The application discloses a battery electrolyte dosage boundary determination method and related equipment, through scientific calculation and model construction, the electrolyte dosage boundary of the warranty period is accurately determined, and electrolyte injection amount design is optimized. Based on the porosity, volume parameters and electrolyte density of the pole piece and the diaphragm, the pore electrolyte filling amount is accurately calculated to ensure that the electrolyte is fully filled in the internal pores; in combination with the bottom structure parameters of the battery shell and the electrolyte density, the bottom filling electrolyte amount is accurately calculated to maintain the stability of the bottom heat transfer. The internal standard extraction method is used to determine the consumption of formation electrolyte, which is in line with the actual production; with the help of multi-temperature experimental data and the Arrhenius formula, a model is constructed to scientifically predict the electrolyte consumption under the working condition; according to the regression analysis of the volatilization experimental data, the electrolyte transmission amount generated due to poor sealing is reasonably calculated. Finally, the dosage boundary is determined by comprehensively considering the above-mentioned quantities, the performance reduction or cost waste caused by improper electrolyte dosage is effectively avoided, and the balance optimization of performance and cost is achieved.
