Data Acquisition | Energy · 3 min. reading duration

Optimizing the energy efficiency of electrical systems remains a continuous challenge. To address this, HIOKI has designed an innovative multi-channel current measurement solution tailored specifically for development teams in the electrical and e-mobility industry. For the first time, even the smallest currents in an Electric Vehicle (EV) or other electrical systems can be measured and logged individually by using ultra-compact, high-precision current sensors. By analyzing this data, engineers can gain valuable insights and draw conclusions on how to significantly improve energy efficiency.

Increase Energy Efficiency for Electrical Systems

Accurate current measurement of numerous consumers in electrical systems requires sensors with utmost precision. HIOKI’s new AC/DC zero flux current sensors CT7812 (2 A) and CT7822 (20 A) allow engineers to measure currents with an impressive accuracy of ±0.3 percent. With such high precision and a minimum resolution of 0.1 mA, development engineers can obtain accurate consumption data even for low currents. This detailed information allows for significant improvements of the system energy efficiency contributing to longer operating times or extended driving ranges of EVs.

Ultra-Compact Zero Flux Current Sensors for Narrow Spaces

HIOKI’s new current sensors also impress with their ultra-compact design. With a total length of only 7.65 cm and a user-friendly sliding mechanism the sensors allow for an effortless connection to various consumers. Measurements in confined spaces such as in engine compartments, enclosures, or electrical cabinets can now be realized even under extreme temperatures.

Figure1: New current sensors – precise measurement and easy handling in confined spaces.

Reliable long-term logging

A data logger is designed to record over extended periods of time. For this reason, it is crucial that the current sensors employed exhibit no drift. HIOKI’s current sensors, equipped with the advanced fluxgate technology, provide temperature compensation, ensuring stable and accurate data acquisition for long-term measurements, even under fluctuating and extreme temperature conditions ranging from -40°C to +85°C.

Effective Current Mapping with 55 Measurement Channels

For effective and precise current mapping, the two new current modules LR8536 and U8556 provide in combination with the Data Logger LR8450-01 up to 55 current measurement channels. Alternatively, the LR8450-01 supports logging a wide range of signals, including temperature, strain, vibration, humidity, resistance, voltage, current, and CAN. Depending on the selection of modules and measurement parameters, the logger set up can be extended to max 330 channels, offering engineers a comprehensive solution to evaluate the Device Under Test (DUT) considering all parameters at once. In addition, the use of wireless modules allows for a lean, efficient set up even in complex electrical systems such as in EVs, trucks, construction vehicles, or agricultural machinery.

Wireless Connection Now Possible

Another highlight of HIOKI’s new multi-channel current measurement solution is the high flexibility provided by its wireless capability. The LR8450-01 is the first data logger to use wireless modules, enabling a spatial separation between the current sensors and modules and the data logger. This capability saves time and gives development teams more flexibility for their set ups, allowing for faster assessment of the energy efficiency of electrical systems, particularly in the field of electromobility. With its wireless measurement capabilities and the integration of a current measurement functionality, the LR8450-01 stands out as one of the most versatile and efficient data acquisition systems for a wide range of industrial applications.
