Ensure that your energy system is reliable and efficient by evaluating its overall energy efficiency. Efficiency can be verified based on fuel economy measurements that comply with the international WLTP regulation. This requires the precise measurement of current integration and power integration for recharging/discharging of each battery in the system.
Evaluate the efficiency of the entire system by testing the charge and discharge of the completed battery system in various operating modes and high/low temperature environments.
To understand the electrical dynamics of an xEV, test vehicles are being equipped with measuring systems that can register the energy consumption or regeneration under „real life“ circumstances. The PW3390 combined with one of the clamp-on current sensors of the CT684x series is ideal for this kind of test. The high accuracy, even at short update rate of 50 ms, and the practicality of the CT684x clamp-on sensors guarantee ease of use and accurate data even at low and high temperatures.
