Lithium-ion batteries for electric bicycles

Power battery-Lithium-ion battery for electric bicycles is an important part of electric bicycles, and its performance is directly related to the cruising range, service life and safety of electric bicycles. In order to ensure that the performance and safety of lithium-ion batteries for electric bicycles meet the GB/T 36972-2018 standard, ACST provides comprehensive testing services.

The following are the key test items for lithium-ion batteries for electric bicycles:

l I2(A) charge and 2I2(A) discharge test: these tests simulate the charging and discharging of the battery in actual use to evaluate the charging and discharging performance of the battery.

l low temperature discharge and high temperature discharge test: the low-temperature discharge test evaluates the discharge ability of the battery in a low-temperature environment, and the high-temperature discharge test evaluates the discharge performance of the battery in a high-temperature environment. These tests are essential to ensure the reliability of the battery under various environmental conditions.

l cycle Life Test: the cycle life of the battery was evaluated by simulating the charge and discharge cycles of the battery during long-term use. This helps to predict the service life of the battery and provides a reference for the user.

l test of charge retention ability and charge recovery ability: the retention-of-charge test evaluates the battery's capacity retention after a long period of non-use, while the recovery-of-charge test evaluates the battery's ability to recharge after discharge. These tests help to understand the performance of the battery during storage and use.

l charge recovery ability test after long-term storage: this test evaluates the charge recovery ability of the battery after long-term storage to ensure that the battery can still maintain good performance after long-term non-use.

l internal resistance test: internal resistance is one of the important parameters of battery performance. By testing the internal resistance of the battery, the working state and performance of the battery can be understood.

l low pressure, high and low temperature impact test: these tests simulate the operation of the battery under extreme environmental conditions to evaluate the adaptability and reliability of the battery.

l overcharge protection, overdischarge protection, discharge overcurrent protection test: these tests evaluate whether the protective measures of the battery under abnormal operating conditions are effective to ensure the safe use of the battery.

l molded housing stress test: this test evaluates the strength and durability of the battery case to ensure that the battery will not crack or leak during use.
