Production process

  • Device
  • Analysis of electrical requirements
  • Selection of power supply parameters
  • Optimum and safe operation of the battery system

Determining the parameters of the power supply system based on the specifications of the particular device.

  • Selecting optimum parameters of the battery systems, e.g.:

– mechanical parameters, which ensure suitable strength considering the available space and operating conditions of the device;

– electrical parameters, which ensure uninterrupted, correct and safe operation of the device;

– electronic parameters, which enable monitoring of operating parameters, system safety and communication with the device;

– thermal parameters, determined in accordance with the range of temperature and environmental operating conditions of the device;

– durability, which ensures the longest possible life under particular operating conditions.termicznych.

  • Ensuring product safety.

    the final application
  • Laboratory tests
  • Dedicated power source
  • Analysis of assumptions, technical parameters, functionality and efficiency at every design stage.
  • Tests using the final application.
  • In-house laboratory tests – detailed assessment of materials, methods and technologies used in the pack. Laboratory tests are also contracted to certified bodies – including a close cooperation with the UL International Poland Sp. z o.o. laboratory, Institute of Non-Ferrous Metals / Central Laboratory of Batteries and Cells.

Technologies of power sources

The R&D Department develops power supply system solutions using the three primary technologies: lithium-ion (Li-Ion), occasionally nickel-metal hydride (Ni-MH) and, sporadically, non-rechargeable (primary) lithium and alkaline technology.

  • Lithium-ion: cutting-edge, commonly applied cell technology with the largest available energy density. Lightweight, efficient power source for many applications, from popular equipment (e.g. phone or computer) through professional electric power hand tools to large energy storage systems for electric vehicles or industrial applications.
  • Nickel technologies: stable and safe power sources. Used by consumers and extensively utilised in medical equipment and industrial applications (metering, emergency lighting) and in cutting-edge solutions, e.g. energy storage in hybrid vehicles.

Integrated electronic systems

  • Advanced products using the Li-Ion technology are always equipped with a multistage electronic operation monitoring system (BMS) to ensure complete safety of the system.
  • The BMS measures all parameters of the cells and, where necessary, disconnects the circuit and conducts cell charge balancing, which significantly increases the efficiency and extends the life of the power source.
  • In order to provide the additional functions, the power supply system communicates with the devices using typical communication protocols (CAN, SPI, SMBus, I2C). The R&D Department designs systems and their components and software in accordance with UN 38,3, IEC 62133, UL 2054, UL 2595, UL 2271, UL 1998, UL 991, ISO 26262, EN 50604 and EN 15194 standards, application requirements and specific requirements characteristic to the particular market to ensure their functional safety.

Mechanical components of the power supply system

  • Battery packs are built to match the power source parameters to the requirements of the application. Frequently, a very important aspect is the space available inside the device as well as the environmental operating conditions of the device.
  • That is why the R&D Department also designs a dedicated cell holder and housings for a specific power supply system. The cell holders and a large part of the housings are usually built as a multi-component plastic injection mould. We also design steel and aluminium housings. The main functions of the housing are to protect the power supply system against vibrations and shocks, remove heat from the cells into the radiator and protect the cells against water and dust.
