DH7008 portable impedance analyzer Introduction: DH7008 is a portable testing analyzer that can be used for monitoring the health status of lithium battery stacks in engineering sites. The regular version of DH7008 has 19 independent testing channels (16 voltage measurement channels+1 current measurement channel+1 temperature measurement channel+1 insulation impedance measurement channel). Features: 1. Integration, miniaturization, lightweight, and convenient use 2. Intelligent monitoring of battery status 3. WiFi communication, automatic transmission of data and alarm signals to the user's mobile terminal 4. It can simultaneously monitor the voltage and AC impedance of each battery in the lithium battery stack, the insulation impedance of the battery to ground, and the temperature inside the battery module 5. Synchronous sampling Technical parameters: Number of channels: (16 voltage channels+1 current channel+1 temperature channel+1 insulation impedance channel)/unit Peak output maximum AC current: ± 2A (± 1.4A RMS) Maximum output power: 120W Maximum isolation voltage: 1000V Current range range: 2A Voltage range range: 50mV; 5V (2nd gear) Measurement voltage range (open circuit potential): ± 5V Voltage acquisition accuracy: ≤ ± 0.1% (FS) Input impedance of each acquisition channel:>100M Ω EIS measurement accuracy: ≤ ± 2 ‰ Impedance measurement frequency range: 0.1Hz~10kHz Impedance scanning method: linear or logarithmic Communication interface: WiFi Power supply: 220VAC/30~60VDC Minimum impedance measurement of battery stack cells: 10 μ Ω Electrode connection method: four electrodes Test results presented: battery impedance, temperature, spectrum, and data table
