E-MOBILITY
Klaric and Accurate Technologies Inc. (ATI) entered into a partnership in 2019 which leverages the synergies between ATI’s measurement and calibration competencies and Klaric’s competitive advantage in the high voltage sector. These data acquisition systems are optimized for testing new electric and hybrid vehicles making tasks easier, safer and faster. Klaric’s precision measurement modules have CAN, RS232 and Ethernet interfaces for monitoring data output, setting range selection, and making automated measurements or manufacturing line adjustments.

ECU Serial Communication
Battery Management Systems (BMS) Safe Operating Area (SoA) limits relying on CAN to deliver software interpreted hysteresis for a BMS, especially with High Voltage (HV), requiring a device faster than it’s capable of handling. Functional safety is of the highest importance in a BMS. It is critical during charging and discharging operation, to prevent the voltage, current, and temperature of any cell or module under supervisory control from exceeding defined SoA limits. HV systems for reading voltage/current of all cells exceed CAN bus speeds and cause indeterminate decisions. ATI’s A9 ECU Interface is capable of acquiring 125,000 data items, a sample Time period of 50us, and simultaneous DAQ Rates of 500+ independent data rates/raster by having direct communications with supported processors providing real time access to BMS data.

Charge Monitoring
Utilize the Klari charge monitor either between mains connection and charge station or charge station and vehicle to monitor charging curve parameters. The charge monitor is flexible in its monitoring parameters and connection types. Specify the charge connectors to suit your application/region. Measure current and voltage and calculate power, efficiencies and work in real-time. Connect the Klari charge monitor to VISION to synchronize data collection with additional sources or use the built-in logger to never miss measurement events. Connect VISION simultaneously to your VCC to measure and calibrate the charging curves. Finally utilize the Klari Quad / PT modules to measure temperature inside the battery during testing.

Battery Management Systems Testing
Make use of the Klari Quad 2 TB8 to enable up to 16 channel high voltage data acquisition from one device. Measure the thermal and electric properties of the battery pack during charging and discharging cycles simultaneously in real-time. The Klari-Quad supports thermocouple, voltage, current and combination probes to measure all the data required in testing, verification and development of battery packs and their required control modules. Attach ATI’s VISION software to record and calibrate data from the battery management systems simultaneously producing a single time-aligned recording.

HV Powertrain Testing
The Klari Quad 2 enables simultaneous measurements of high voltage, current and temperature from multiple sources on your HV powertrain. The QUAD 2 is designed for in-vehicle use enabling HV powertrain testing whenever and whether you need it. Utilize Klaric’s expertise in high voltage applications with custom breakout cables, boxes containing measurement probes to suit your applications. Breakout boxes and cables can be customized to suit your vehicle to enable quick, efficient and safe installation onto your HV powertrain. Take data from Klaric high voltage data acquisition modules into ATI VISION software to combine with data from controls modules giving the full picture of the HV powertrain.

Motor / Inverter Efficiency Testing
Klaric high voltage modules enable acquisition of both AC and DC voltages/currents with calculations for power, work and frequency. Utilize this with VISION’s high quality post-processing and real-time calculations to test and verify the efficiency of inverter and electric motor combinations. Utilize VISION's advance calibration features to modify control module parameters in real-time whilst measuring output from both sides of the inverter.
