Under the hood: what is BattGenie?
BattGenie provides software solutions for battery management systems (BMS). BMSes are electronic control circuits that monitor the battery’s internal states (such as State of Charge (SoC) or simply how much charge is left in the battery) and regulate the battery’s charging. If you have a rechargeable battery powering up a device or electric vehicle near you, you’ll surely find a BMS there.
What makes BattGenie unique?
BattGenie uses physics-based battery models (porous electrode P2D models) to simulate and control the battery in any application. Depending on the battery materials and usage conditions, the physics-based models account for various physical degradation phenomena such as
Li-plating, SEI layer formation, intercalation-induced stresses, and so on. Using our patented mathematical techniques, these models are used to calculate and implement optimal charge profiles, enabling batteries to be charged in under 15-min. without compromising on cycle life.
How do optimal charge profiles help?
Optimal charge profiles can extend battery cycle life and enable faster charging. These in turn have many other benefits.
Extended battery life means a greater range of the EV.
The usage time of the battery will increase, before the need to recharge it again, because of larger battery capacity.
More range/usage time means the same performance can be extracted from the battery at a reduced battery size and weight.
Reduced battery weight in EVs will make them lighter with better acceleration.
Reduced battery size and weight in consumer electronics, large building complexes, grid storage will make these solutions more economical.
Optimal charge profiles will also control battery temperature and swell more efficiently. This will lead to safer EVs, consumer electronics, and other applications.
We have demonstrated battery cycle life improvement in excess of 100%
Compared to traditional methods of battery charging through independent testing at National Renewable Energy Labs (NREL).
Engineered to be universal
Through our patented in-house numerical solvers and optimizers, we’ve developed and tested BattGenie’s algorithms on a range of microcontrollers. BattGenie’s algorithms can be solved in milliseconds on any controller.
