Copper Busbar For Energy Storage System

1.Energy Storage System: (Internal connection (core transmission layer) of battery pack / module)

✱ Application scenario: Series and parallel connection of lithium battery modules, current collection of battery cells, auxiliary connection for signal transmission of battery management system (BMS).

✱ Copper busbar type: Precisely customized bus (mainly hard copper bus, suitable for narrow spaces with soft copper bus), tin-plated / silver-plated copper bus.

✱ Core function: Achieve high-current and low-loss transmission between battery cells, ensure voltage balance of modules, and reduce local overheating.

2.Energy storage distribution box (central distribution layer)

✱ Application scenario: Current collection and distribution of multiple battery packs, connection of battery clusters with PCS (Energy Storage Converter).

✱ Copper busbar type: Large cross-section current collection copper bars (cross-section 500 - 2000 mm²), insulated copper bars (spray painting / heat shrink tubing).

✱ Core function: Centralized integration of multi-module currents, reduction of bus impedance, and realization of stable current distribution to the converter.

3.PCS Energy Storage Converter (Energy Conversion Layer)

✱ Application scenarios: Connect the combiner box to the power grid to achieve current transmission during the DC/AC conversion process.

✱ Copper busbar types: High-frequency low-impedance copper bars, silver-plated copper bars, water-cooled copper bars (for high-power scenarios).

✱ Core function: Adapt to the high-frequency switching characteristics of the converter, reduce electromagnetic interference, and ensure energy conversion efficiency.

4.Energy storage container / Control cabinet (System integration layer)

✱ Application scenarios: Main busbars inside containers, grounding connections within control cabinets, power supply connections for auxiliary equipment.

✱ Copper busbar types: Grounding copper bars, bare copper bars, bent-formed copper bars.

✱ Core function: Construct the grounding protection circuit of the system to ensure the safety of equipment and personnel; achieve stable power supply for auxiliary equipment (fans, monitoring devices).
