Some batteries can be charged fast, but the faster a battery is charged, the faster it degrades. To avoid irreversible damage, manufacturers often limit the charging rate of batteries.
Nearly all off-the-shelf lithium-ion batteries that are charged with GBatteries’ adaptive pulse charging algorithm — as an alternative to CCCV — can be charged faster and without compromising cycle life.
ChargeSense is a proprietary, fully adaptive, self-learning algorithm that generates complex charging pulse profiles based on real-time monitoring and analysis of a battery's internal state. Unique charge profiles are generated based on battery response signatures in real-time, which result in a drastic reduction of irreversible chemical reactions.
GBatteries’ hardware consists of off-the-shelf components, but utilizes proprietary novel architecture that generates precisely engineered pulses at high frequency. All of the hardware is designed, developed, and built internally.
With every pulse, ChargeSense detects and charges the battery during the low impedance phase, until a critical point in R(t) is reached — Pausing for a crucial period of time to allow a small amount of depolarization and impedance to drop, to prevent irreversible chemistry from occurring.
Impedance is a dynamic parameter of a battery that changes rapidly with time during charge. Impedance is also affected by battery state of health, charge and even ambient temperature.
Faster charge often results in a rise in battery temperature, demonstrating possible irreversible internal damage and a potential safety risk. As GBatteries' charging protocol adapts to operate in lower impedance periods, the result is a lower temperature rise during ultra-fast charging.
