Enerkey 2a Lifepo4 Balancer 2s-16s Lifepo4/Li-ion Battery Energy Transfer Equalization
The active balancing of BMS can only play a limited role. At present, more and more energy storage systems adopt a one-cluster-one-management design, and the consistency of the battery cells is getting better and better.
From the perspective of the operating effect, if active balancing or equalizers are added, it is easy to increase the failure rate. Through the one-cluster-one-management design,
the battery cells of third- and fourth-tier manufacturers can achieve the effect of the top battery cells. Due to the relatively lower price, most of the domestic source-grid side energy storage systems are centralized architectures.
Industry insiders said that large storage systems with centralized architectures also need to solve the problem of balancing between clusters, and the requirements for balancing capabilities are higher than those of string-type systems.
In order to cope with the problem that the passive balancing effect of BMS is insufficient and active balancing is prone to cause failures, more and more energy storage companies are developing their own balancing technology.
However, configuring BMS active balancing or adding DC/DC modules also means higher costs.
Enerkey learned from an interview that the 6.25MWh long-term energy storage system solution launched by Enerkey can add external active balancing equipment when the battery fails in the later stage.
Enerkey's self-developed active balancing device is also used for balancing between batteries, but it is different from conventional BMS active balancing products and is not a conventional DC/DC module. In comparison, it has higher stability and relatively moderate cost.
