FLEXIS
High-frequency industrial traction battery charger
FLEXIS is a multifunctional, modular and programmable high-frequency charger for traction batteries designed for demanding industrial operations. It is engineered for long-term, multi-shift and continuous operation, where reliability, high efficiency and maximum equipment availability are essential.
Thanks to its wide compatibility, intelligent charging management and support for intermediate charging (opportunity charging), FLEXIS represents a modern solution for logistics, warehouses and industrial production.
Use and applications
The FLEXIS charger is primarily intended for charging traction batteries used in:
- forklift trucks
- material handling equipment
- work platforms
- industrial and logistics vehicles
Supported battery types:
- lead-acid batteries with liquid electrolyte
- AGM and GEL batteries
- lithium-ion batteries (Li-ion)
- alkaline batteries (NiCd) and others
Thanks to this versatility, a single FLEXIS charger can be used for multiple different batteries within one operation.
Main benefits
- High efficiency up to 94 % → lower energy consumption and operating costs
- Opportunity charging support → charging during short breaks without negative impact on the battery
- Modular design → easy power scalability and fast service
- Extended battery lifetime thanks to intelligent charging control
- Intuitive operation and a clear color display
- Designed and manufactured in the Czech Republic
