1、Test ProcedureRoadGME14105Power Generation and Storage - Jumpstart Test1 IntroductionNote: Nothing in the specification supersedes appli-cable laws and regulations.Note: In the event of a conflict between the Eng-lish and the domestic language, the English languageshall take precedence.1.1 Purpose.

2、To define the test conditions for theelectrical and physical functionality at jumpstart andpossible customer errors (Misuse).To investigate if the jumpstart requirement is fulfilled,during certain State Of Charge (SOC) for the battery.The measurements to be recorded are: Charging current Consuming c

The state-of-chargeof the battery is the percentage of available capacity(ampere-hour, but generally thought of as availablepower).1.4.2 Charge Acceptance. Charge acceptance isthe ability of the battery to use supplied ge

5、nerator cur-rent to recharge the battery by reversing the chemicalreactions that occur during discharge.1.4.3 Fully Charge Battery. A fully charged (100 %state-of-charge) battery is one thata hasbeenchargedatavoltageof16Vfor24hwiththe current limited to 5 x I20orb after a CCA test, the charging time

6、 may be limitedto 16 h1.4.4 Soak Time. Soak time is the time a battery ismaintained at a specified temperature without electri-cal stresses or charging to allow the electrolyte andbattery materials to reach the specified soak temper-ature.1.4.5 100 % SOC (Twenty Hour Capacity). TheTwenty Hour Capaci

7、ty is a measure of the total dis-charge ampere-hour capacity of a battery dischargedfrom 100 % capacity until the terminal voltage is10.5 V, at +25 C at a constant current I20for 20 h.The current I20canbecalculatedfromthefollowingequation:1.4.6 Less than 100 % SOC. Start with a fullycharged battery

8、according to paragraph 1.4.3. Calculate the time to discharge the battery at aver-age I20from the following equation:t = 1 - (% capacity desired) x 20 hExample: Capacity desired is 80 %,t = 1 - 0.8 x 20 h = 4 h Calculate the I20from the following equation C20(Ah) = I20(A) 20 (h)Example: Capacity is
