Testing compliant with international WLTP standards requires the precise measurement of current and power integration for charging and discharging of each battery in the system.
The excellent DC accuracy of the PW3390 and the ability to integrate current and power at 50 ms intervals realize ultimate effectiveness and best usability for this application in combination with high-accuracy clamp current sensors.
Test Cycle Example
Current and Power Integration Function by Polarity
DC integration measurement integrates the recharging power and discharging power by polarity for every sample at 500 kS/s, and measures positive-direction power magnitude, negativedirection power magnitude, and the sum of positive- and negative-direction power magnitude during the integration period. Accurate measurement of recharging power and discharging power is possible even if there is rapid repetition of battery recharging/discharging.
Optimal Current Sensors for Automotive Testing
Easily connect high accuracy clamp-type sensors without cutting the cables. Sensors operate over a temperature range of -40°C to 85°C (-40°F to 185°F), characteristics that enable highly accurate measurements even inside the engine room of a car.
