Lithium battery cell charging module

Intended use

The lithium cell battery charging module type BCK-60 was made to order by the KOMAG Institute of Mining Technology.The module is designed to charge lithium cell batteries - LiFePO4 cells with BMS supervision system. It has three independent outflows with E = 20 kW. They enable safe charging of three lithium cells with a total energy of 120 kWh in 2 hours. Communication with BMS takes place via the CAN interface.

The charging module was placed in a metal cabinet manufactured by Radiolex company from Pruszcz Gdański, with dimensions of 1830x1550x883 mm and IP67 protection degree. The cabinet has been protected against corrosion and powder coated.
