| Abstract: |
| The work aims to verify the functional performance of lead-acid batteries in the low-temperature environment of the polar region and investigate the relationship between the low-temperature environmental factors and the loss of function and performance degradation of lead-acid batteries. Based on the environmental simulation test, the low-temperature storage and low-temperature discharge characteristics of lead-acid batteries were analyzed under the fixed temperature values from –30 ℃ to 0 ℃. In the storage test, as the temperature decreased, the internal resistance of the battery increased and the starting current decreased, and the changes of internal resistance and starting current had a tendency to accelerate. By –30 ℃, the starting current of the battery had dropped to the cold cranking ampere value of 280 A. In the low-temperature discharge tests, as the temperature decreased, the voltage rate drop went higher. The discharge curve showed a tendency of rapid decline in the initial stage-slight rebound-slow decline-steep decline towards the late cut-off voltage. The low temperature induces the increase in electrolyte viscosity, decrease in concentration, and increase in internal resistance, which affects the storage and discharge performance of lead-acid batteries. As a result, the low-temperature adaptability and usage ability of lead-acid batteries are significantly reduced. |
