中国低温 低温电池
 
当前伴随科技的进步以及对低温温电池的实际应用的需求， 很多领域需要用到低温电池， 尤其是可充的低温电池。
Together with technology’s imporvement and actual demanding of low temperature batteries, there are many field in great demand of low temperature rechargebale ones.
 
当前 中国行业内大多数的低温电池能够承受的最低温度为零下30摄氏度。
Currently, almost all of batteries of China battery line can stand low temperature rate at minus 30 degrees.
 
而某公司生产低温温可充电池能承受的最低温度是零下40摄氏度。
While one company’s low tem battery can stand at most minus 40 degrees.
以LIPO6560158电池组为例， 我们的低温电池还具有如下特征：
For instance, GMB6560158 battery packs, our’s low tem version have following charcteristics as well.

No.	Item	Spec	Note
1	Model	6560158/40Ah	8P7S
2	Charge Voltage	29.4V(single cell 4.2V)
3	Nominal Voltage	25.9V	The average value of voltage during the discharge period (with standard charge and discharge). When shipping, the voltage without load is between 25.2V and 26.95V.
4	Nominal Capacity	5Ah@ 0.2C Discharge Min:4.75Ah	Nominal Capacity refer to the capacity of 0.2C discharge to 19.25V cut-off voltage, after charging with standard method.
		8P: 40Ah Min:38Ah
5	Cycle Life	³ 300 Times	One cycle refer to one charge period and then one discharge period. Test condition: Charge:0.2C to 29.4V Discharge: 0.2C to 19.25V The cycle life is the cycle times when the discharge capacity is about 75% of the rated capacity.
6	Impedance	Cell Impedance: £30mΩ	After Standard charging, measure the internal resistance with AC1KHz (while measuring, clip near 2/3 place of the anode and the cathode.)
		Assemblage Impedance: £80mΩ	Measure two sides of the drawing line after assembling. (Red B+、Black B-)
7	Max. Charge Current	0.5C
8	Max. Discharge Current	1.0C
9	Discharge Cut-off Voltage	≤19.6V
10	Operating Temperature	Discharge: -40℃~ +55℃ Charge: -40℃~ +45℃	Cells must be stored at 25.2V ~ 27.3V. Over long storage periods cells should be cycled every 90 days. The method is to do a charge- discharge cycle with standard method, then charge to 25.2V~ 27.3V.
11	long term storage temperature	-5 ℃~+35℃	Relative humidity: 45~75%RH Voltage:3.8±0.1V(single cell)
