Universal Battery Active Equalizer Balancer Lithium Battery Balance Board 12‑16S Active Equalizer Module Lightweight Energy Transfer Board for LTO LPO LFP 1.8V‑4.5V

Product Information

Since the inductance is constant, it can be observed that the peak value I pk of the inductor current is proportional to the battery voltage V B 1. Z. Low cost battery equalizer using buck-boost and series LC converter with synchronous phase-shift control. Therefore, a single voltage loop equalization control strategy can be obtained, as shown in Figure 5. Furthermore, the sum of the conduction time and the cut-off time is the time of the switching period, then Equations (8) and (9) can be derived, respectively.

The energy consumption equalizer adopts a resistor and switch tube in series and then in parallel with the cell. A Method to Identify Lithium Battery Parameters and Estimate SOC Based on Different Temperatures and Driving Conditions.To verify the effectiveness of the phase shift control strategy an experimental prototype of a half-bridge Lithium-ion-battery equalizer is established, and the experimental results prove the effectiveness of the proposed method.

Since a converter-based equalizer uses magnetic components such as transformers or inductances as energy storage components to transfer energy, it can be designed to transfer energy from a cell to a module or from a module to a cell.In S ij(S 11) and B ij, i represents the switch tube and cell in the i-th half-bridge topology, and j represents the j-th switch tube or cell in the i-th half-bridge topology.
