  In the existing series high-voltage residential energy storage system, the cost of battery cells takes a high proportion, the production impedance distribution cost is high, and the initial investment cost is high

  The small-capacity battery cells of the series high-voltage residential energy storage systems on the market are expensive, with high homogenization, and PACK cost accounts for a high proportion of the total system cost. Also, it requires high consistency of battery packs, leading to high production end impedance distribution cost, long cycle, and higher initial investment pressure for enterprises.

  The residential energy storage series high-voltage battery modules require high battery consistency, causing high system operation and maintenance costs

  The series high-voltage system requires high consistency of battery packs, which results in high impedance distribution costs and long cycles for transportation/stor- age/on-site replacement due to faults and brings huge operation and maintenance costs to the enterprises.

  Barrel effect in residential energy storage system PACK

  In case of malfunction of a group of PACKs in a series high-voltage system, it will cause the entire system to shut down; In case of a demand for expansion in parallel high-voltage systems, if new and old batteries with significant differences are directly used in parallel, it will generate high uneven current between the batteries, and further speed up battery aging with the increase of charging and discharging times.

• 

  Adapt to 314Ah large-capacity battery cells to reduce PACK costs; System configuration on demand, saving redundant battery configuration; High-voltage parallel battery modules solve the problem of high material and labor costs due to impedance distribution during the production of series battery boost modules.

  Low initial investment cost
• 

  Reduce the production end impedance distribution cost and cycle, solve the problem of high impedance distribution cost and long cycle for transporta- tion/storage/on-site replacement due to faults, and reduce the customers’ operation and maintenance costs.
