Who we are
We provide a data driven machine learning solution with the purpose to predict lithium-ion batteries (complete) lifetime from 1st life to end of life.
Sustainability, commitment, innovation, idea and joyfulness.
Creative thinking for the planet.
Sustainability and control.
Service that provide savings, but also understands the lifetime of the battery.
The AiTree Cloud solution
We use the data from the first life lithium-ion application and combine that with our inhouse developed algorithm to calculate the lithium-ion batteries complete lifetime.
The benefits with AiTree Solution
• Create next generation of smart, safe and cost-effective lithium battery solutions.
• Understand the scenario with re-manufacturing.
• Analyse data and optimize the battery size to better understand the lifetime. 1st life? 2nd life? End-of-life and recycling?
• Significant reduced test and verification.
• ID tracking for reporting to authorities.
= That gives you stability and control.

“There is no question that the electric vehicle has a great future”. Surprisingly, it is not Elon Musk who is credited with these words, but W.C. Anderson, president of an electric car company, a little over a hundred years ago. Unfortunately, they were uttered a bit too early, in 1912 – at the same time as Ford was breaking sales records with its Model T, mobilizing the masses at an unbeatable price of 650 USD (roughly 17000 USD today). The future of electric vehicles looked bleak as the world embraced fossil fuels. And now ours does as well, for very similar reasons. The incredible progress in mobility needs to be put on a sustainable foundation for us not to go the way of Mr. Anderson’s products. Of course, it would help not to repeat the mistakes of the past – after all, it was the energy density and abundance that made oil the dominant energy source. Which brings us to batteries.
The wind of change
Kickstarted by the need for portable electronics such as phones and laptops and fueled by the increasing demand in storage capacity, battery technology has seen unprecedented improvements over the past decade. Nevertheless, even the most advanced battery types share a common trait – they degrade over time, decreasing the amount of potential energy (or capacity) they can store. After they drop to about 80 % of their nominal capacity – typically after several thousand cycles – they are considered at the end of their so-called remaining useful life (RUL) and usually discarded. But the end of RUL does not have to mean retirement. Batteries are prime candidates for second-life applications in systems featuring lower requirements, stationary applications or auxiliary units. But how can we determine how long the battery has left until absolute failure? After all, any investment in cycling applications requires a safe assessment of remaining capacity and projected degradation trajectory. Enter another promising field experiencing rapid growth – machine learning.
The AiTree – proof of concept
One can argue that the most crucial part of machine learning is acquiring well-annotated data. Even the most complex model will not be able to make sense of a dataset that is too small, missing key variables or of poor quality. Without good quality data, the model choice or parameter tuning is of little importance. The team behind “Data-driven prediction of battery cycle life before capacity degradation” (Severson et al., 2019) provides an extensive dataset monitoring battery degradation. In their paper the authors claim the dataset to be the largest publicly available dataset so far, containing close to 97,000 charge-/discharge cycles of 124 commercial LiFePO4 battery cells.
During the charge-/discharge cycles, the team continuously monitored voltage, current, temperature and internal resistance of the batteries. External factors influencing battery degradation were limited during the data generation process by performing measurements in a temperature-controlled environmental chamber set to 30 °C. The batteries were subjected to varied fast-charging conditions to facilitate different degradation rates while keeping identical discharge conditions.
