargers of lithium-ion batteries. The system contains a common control block and control blocks of each of the multitude of battery cells, where each cell of the multitude of cells is controlled by its own control block, which contains a micro-controller that has the capabilities to receive data about the condition of the cell, transfer the received information to the block of common control, and balance voltages of cells by high currents (upon receiving a control command from the common control block), where the balancing mode efficiently operates in any mode of the battery operation (during charging, during discharging, and at rest), where the multitude of cells of the accumulator batter are connected in series by direct current, and in parallel by alternating current through the system of DC/AC converter balancing, where the converters are synchronized by the common control signal from the common control block. The invention reduces the charging time and increases the discharging time of the battery.
