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.

Rated output voltage: 24 / 48 / 80 / 120 / 220 / 400 V
Output current range: depending on the selected type and configuration
Efficiency: up to 94 %, PF cos φ ≈ 1
Technology: high-frequency, active PFC, galvanic isolation between input and output
Operating modes: standard charging, opportunity charging, regenerative modes
Operating conditions: −10 °C to +40 °C
Protection rating: IP20 (IP54 on request)

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
