PARALLEL FUNCTIONS

Parallel function

Multi-channels

• Supports various capacity batteries by paralleling
• The system supports different capacity batteries from a base system configuration
• Battery companies have various capacity configurations. Some customers may purchase a high power system to test all capacity battery packs. The downside is that measurements accuracy are not

 

DRIVING CYCLE SIMULATION

Driving cycle simulation 
The battery pack always is used at quick and un-regular current condition. The system simulates the real condition on battery pack by working condition simulator.

• Import dynamic charge/discharge power or current waveforms to simulate the DRIVE CYCLE or the actual application.
• Support Excel (xls) format
• There are 720,000 points of driving profile memory to save the waveform profile in each channel.
• Minimum Δt：10ms

High accuracy capacity calculation 
Voltage/current sampling rate of 50kHz used for calculations of capacity ratings in dynamic waveform mode.

• V/I sampling rate : 50KHz 
  Minimum data acquisition: 10ms
• Integrate calculus : 
  For I : Capacity 
  For V x I : Energy

Compact Size The dimensions of a regenerative system is smaller compared to a system that has to dissipate energy. Continuous transition  Continuous charge and discharge transition: No time delay to transit from charge to discharge. The user can verify the battery pack for a design limit.  Continuous CC-CV transition: No overshoot current or voltage to damage the battery when transiting CC-CV. Response time The trip time between maximum charge and maximum discharge current is 50ms. Smooth current without overshoot for avoiding to damage the battery. Temperature Measurement Temperature measured for each channel within the range of 0~90℃±2℃. 4 sets of measurements (Max) per channel to measure the battery surface temperature. Independent battery connections  For battery pack design, the charge and discharge connections are independent. Users can set 17020's channels with independent charge / discharge connections to isolate each operation independently. Data Recovery Function 60 min of temporary data storage when sampling time is 1 sec. Save the test settings to resume after power failure is recovered.

SOFTWARE FUNCTION

The 17020 Test system is specifically designed to meet the various requirements for testing secondary battery packs with high safety and stability. Charge and discharge protection aborts tests when abnormal conditions are detected. Data loss, storage and recovery are protected against power failure.
