Publication number: 20250007031Abstract: A system and a method for managing operating temperature and pressure of a battery are disclosed. Cells of the battery are housed in cylindrical modules into which a heat transfer fluid under pressure and at a temperature circulates. A fluidic unit has a return reservoir that collects oil leaving the modules, and cooling and heating reservoirs containing oil pumped from the return reservoir at predefined hot and cold temperatures. Oil is transmitted to the modules at a temperature and a pressure almost instantaneously obtained by regulated mixing and flow rate of hot and cold oil. The mixing and the flow rate are controlled by controllers connected to a BMS which manages oil pressure and temperature setpoints to be applied to the cells as a function of a demand in power and in energy received by the BMS and pressure and temperature measurements taken by sensors in the system.Type: ApplicationFiled: October 19, 2022Publication date: January 2, 2025Applicant: HYDRO-QUÉBECInventor: Serge MONTAMBAULT

Publication number: 20240279055Abstract: The technology relates to a method of producing synthesis gas comprising carbon monoxide (CO) and hydrogen (H2), wherein the synthesis gas is produced by a reduction reaction of a first flow comprising a carbon source and an excess of hydrogen in contact with an Oxy-flame. The hydrogen comes from a reducing stream, a first portion of which ends up in the first flow, and a second part of which is used to generate the Oxy-flame by combustion of the hydrogen in the presence of a second flow comprising oxygen (O2), the second flow coming from an oxidizing stream. The first flow and the second flow are at a distance from each other such that the Oxy-flame supports the reaction between the carbon source and the hydrogen. A reactor, which can have different configurations, is also proposed for implementing the method.Type: ApplicationFiled: April 24, 2024Publication date: August 22, 2024Applicant: HYDRO-QUÉBECInventors: Raynald LABRECQUE, Robert SCHULZ, Michel VIENNEAU, Germain LAROCQUE
