Description
The BIM75040-250K modular energy storage PCS converter is constructed with bidirectional high-frequency isolation ACDC modules, combining the advantages of high-frequency isolation and modularization. The cabinet can accommodate both AIM75040 and AIM300100 modules, and can be flexibly configured into different power levels and battery voltages according to requirements
Product Features:
- Safer and more reliable:
- Full high – frequency isolation design ensures safety between the battery and the grid/load;
- Friendly to the battery, battery packs are connected in parallel, reducing battery series – parallel connection, avoiding battery 环流 (circulating current) problems, and extending battery life;
- Compatible with battery packs of different manufacturers and different characteristics connected to the DC side of the module;
- Friendly to the grid, the AC sides are paralleled together, showing single – unit characteristics.
- More efficient:
- High – frequency isolation between the battery and the grid, eliminating the industrial frequency transformer, with higher high – frequency isolation efficiency, reaching more than 95%.
- More intelligent and friendly:
- Cooperating with the STS module, seamless switching between grid – connected and off – grid can be realized;
- Covers multiple battery voltage levels of passenger cars (40V ~ 750Vdc), with a wide battery voltage range.
- Lower cost:
- Compared with traditional modular energy storage, high – frequency isolation eliminates the industrial frequency transformer and indirect costs (cabinet, fan, etc.), and the system cost is low;
- Through a set of circuits, two functions of charging and inverting are realized, and charging and discharging are integrated, with low cost.
- More flexible configuration:
- Module hot – swap design, flexible system configuration;
- Flexibly configured into energy storage converters of different power levels and battery voltage levels according to requirements.
