FAQ

Why is collaborating with NOVUM worthwhile?

You can significantly improve the efficiency of your power storage systems with NOVUM technologies, regardless of whether you require longer service life, better utilization of performance or reduction of safety buffers. NOVUM supports you across all phases, from planning to system integration and thus ensures that you get the added value of our technology quickly and cost-effectively.

Are NOVUM products complex to install and commission?

NOVUM sets great store on easy installation and commissioning. Regardless of whether you are retrofitting our products or using them in a new development, the different packages allow immediate use without long training phases or adjustments. This means that you can use both our hardware and software products to add value without delay.

Who performs the installation and commissioning?

Our hardware products are usually installed and commissioned by trained NOVUM personnel. Our laboratory measuring instrument EIS-LAB can be put into operation directly by the user. We will be happy to coordinate the commissioning of our software products with your IT department.

How fail-safe are NOVUM products?

NOVUM’s hardware is subject to strict quality control and undergoes a three-step test procedure. Online control algorithms and regular updates ensure that our software operates very securely. Thanks to an integrated fallback solution, the systems remain functional even in the event of internet outages.

How long is the warranty period for NOVUM hardware products?

The statutory warranty period is two years. By booking a service package, you can extend the guarantee beyond this period.

Is data protection ensured despite the fact that the measured values are transmitted to NOVUM?

Of course, all data is transmitted in state-of-the-art encrypted form and also stored in encrypted form. We host our servers exclusively in Germany and can therefore guarantee the highest level of data protection according to the GDPR and information security according to ISO 27001.

Is NOVUM retrofittable?

Yes. Pure software solution and hardware upgrades are both possible depending on the aim and the selected package. In the case of a hardware upgrade, direct contact with the batteries must be possible.

What is the advantage of impedance spectrum based state of charge detection (SoC detection)?

When determining the state of charge, NOVUM not only takes into account existing current, voltage and temperature values, but can also use information from the impedance spectrum. This means that, on the one hand, the SoC detection can be corrected for the distorting influence of the SoH and, on the other, a precise state of charge detection is possible even when the battery is not at rest. Thanks to the impedance spectrum, the variance in voltage drop can be taken into account in this case.

What is the advantage of impedance spectrum based state of health detection (SoH detection)?

In contrast to other approaches, NOVUM can detect the health condition on the basis of situational measurements. There is no accumulation of measurement errors, as can be the case with Coulomb counting, for example, and it is also not necessary to run regular, standardized reference cycles with NOVUM.

The impedance spectrum also makes it possible to include other forms of aging in the SoH calculation in addition to cyclic aging. As a result, factors affecting performance, which only become detectable later in a capacity reduction, also become visible, increasing the informative value of NOVUM forecasts.

What is the advantage of impedance-spectrum-based temperature detection?

Temperature sensors can only measure the outside temperature of batteries.

NOVUM, on the other hand, determines the internal temperature of the battery via the impedance spectrum and thus knows earlier than the external sensor whether there is a danger of overheating.

This ensures a fast reaction time.

Can NOVUM also work without measurement hardware?

Yes. NOVUM pools comprehensive expertise in the field of artificial intelligence. If sufficient battery data is available, a purely AI-based battery monitoring can be set up on the basis of this. This requires high data quality and an online connection to the NOVUM IT systems.

How does battery-preserving charging and discharging management work?

NOVUM knows the state of health of the batteries and, thanks to the impedance spectrum, other factors relevant to ageing. Charging and discharging current are now adapted to the battery condition to minimize wear and tear. The avoidance of excessive heating is also part of this. By quickly determining the internal battery temperature, NOVUM has a clear advantage over temperature sensors.

We already cool our batteries, doesn’t this make battery-preserving charging and discharging management superfluous?

As the battery wear increases, the battery heats up more and more during use until the point where battery wear accelerates and the battery finally becomes useless. A cooling system ensures that this tipping point is postponed. Thanks to appropriate charge and discharge management, NOVUM has a complementary effect in this regard and significantly slows down the rate of battery wear not only before but also after reaching the tipping point.

Why can NOVUM charge faster without increasing the efficiency of the charging electronics?

NOVUM uses the information about the battery chemistry and the internal battery temperature obtained from the impedance measurement to work with a dynamic instead of a static final charge voltage. This means that the CC charging phase can be used to its full potential and the slow CV phase is in many cases no longer necessary to fully charge a battery to 100%.

For which battery types is NOVUM battery monitoring suitable?

NOVUM technology is suitable for all types of battery chemistry.

How does the training work?

NOVUM works with a combined analytical and empirical approach. Information about the respective battery chemistry from our model library is combined with field data. If no field data of sufficient quality exists, we create it in the laboratory by setting up a state space.

Does the NOVUM battery status detection also work without a cloud connection?

Yes. With small reductions in accuracy, a simplified form of battery condition detection also works without a cloud connection. For some use cases, however, a cloud connection is mandatory due to the required computing power.

Is there a way to simply try NOVUM technology?

Yes. NOVUM offers the EIS-LAB laboratory measuring device. This not only allows impedance spectra of own batteries to be recorded: online registration also enables a state of health detection (SoH) to be performed on the supplied battery types.

How does NOVUM evaluate the impedance spectra?

As we know from science, evaluating impedance spectra is not a trivial matter. Contrary to the usual laboratory environment, NOVUM does not work with equivalent circuit diagrams, as these are usually too complex to be effective under practical conditions. Instead, in a first analytical step, NOVUM identifies characteristic anchor points in the spectrum and combines this with a black-box approach based on neural networks. With the aid of transfer learning, we can also apply knowledge acquired from our model library to other batteries.
