Charging technology
We develop chargers for DC and AC power supplies and an output voltage range from 12V DC to 1000V DC.
Precise current limitation
To meet demanding requirements, the input and output current of chargers can be limited by configuration.
Diagnostics via CAN/ETH
Various measurement and control parameters can be used for diagnostic or control functions via a standard CAN or Ethernet interface.
External sensors
An additional interface enables the use of external sensors. For example, the voltage can be measured directly at the battery terminals, and thus the output parameters of the charger can be adapted to the needs of the battery.
Impedance measurement
The chargers are capable of measuring the impedance of the connected peripherals both primarily and secondarily. This allows defective cables or incorrectly plugged connections to be detected at an early stage.
Fields of application
Onboard charging technology
Onboard charging technology
In order to be able to charge battery electric vehicles at standard household sockets, an on-board charger is required, which transforms the single- or three-phase alternating voltage into the direct voltage required for the battery.
Industrial UPS systems
Industrial UPS systems
In order to guarantee an economically reasonable and redundant protection of the energy supply of industrial applications and data centers, "uninterruptible power supplies" so-called UPS systems are used. They consist of a rechargeable battery which safely supplies critical systems in case of load peaks or power failures. These UPS systems must be charged around the clock to conserve the battery, for which Querom charging technology is ideally suited.
Mobile electrical applications
Mobile electrical applications
Due to the increasing performance of Li-Ion rechargeable batteries, more and more devices that were previously powered by batteries are now being operated with batteries. In the past, they were primarily cordless screwdrivers, but today they are also used in lawn mowers, chain saws and much more. Different chargers are required for safe and reliable operation of the devices.
