摘要
对环境温度为5℃的磷酸铁锂动力电池模块进行预加热后对其充电。结果表明,电池模块在15～20min之间温升最快,加热50min后温度趋于稳定;5℃时充电容量为25℃时最大充电容量的90%;预加热60min后充电容量约为25℃时最大充电容量的97%。
After heating the module of the lithium iron phosphate battery which is in the ambient temperature of 5 ℃, and then the module is charged. The results show that the temperature rise fastest during the heating time 15 to 20 minutes and the temperature tends to be stable after 50 minutes, the maximum charge capacity of the module in- creases to 97 % after heated 60 minutes whose 90% at 5 ℃ of the maximum charging capacity at 25 ℃.
