我们对bq27426 RM和FCC 做了精度测试。结果如下图。
我们看到误差有这样的趋势,电流越大,误差越大。温度越低,误差越大。
动态测试比静态测试误差大;
(动态测试是持续放电;静态测试是间歇性放电,放电1%soc,电池静置10分钟)
请问我们猜测的这个趋势是否正确?
We conducted precision tests on bq27426 RM and FCC. The results are shown below.
We see a trend in error: the greater the current, the greater the error. The lower the temperature, the greater the error.
Dynamic testing has greater errors than static testing;
(The dynamic test is continuous discharge; the static test is intermittent discharge, with discharge of 1% soc, and the battery standing for 10 minutes)
Is this trend we are guessing correct?
我们为什么要咨询这个问题,因为我们产品的温度范围是0~75℃,电流范围是0~1400maA,我们为了测试RM/FCC的精度需要做很多实验,但这样做需要消耗太长的时间。我们想找到导致RM/FCC误差最大的实验条件,减少测试的工作周期。请一定帮助我们。谢谢。
Why should we ask this question? Our product has a temperature range of 0~75 ℃ and a current range of 0~1400ma A. We need to do a lot of experiments to test the accuracy of RM/FCC, but it takes too long to do so. We want to find the experimental conditions that cause the maximum RM/FCC error and reduce the test cycle. Please do help us. thank you.
