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: 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

Patent number: 10923923Abstract: A battery pack includes an arrangement of battery cells organized in battery groups connected in series, with each group having one or more battery units connected in parallel, and each battery unit comprising one or more series-connected battery cells connected to a battery switch. Charging of the battery pack uses pulse charging. The charging pulses provided to the battery units can be determined based on one or more measured characteristics of battery cells comprising the battery unit so that charging of the battery units can be optimized according to those characteristics. The charging pulses provided to each battery group are timed so that there is an uninterrupted flow of charging current through all the battery groups at all times.Type: GrantFiled: March 26, 2019Date of Patent: February 16, 2021Assignee: GBatteries Energy Canada Inc.Inventors: Mykola Sherstyuk, Oleksandr Tkachenko

Patent number: 10566817Abstract: A battery charging circuit can produce a pulsed charging current to charge a battery. During charging, without disconnecting the pulsed charging current from the battery, EIS measurements can be made. In other words, the pulsed charging current can serve double-duty, for battery charging and as a drive signal for the EIS measurements. The EIS measurements can be used to alter parameters of the pulsed charging current to improve battery life. In some instances, the parameters of the pulsed charging current can be momentarily changed for the purpose of making the EIS measurements, and then restored subsequent to making the measurements to parameters suitable for battery charging.Type: GrantFiled: April 2, 2019Date of Patent: February 18, 2020Assignee: GBatteries Energy Canada, Inc.Inventors: Oleksandr Tkachenko, Mykola Sherstyuk
