Effect of fuel consumption performance evaluation test on vehicles

This product has the power measurement performance required for fuel consumption measurement according to the new fuel consumption standard "WLTP mode" fuel consumption test, as well as the function of facilitating test implementation. Please review the experimental video.

Performance evaluation test of new fuel efficiency standard WLTP mode

When measuring fuel efficiency according to the WLTP standard, it is required to accurately measure the current accumulation and power accumulation of the charging and discharging of various batteries in the system. The high-precision clamp current sensor and PW3390's high DC accuracy, as well as the 50ms interval current accumulation and power accumulation functions, effectively evaluate the fuel efficiency performance of the vehicle.

Current sensor suitable for vehicle measurement

The high-precision sensor with clamp design can be quickly wired without cutting the wires. The temperature range for use is -40 ℃ to 85 ℃. It has excellent temperature characteristics and can achieve high-precision measurement even in the engine compartment of vehicles.

Accumulation function of current and power with different polarities

The cumulative measurement of DC is to accumulate charging power and discharging power by polarity at a sampling rate of every 500kS/s, and measure the positive direction energy, negative direction energy, and the sum of positive and negative direction energy at the time of accumulation. Even when the battery is rapidly and repeatedly charged and discharged, it can accurately measure the amount of charge and discharge.

Through external control and linkage with surrounding devices

By using an external control button, it is possible to control the start/stop of accumulation and screen copying operations. When evaluating the performance of a real vehicle, it can also be easily controlled through manual switches or connected to other devices for time.

Power measuring instrument: PW3390 that balances high precision and maneuverability

The reading error of the power analyzer PW3390 is ± 0.04%, and the full-scale error is ± 0.05%, achieving very high power accuracy. 200kHz measurement bandwidth and smooth amplitude and phase characteristics up to high frequencies. Used together with the phase compensation function of the current sensor, it can accurately measure high-frequency and low power factor power. Very suitable for evaluating power conversion efficiency or analyzing EV/HEV inverter motors and harmonics.

Power measuring instrument: a power analyzer with rich current sensors to expand the measurement field

Current sensors that are suitable for various measurement scenarios, such as closed mouth type that emphasizes accuracy, high-precision clamp shape that emphasizes convenience, and flexible clamp shape that can measure large AC6000A. From secondary measurement of frequency converters to high current measurement of power lines, various power analyses such as voltage, current, power, harmonics, waveform, and efficiency calculations can be achieved through this compact body.
