Publication number: 20240006673Abstract: Disclosed are methods, systems, and devices for charging a battery pack based on a temperature of the battery pack. The temperature of the battery pack is determined and compared with a reference temperature value. In response to determining that the temperature of the battery pack is less than the reference temperature value, heating-optimized pulses, having a first frequency, are applied to the battery pack. The heating-optimized pulses comprise a sequence of alternating positive and negative pulses, and carry a net positive charge. Concurrent to applying the heating-optimized pulses to the battery pack, the temperature of the battery pack is determined. In response to determining that the temperature of the battery pack is more than the reference temperature value, charging current is applied to the battery pack.Type: ApplicationFiled: December 14, 2021Publication date: January 4, 2024Applicant: Gbatteries Energy Canada Inc.Inventors: Mykola Sherstyuk, Oleksandr Tkachenko

Patent number: 11831186Abstract: Disclosed are systems, methods, and devices for balancing a battery pack that comprises a plurality of battery cells. A first charging protocol to charge the battery pack is employed, and while the battery pack is being charged, a determination is made whether the battery pack is imbalanced. After determining that the battery pack is imbalanced, a determination is made whether a value of the state of charge (SoC) of the battery pack corresponds to a particular range of values. After determining that the value of the SoC of the battery pack corresponds to the particular range of values and that the battery pack is imbalanced, a second charging protocol to charge the battery pack is employed, wherein the second charging protocol is different from the first charging protocol.Type: GrantFiled: October 29, 2019Date of Patent: November 28, 2023Assignee: Gbatteries Energy Canada Inc.Inventor: Mykola Sherstyuk

Patent number: 11641122Abstract: A pulse charging for a battery includes multi-stage voltage conversion. At first stage, an input voltage from a power supply is divided into a plurality of intermediate voltages. At second stage, one or more of the plurality of intermediate voltage are further down converted to generate one or more portions of a charging pulse to be applied to the battery. The down conversion of the input voltage to the output voltage is accompanied by increase in charging current that is applied to the battery. The higher charging current applied to the battery results in fast charging of the battery. Also, the described multi-stage voltage conversion circuitry has high efficiency which alleviates problem of heat dissipation associated with the voltage conversion for charging of the battery.Type: GrantFiled: June 7, 2018Date of Patent: May 2, 2023Assignee: Gbatteries Energy Canada Inc.Inventors: Oleksandr Tkachenko, Mykola Sherstyuk, Aleksandar Prodic, Timothy McRae, Ivan Radovic, Oleksandr Puzakov

Publication number: 20220390522Abstract: Disclosed are methods, systems, and devices for battery formation. A first set of pulses, having a first frequency, and that carry a net zero charge, are applied to a battery. After the first set of pulses are applied to the battery, a second set of pulses that carry a net positive charge are applied to the battery. The second set of pulses are either applied after expiry of a particular time period following the application of the first set of pulses, or based on some battery measurements. After the second set of pulses are applied to the battery, a battery parameter is measured, and based on the measured battery parameter, a third set of pulses, having a second frequency, and that also carry a net zero charge, are applied to the battery.Type: ApplicationFiled: October 20, 2020Publication date: December 8, 2022Applicant: Gbatteries Energy Canada Inc.Inventors: Mykola Sherstyuk, Oleksandr Puzakov, Oleksandr Tkachenko
