Technical Field

The invention relates to the field of battery testing, in particular to a battery testing method and equipment.

Background

A battery of a conventional electronic device, for example, a battery of an electronic device such as a mobile phone or an ipad, needs to be subjected to a system test before being shipped from a factory, so as to ensure that the battery does not fail in subsequent use. The battery of the conventional electronic device is usually tested at normal temperature by using a battery test cabinet.

However, the inventor finds that the battery of the unmanned aerial vehicle is tested by adopting the traditional battery testing method of the electronic device, and even if the battery passes the test, the unmanned aerial vehicle still can be caused to explode frequently when being used on the unmanned aerial vehicle. Subsequently, the inventor carries out a plurality of troubleshooting and a plurality of tests, and finally finds that the main reason is that the traditional battery test method of the electronic device cannot be suitable for the real use environment of the battery of the unmanned aerial vehicle, so that whether the performance of the battery meets the special use environment of the unmanned aerial vehicle or not cannot be found during the test. Because the unmanned aerial vehicle needs to be used in different environments, the environmental span is sometimes very large, such as severe cold and severe summer, for example, the battery of the unmanned aerial vehicle may be charged at the ambient temperature of 20 ℃ and 35 ℃ and at the ambient temperature of room temperature, and may be discharged and used at the outdoor ambient temperature of-40 ℃, 30 ℃, 20 ℃, 0 ℃, 40 ℃, 50 ℃, 60 ℃, 85 ℃ and the like, the environmental temperature span where the battery is charged and discharged is large, and the performance of the battery at different temperatures needs to be tested, so as to determine whether the battery meets the use requirement of the unmanned aerial vehicle.

To the battery performance test of the above-mentioned large environmental temperature of span, the inventor adds a temperature control box on traditional test mode battery test cabinet basis, if need carry out the battery test under the different temperatures then need two equipment cooperations of battery test cabinet and temperature control cabinet to use, when the battery test, need earlier trompil earlier on the temperature control cabinet and walk the wire, carry out the electricity with battery test position in the temperature control cabinet and connect, and put into the battery test position in the temperature control cabinet with the battery and carry out test operation. However, the inventor finds that the testing method still has the defect that the operation process needs manual adjustment of the temperature control cabinet to realize the testing of the battery at different temperatures. For the battery test of the unmanned aerial vehicle, the test temperature span is large and the temperature needs to be changed at intervals. The prior testing device is not linked and complicated in operation, so that time is delayed, misoperation is easy to occur, and the use requirement of a user cannot be met. In addition, the temperature control box is provided with holes, which also affects the accuracy of temperature control.
