Unravelling the smart software in our batteries: how it works and its key benefits

Smart batteries not only store energy, they also optimise energy use, reduce costs and create new sources of income, all while supporting the transition to clean energy. That’s how they earn the title ‘smart’. How does it work? It’s all in the software! In this article, we want to take the mystery out of software, so that you can better understand the various ways in which a business can benefit from an intelligent battery system.

The software that makes our batteries smart

Iwell’s smart batteries consist of integrated hardware and software. The modular hardware design offers scalable power and capacity for efficient energy storage. The software, on the other hand, takes into account a wide range of external and internal factors to manage energy flows as efficiently as possible, based on a company’s needs. In our latest article, you can learn more about how batteries work and their practical applications for businesses. In this article, we’ll dive straight into the three different types of software that run on our batteries: controllers, optimizers and advanced modules.

1. Controllers make sure the basics are right

Controller software services ensure that the battery always has enough energy stored to supply the company with the power it needs, while ensuring that the limits of the energy contract, grid connection, EV chargers and solar panels are not exceeded.

What exactly does the software do?

Ever noticed how power consumption can spike when large machines are running? The Peakshave controller smooths out peaks by letting the battery release extra power when needed. This avoids expensive upgrades of the grid or energy contract. If a company has solar panels, the PV curtailment controller steers the inverter of the solar panels to avoid penalties for feeding too much power back into the grid and to avoid overloading the grid. Finally, the EV controller ensures that electric trucks or cars can always be charged, even when there is insufficient power from the grid. To do so, the software continuously calculates the available power based on solar energy generation, grid capacity and battery status.

2. Optimizers fine-tune energy management

Optimizers determine the best charging and discharging strategies for the battery system, enhancing a business’s energy management resulting in (additional) revenue streams. These software services aim for optimal results based on specific priorities.

What exactly does the software do?

The PV optimizer maximises the use of solar power by ensuring that the battery is discharged at the right time to make way for newly generated solar power and is fully charged in time for the next peak in energy demand. This is done based on expected power generation and consumption, and restrictions on feeding solar power back into the grid. If the solar panels produce more energy than is needed to run the business, the EPEX optimizer allows energy to be traded. This means that a company can take advantage of fluctuations in energy prices by buying energy cheaply and selling it at a higher price on the day-ahead market. For companies with electric vehicles, the EV optimizer increases revenue by applying the optimal charging and discharging strategy of the battery into the vehicles based on HBE’s, energy prices, energy markets, solar power production and, of course, EV consumption.

3. Advanced modules maximise revenues through customisation

Advanced modules maximise the impact and revenue of a smart battery. They are fully tailored to the specific needs of the customer, site or project.

What exactly does the software do?

API access allows the battery system to be linked to different internal or external data sources, such as driving schedules and much more. With the ability to connect to other data sources, the possibilities for making the battery even smarter are endless. The Advanced trading module allows the parties that are responsible for maintaining balance between electricity supply and demand on the energy grid to integrate the battery into the balancing markets. Providing a smart battery as a buffer for energy balancing opens up yet another revenue stream.

How we do it

At iwell, we develop all the intelligent software for our batteries in-house. This allows us to tailor each battery to the needs of the customer. There’s a dedicated team of software developers working every day to fine-tune and improve the software.
