Electrical energy consumption meter
Overview
During the development and testing of electric vehicle batteries and motors, current and voltage must be monitored in real time during motor energy recovery and battery energy output. Naiou’s high-performance microprocessor-based acquisition unit measures one channel of voltage, current, instantaneous power and electrical energy consumption. It combines easy operation, multiple communication interfaces, analogue voltage output and a bright, wide-viewing-angle OLED.
Main features
- Electrical energy consumption testing for new-energy vehicles.
- Acquisition of single-channel voltage, current, instantaneous power and energy consumption.
- High-speed data acquisition.
- Measurement of energy output and recovery.
- RS232 and CAN communication.
- Analogue voltage output.
- Accumulated energy consumption can be reset to zero at any time.
- Low-power, high-brightness, high-contrast, wide-viewing-angle OLED readable in sunlight.
