Average active BMS price range: $500-$2,000. Hybrid BMS – As the name implies, hybrid BMS combines elements of both passive and active systems. This allows optimized functionality per cell at lower costs than purely active BMS. Hybrid systems actively balance while monitoring voltages, while allowing passive shunting on cell voltage thresholds.
The cost of the BMS can account for about 5% to 10% of the total battery storage system cost. For a 2MW system, if we assume a BMS cost ratio of 8%, and the total system cost excluding the BMS is $800,000 (as calculated for the battery cost above), then the cost of the BMS would be $800,000 * 0.08 = $64,000.
With almost full capabilities at partial costs, hybrid BMS presents excellent middle-ground options for many lithium battery applications. Average hybrid BMS price range: $800-$1,500. Capabilities and pricing can vary widely for BMS. Here are 6 of the leading global manufacturers serving both consumer and industrial lithium battery markets:
