The user can choose to resume or restart testing.High frequency sampling measurement technology – improving measurement accuracyV / I sampling rate: 50 KHz (∆t 20 µS)Generally, battery testers use software to read current values for calculating power; however, limited data sampling rates could result in large errors when calculating the dynamic current capacity. By increasing the sampling rate and using a double integration method, Chroma 17011 is able to provide a capacity calculation with much higher accuracy. When the current changes, the data is not lost and the transmission speed is not affected.* Note: The current response time <100 µS applies to model 17216M-10-6, the impedance of other UUTs will slightly differ.General charger/discharger sampling rateChroma charge & discharge tester sampling rateHPPC TestHPPC test applicationHPPC is a test procedure developed by the USABC (U.S. Advanced Battery Consortium) for the battery power performance of hybrid and electric vehicles. Within the batteries operation voltage range, the procedure mainly establishes the function of the relationship between the depth of discharge and power and, secondarily, establishes the depth of discharge, conductive resistance and polarization resistance function via the voltage and current response curve from discharging, standing to charging. The measured resistance can be used to assess the battery's power recession during later life tests and its equivalent circuit model development. Chroma 17011 has a flexible editing program that allows HPPC testing.DCIR test (2)DCIR test (1)Lumped parameter model circuit diagram Battery capacity test applicationT h e c a p a c i t y c a n b e o b t a i n e d a s t h e i n t e g r a l o f t h e c u r re n t integrating the current versus time from the start of charging/discharging until the cut-off condition is reached. The comparison results are useful to analyze performance differences between products, and the common test items include current ratio and temperature characteristics tests. Higher accuracy of current, voltage measurement and faster sampling enable to distinguish more accurately the differences in battery cell capacity.Battery cycle life test applicationCycle life is one of the most important test items for batteries. In accordance with the experimental purpose, it tests the same battery through repeated charge and discharge conditions until the capacity falls to 80%, and calculates the cycle numbers. The cycle life test can be used to evaluate the battery performance or define the applicable conditions of use.Battery DCIR test applicationThe internal resistance value is related to the charge/discharge ratio of a battery. The larger the internal resistance value, the lower the efficiency when temperature rises. According to the lithium-ion battery equivalent circuit model, the ACIR measurement of traditional 1KHz LCR meters can only evaluate the conductive resistance (Ro) of the battery that affects the instantaneous power output, but is unable to evaluate the polarization resistance (Rp) produced during electrochemical reaction. The D CIR evaluation includes the ACIR that is closer to the actual polarization effect of battery under continuous power applications.The Chroma 17011 includes two types of D CIR test modes: DCIR test (1) calculates the DCIR value using the voltage difference caused by the change of one-step current, DCIR test (2) calculates the DCIR value using the voltage difference caused by the change of two-step current. Users can select the desired test mode and automatically, without any manual calculation, get the results that comply with IEC 61960 standards.CapacitydQ/dV vs voltageCoulombic efficiency test Incremental capacity analysis applicationThe high precision voltage measurement and V sampling function can draw dQ/dV versus voltage curve diagrams to analyze battery cell characteristics and capacity degradation.Coulombic efficiency test applicationCoulombic efficiency (CE) is calculated by the charge/discharge capacity ratio when the battery is fully charged and then fully discharged. Good batteries have higher coulombic efficiency, and need high precision and stable equipment to distinguish differences. An accurate coulombic efficiency test can estimate the batterylifespan with only a few cycles.EDLC capacitance (C) test applicationIn accordance with the Straight Line Approximation Method of the IEC 62391 testing standard, before measuring the capacitance (C) value, the ED LC first needs to be fully charged through a CC-CV charging mode. The capacity test is to discharge CC via the above discharge current. Then, the electric potential difference ( V) of two reference points on the discharge curve are taken against the time difference ( t) and the discharge current (I) to calculate the capacitance value of the EDLC.EDLC combined DCR and C test applicationChroma 17011 also has a direct current resistance (D CR) and capacitance (C) combined test application. Under the same CC-CV charged and CC discharged conditions, the user can use the electric potential in the chosen reference points to simultaneously calculate the DCR and C values of the EDLC to save testing time.The equivalent circuit model development of the classical EDLC includes an equivalent series resistance (ESR), a capacitance (C), and an equivalent parallel resistance (EPR). The ESR is used to evaluate the internal loss and heat of the EDLC during charging/discharging; the EPR to evaluate the leakage effect in the EDLC's long-term storage; the C to evaluate the EDLC cycle life.These parameters are not easily directly measured in a laboratory; researchers need data analysis and complex calculations to determine these important indicators. Chroma 17011 is equipped with the IEC 62391 testing standards and the user can use charge/discharge tests to obtain the ED LC parameters values, in order to evaluate the EDLC characteristics and cycle life.ED LC direct current resistance (D CR) and equivalent series resistance (ESR) test applicationChroma 17011 offers ED LC direct current resistance testing function compliant with test standard IEC 62391. Before testing, the ED LC has to be CV charged. The capacity test is to discharge CC via the above discharge current. When the discharge is completed, get the linear section on the discharge curve and extend it to discharge time and then get the voltage difference of rated voltage and discharge current to calculate the DCR value.EDLC equivalent circuit model developmentVoltage Characteristic Between EDLC TerminalsVoltage Characteristic Between EDLC TerminalsVoltage Characteristic Between EDLC TerminalsCharge/discharge performance and cycle life test applicationThe built-in direct current resistance (D CR) and capacitance (C) test modes can be combined with cycle function and variable set testing conditions to test the EDLC load endurance and reliability. After testing, the user can directly export DCR vs Cycle No. and Capacity vs Cycle No. reports to analyze the EDLC failure and deterioration mechanisms.Self-discharge test modeCoulombic efficiency testAutomatically change current range in CC-CV modeCharge-Discharge Rate Test Charge-Discharge Cycle TestingCoulombic efficiency test applicationChroma 17011 is equipped with low noise, automatically switching current range, and cut-off report as to quickly output accurate c u r re n t c h a rg e /d i s c h a rg e. T h e c o u l o m b i c e ff i c i e n c y (C E ) i s calculated by the charge/discharge capacity ratio, which indicates the ED LC internal capacity conversion as available capacity. A highly accurate CE is an important marker to distinguish differences between products.Leakage current test applicationED LC leakage current measurements generally need to CC-CV charging until a specific time and then it measures this tiny charging current, which is seen as leakage current. The Chroma 17011 CC-CV mode can automatically change current range without output interruption. Under stable voltage, the current range can be as small as 200µA.Current (A)Self-discharge test applicationChroma 17011 also has a built-in self-discharge test mode, when the ED LC is fully charged it can test the charge/discharge for a set time period. When this mode starts, the system will cut off the measuring circuit to provide the ideal open circuit and solely measure the starting potential (V1) and cut-off potential (V2). The software can automatically calculate the electric potential difference ( V).CE=Q Discharge / Q ChargeThe Chroma 17011 test systems are controlled by computer software with diverse functions for testing energy storage products.

LED驱动电源的检测经验
LED 驱动电源的检测经验1、检测方法：由于LED 驱动电源是恒流控制，理论上我们将其看做是恒流源，从电学理论上知道，恒流源不能开路，再加上电子负载机的特点（前端通电后才能够加载电流），因此，不能使用常见的电子负载机测试。
（电子负载机上得到的现象是：数字跳变，会误判驱动电源故障）制作负载：a 、购买3个200欧姆100W 的线绕可调电阻，前1个电阻的可调端（接线后面用鳄鱼夹，以方便调节电阻个数）接在后1电阻的前端，如此3个电阻串联，然后再串联1个大功率1W 的LED 并联组（6个1W 的LED 并联），前面的电阻的前端与LED 的后端的2个分别引线，按照LED 的+、—作为负载的-、+极；(6个并联的1W LED 可以通过的电流将达到2A ，至少不会因为电源的故障而引起烧毁LED 灯板 )b 、将此组合作为LED 电源的负载接在LED 驱动电源的对应输出引脚，其间串联1个电流表;c 、用万用表的二极管档分别测试交流输入端、整流后的+、-端是否有短路，没有，则可以通电；d 、在此负载2端接上万用表的对应+、-表笔 ，万用表置于大于LED 灯板串联数的总电压（LED 串联数*LED 的电压降，通常是3.3V ）的档位， 调整电阻个数及接入电路的电阻的可调端，使得到的电压等于成品LED 板串联的总电压；e 、从电流表上读出的电流数，就是你的驱动电源在此LED 串联数条件下的输出电流；f 、 如果担心电流表的内阻影响驱动电源的输出电流，那么可以选几个精密金属膜电阻并联，得到1欧姆以下的电阻（用电桥测量得到其准确的阻值），串联在线路中，通电后用万用表测量此电阻两端的电压，通过计算得到整个电路的输出电流。
2、仪器从LED 驱动电源设计、检测的角度，至少应该具有以下三种设备：a 、可调交流电源，品牌如Chroma ，如果因为成本问题，可以选购大陆生产的；或者是自藕变压器，但220V 交流输入端需要接个1A 的保险丝（焊接型或电工保险（盒）丝或交流过流保护开关），避免驱动电源出现短路故障而引起市电跳闸；b 、示波器，依据自身的条件选购，最低要求是2G 、500M 2通道；c 、数字万用表，建议是4位半以上，按照上面的使用，最少3个。
