• Current precision: plus or minus (0.05% RDG. Plus or minus 0.05% mg.)
• Quick response testing technology: the current rate of climb 50 ms (90% to 90%), applicable to a variety of test application requirements
• Support dynamic condition simulation (Waveform) test function, the simulation of the actual driving conditions current or power status, support NEDC test standard, FUDS, HPPC regulations

High frequency sampling measurement technology

General battery charging and discharging machine, direct use of power calculation software reads the current value, software of data read speed limited, however, will have the affect of dynamic current capacity calculation error is too large.Chroma increased by V/I sampling rate, and through the two integral method, provide better capacity calculation, accurate current change when the data is not missing, not affected by the data transfer rate.

• V/I 50 KHZ sampling rate (every 20 mu s sampling point)
• Piecewise integral mode operation: for I integral - electric capacity;The V x I integral - energy

Quick response testing technology

In the current rapid response at the same time, can achieve the optimized charging and discharging mode conversion control, avoid damage to the object under test test process.

• The Current Ripple, whose < 1% FS, Overshoot < 1%

Working condition of dynamic simulation function

The use of the battery pack is fast and irregular current charge and discharge change state, through the results, the use of the battery status can be real reaction in the battery.

• Dynamic charge and discharge Waveform of simulation battery actual use, in the dynamic current mode (Waveform), maximum discharge and the maximum charging current commutation time only need 10 ms
• Work within the computer specified step can be set to read current/power waveform Excel file
• Each channel can store 720000 points, for long time dynamic testing
• Working condition of waveform changes the time interval of 10 ms ~ 10 SEC.

Chroma 17020 e test system software platform 'Pro, conforms to the requirement of each test the secondary Battery, with a high degree of stability and security, and have power data save reply function, to prevent any possibility of data missing.

• Real-time monitoring: real-time browsing system test status, do not need to wait for, channel data and system integration can browse at the same time
• Graphic management: channel test status through different graphic management, be clear at a glance, easy to see to understand easy to understand, control state immediately, understand the test state
• Data analysis functions: customized charts function, rapid test curve drawing (Life cycle, Capacity report...Etc.)
• Fault record tracking & permissions Settings: independent record abnormal state channel;To set the user authority to operate

• Through software can integrate constant temperature and humidity box, charging and discharging test do synchronization setting conditions
• Through software can integrate data record, in the process of charging and discharging, read more groups of voltage and temperature record, the condition can be converted to protect start-up condition or cut-off condition

• Through the communication interface software can be integrated device, the choose and buy A692000 / A692001 each of the 4 channel / 8 channels of communication unit, can do the CANbus, RS485 communication, in the process of charging and discharging, read more groups of battery management system (BMS) data, its condition convertible protection start or cut-off condition
