All batteries start to die from the first day you power on your new mobile device. Within months you notice it lasts considerably less. Add fast charging - it gets noticeably worse. It turns out that the simple way batteries are charged today causes most of the damage that leads to shorter daily battery life, reduced lifespan - and diminished safety.
Qnovo takes a unique, innovative approach to solving this age-old problem. By applying intelligence to the charging process using software algorithms, we enable mobile device makers to give you a safer and better mobile battery experience: faster charging, two year battery lifespan and more daily use as your battery ages.
Qnovo adaptive charging is based on a real-time control system with closed-loop feedback, which provides an additional level of safety over open-loop CCCV or step charging.
Qnovo's patented Adaptive Pulse Modulation™ injects charge packets both to measure a cell's health and to adaptively modify its charging parameters.
Through controlled stimulation of the battery throughout a charge cycle, Qnovo continually diagnoses a cell's electrochemical processes in real-time.
Real-time EIS provides unparalleled visibility into chemical health, which enables Qnovo algorithms to reduce cell damage over time. Safety checks are performed hundreds of times each charge cycle, allowing safe shutdown of problem cells.
