Laminated Cell Module
- High capacity / high power cells are arranged in series (4 cells / 8 cells / 12 cells)
- Correspondence up to 500 V with series connection of up to 12 units
- Correspond to large current by multiple parallel connections
- Charging and discharging by large current is possible (Maximum charging / discharging current 500 A or more)
- High reliability, high durability, high safety
- Automatic cell voltage equalization function (between cells in a module, between modules)
- No external control power source required
- Low power consumption 20 μA or less (standby)
