ULTIMO® High Voltage Module

Up to 48 cells with high capacity and high output are arranged in series
With up to 8 series connection, up to 1000 V can be supported
Multiple parallel connections allow for large currents
Rapid charge / discharge with large current is possible, maximum instantaneous charge / discharge current 500 A or more
Equipped with a terminal safety mechanism that does not output voltage to terminals to prevent electric shock
Equipped with FUSE in main module, failure avoidance by abnormal charge / discharge
Two types of standard type / air cooling type, air cooling type can be attached to external fan
Acquire detailed information such as cell voltage and temperature by CAN communication
High reliability, high durability, high safety
Automatic cell voltage equalization function (between all the cells in the serial module row)
