Compliance Testing of Batteries Battery diagram The battery, which bears the responsibility of delivering all of the energy in an electric vehicle, must offer safety and a long service-life. An EV usually contains hundreds or even thousands of battery cells, and safe operation is dependent on maintaining consistent stability for all the battery cells in use. In order to ensure consistent electrical characteristics when a s s em b lin g bat ter y c ell s into m o d ul es, a s s es s m ent a n d screening of individual cells are required. Positive electrode Negative electrode Ion movement in electrolyte...

Test High-voltage Battery Packs Conduct high-voltage DC testing at 1000 V with the BT3564. An anti-spark function prevents arcs or sparks that tend to occur during high-voltage testing. Connection Testing of Battery Systems Test DC resistance to determine the connection state Resistance range: 0.00 μΩ to 1200 MΩ; resolution: 0.01 μΩ Check the reliability of electrical connections and the connection tabs and wires in a battery system. When there is a defect in the welding, resistance will increase in the joints, leading to heat emission and damage during charging and discharging. You can monitor...

Test multiple points simultaneously Record ECU Signals Due to the development of the electronic control units (ECU) in vehicles, automotive sensors are becoming more miniaturized, multifunctional and integrated. In order to carry out a full set of functional tests for vehicles, sensor signal logging is essential. While multiple channels and high signal acquisition speed are required, the demands on measurement equipment are also increasing. ■ Multiple channels for high-speed data transmission ■ Isolation between channels Wheel speed a Many types of sensors for a diverse range of applications...

Test Electrical Characteristics of Auto Parts In next generation vehicles, the types and number electronic parts continue to increase. To design vehicles with advanced functions, electronic components and parts must be tested in the R&D stage. Test Component Integrity Select the instrument according to your application's frequency range. ■ High-precision testing ■ A wide variety of test fixtures Piezoelectric components Q Test Parameters (Four-component mode) L1 (inductance) C1 (capacitance) R1 (resistance) C0 (parallel capacitance) Qm (mechanical resonance m-quality factor, mechanical quality...

Essential Tools for On-site Maintenance In terms of maintenance, alternative energy vehicles have needs that are different from those of conventional automobiles. To meet increased electrification and power system changes, even more inspections must be conducted during auto maintenance and repair in order to ensure driving safety. Terminal Shutters Prevent Incorrect Insertion of Leads Inspect high voltage wire harnesses After operating a vehicle over a long period of time, continuity and insulation problems may appear in high-voltage wire harnesses. The performance of the harnesses determines...
