What are the test methods for traditional batteries?

Traditional battery test method 1. Basis for traditional battery test At present, almost all the batteries used in cars in the world are batteries. The biggest feature of the battery is that the battery gradually ages as the battery is used. When the battery capacity decreases to its original rated capacity At 80% of the time, the capacity of the battery may drop drastically. At this time, although the battery may still be able to supply a certain amount of energy, it may be scrapped at any time. In the international and domestic battery industry, 80% of the battery capacity is regarded as a critical point of the battery. When the battery capacity is reduced to 80% of its original rated capacity, the battery must be replaced. 2. The traditional method of judging the health of the battery The traditional method of judging the health of the battery is the discharge method. Generally, the current actual capacity of the battery is tested by discharging to determine the health of the battery. Regarding car batteries, the International Battery Association (BCI) stipulates that at room temperature, discharge at 1/2 of the rated cold start current value for 15 seconds. If the battery voltage is above 9.6V, the battery has passed the discharge test and is healthy Battery. 3. Insufficient performance of traditional detection The traditional method of adding a load to test the battery has the following performance: (1) The battery under test must be fully charged, at least 12.4V, because the test principle is discharge, if the test object is already Partial discharge will inevitably lead to a low voltage value of the measurement result and cause misjudgment; (2) Regarding the same battery, the measurement cannot be repeated continuously, and the same result can be obtained. Since the test process is the discharge process, the battery under test must be recharged after the test before it can be measured again; (3) The test process emits a lot of heat, which makes it impossible to continuously test multiple batteries; (4) The test process requires the tester to train Well, because the voltage value of the battery must be read at the moment of discharge for 15 seconds, the level and sense of responsibility of the operator will affect the test conclusion.
