If a feature is referred to as being "disposed," "secured," "connected," or "mounted" to another feature, it can be directly disposed, secured, or connected to the other feature or indirectly disposed, secured, connected, or mounted to the other feature.
In the description of the embodiments of the present invention, if "a plurality" is referred to, it means one or more, if "a plurality" is referred to, it means two or more, if "greater than", "less than" or "more than" is referred to, it is understood that the number is not included, and if "more than", "less than" or "within" is referred to, it is understood that the number is included. If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.
The existing battery test generally includes a charge test, a discharge test, a high-temperature discharge test, a low-temperature discharge test, and the like, and after the high-temperature discharge test or the low-temperature discharge test is completed, the battery can be continuously charged until the battery returns to a normal temperature state.
For most battery testers, and to avoid over-charging and over-discharging of the battery, attention is paid to the state of the battery at any time, and especially for discharge tests of single cells, the cell is permanently and irrecoverably damaged by keeping the cell in a discharge state until the battery completely disappears.
On the other hand, in addition to the time consumed by the charging and discharging process of the battery, the inability to start automatic discharging after the completion of one charging process is also an important factor that limits the efficiency of battery testing (for example, when a charging test is performed on the battery after work, the battery is usually charged for about 3 hours at a charging time of 0.5C, a large amount of time is left to only maintain trickle charging or even stop charging, the battery cannot automatically enter the next testing stage, and time is wasted).
In addition, the high/low temperature test in the battery test item is also an important factor that restricts the efficiency of the battery test. At present, the charging temperature range of most batteries is 0-45 ℃, so after the high-temperature (above 55 ℃) discharge test and the low-temperature (-20 ℃) discharge test are finished, the batteries need to be returned to the normal temperature state again and kept for a period of time to be charged, otherwise, the batteries can be damaged, manual operation is needed for switching the charging and discharging test states of the batteries again in the past, and if a tester cannot timely make the batteries enter the next state, the waste of the test time can also be caused.
