Performance
Avoid conservative buffer and unlock competitive edge in performance.
Sthir Performance Suite delivers consistent and reliable performance through accurate state estimation and health aware dynamic fast charging controls.
Industry Challenges
Vehicle Range & Energy Utilization
Unreliable estimation leads to sudden vehicle stoppage & increases range anxiety, making the vehicle less competitive, reducing potential sales revenue
Accelerated degradation
Poor power limits and cell imbalance lead to operating cells outside the safe operating area. This accelerates battery degradation and sometimes even causes a hazardous event
Production Cost & Margins
Inaccurate state estimate forces to add larger capacities to guarantee performance, raising production cost and compressing margins
Health-adaptive State of Charge
Sthir algorithm delivers SOC estimates with up to 97 % accuracy over the entire operating range and throughout the life of the battery
Fast Charging Control
Fast charging control predicts battery internal states in the future and makes a decision considering battery degradation as well as the safety operating area
Dynamic Operating Power Limits
Sthir uses advanced model-based control to estimate power limits for the next time horizon to avoid sudden de-rates/cutoff
Energy based Balancing
Unlike traditional voltage based balancing, Sthir estimates usable energy left in each cell to balance the cell energy differences
