Model G6S - Measuring Module for Cell Voltage Monitoring (CVM)
The G6S CVM solution was specially developed for cell voltage monitoring in series applications. It is scalable, allowing both single cell measurements and voltage measurements across two or four cells. The measurement modules are supplemented by a target market-specific head module, which is equipped with the data interfaces prevalent in the respective target market. The head module also offers additional functions, such as measuring the total stack voltage to check the plausibility of the individual values.
In addition to automotive, SMART TESTSOLUTIONS addresses the marine, aviation and electrolysis markets with the G6S. By using the same measurement modules in all application areas, economies of scale are achieved in production. Compared to the predecessor version G5S, the costs per measuring channel are up to 75 percent lower with the G6S.
The provision of the Profinet Ethernet standard for industrial applications via the correspondingly adapted head module should be of particular interest for use in electrolysers. It enables a direct connection to the process bus system of the electrolyser control systems.
The CVM G6S module was specially developed for cell voltage monitoring in series applications.
Areas of application in detail:
- Marine
- PASSENGER CARS / COMMERCIAL VEHICLES
- Avionics
- Rail vehicles
- Electrolysis
A CVM G6S measuring module has 54 measuring channels. Several modules can be cascaded. A system consists of several measuring modules and a target market-specific head module.
- Cascadable modules
- DC measuring range suitable for single-cell, double-cell or quadruple-cell scanning
- Interference resistance due to internal oversampling and filtering
- Insulation resistance 1.4 kVDC
- Time-synchronous acquisition of all cell voltages
- Operating temperature range -40 ... +105 °C
- Common toolchain with CVM G5 and CVM G5S
- Customized adaptations on request
Our CVM systems for use in cars and trucks are approved for series production in accordance with automotive standards. These include LV 124 and DIN EN 60068, and an EMC test is also carried out in accordance with CISPR 25.
Leading marine and naval equipment suppliers have relied on our CVM systems for years, with new ones are being added all the time. Our systems for use in ships and submarines are tested to MIL standards.
In electrolysers, our CVM systems contribute to system safety by monitoring the voltage in the cells. An explosion-protection version with ATEX certification is available on request.
Fuel cell drives are also increasingly being developed and tested in aviation. Since passenger safety is the top priority when flying, the most exacting standards have to be met.
For rail vehicles, we also offer customised systems that meet the relevant industry standards. Our CVM systems provide valuable information for the operation of the drives and thus enable the longest possible service life.
