A Cell-to-Cell Equalizer Based on Three-Resonant-State Switched-Capacitor Converters for Series-Connected Battery Strings
Abstract: Due to the low cost, small size, and ease of control, the switched-capacitor (SC) battery equalizers are promising among active balancing methods. However, it is difficult to achieve the full cell equalization for the SC equalizers due to the inevitable voltage drops across Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) switches. Moreover, when the voltage gap among cells ...
متن کاملSingle Switched Capacitor Battery Balancing System Enhancements
Battery management systems (BMS) are a key element in electric vehicle energy storage systems. The BMS performs several functions concerning to the battery system, its key task being balancing the battery cells. Battery cell unbalancing hampers electric vehicles’ performance, with differing individual cell voltages decreasing the battery pack capacity and cell lifetime, leading to the eventual ...
متن کاملAnalyzing a Resonant Switched- Capacitor Converter for Improving Lithium-Ion Battery Cells Balancing Speed
Active techniques based on the switchedcapacitor converters (SCCs) are used in recent years widely for battery cell balancing applications, due to lack of bulky magnetic components. In addition, these converters are easily be integrated to reduce the volume. Despite of all these benefits, SCCs have some disadvantages such as number of active switches, currents spikes, low balancing speed, and h...
متن کاملPhase Angle Control in a Series Rlc Circuit Using an Electronically Switched Capacitor
In this article the principle of the switched capacitor in a series RLC circuit is presented. The classical methods for phase angle control are described, and a novel control method, where the capacitor is placed in the centre of a bidirectional H bridge switches. Using an electronic circuit simulation program, the representative voltage and current curves are obtained. The phase angle at vario...
متن کاملan Efficient Drive Circuit for Switched Reluctance Motor
The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...
