TOOL BRIEFING Do you have the right tools for an EV repair job? Variable voltages and currents with dozens of interconnected modules make repairing these systems much more dependent on the proper selection and utilization of tooling. By Christopher Groff, Contributing Editor p Figure 1 - Multimeter and accessories. H ybrid and electric vehicles (EV) are becoming a larger share of the vehicle market, meaning repair facilities are handling more routine service and repair work. There is no doubt that they can be a viable profit center for an appropriately trained and equipped business. Understanding system operation and safety precautions have never been more critical with the high voltages found in EVs and hybrids. While a conventional vehicle's electrical system is operated entirely on a 12V DC system, today's electrified vehicles may produce five or more different circuit voltages, ranging from 12V to 650V. We can expect to see both AC (alternating current) and DC (direct current) within these voltage ranges. Combining these variable voltages and currents with dozens of interconnected modules makes diagnosing and repairing these systems much more dependent on a healthy level of education 44 PTEN FEBRUARY 2022 www.VehicleServicePros.com * Snap-on VERUS Edge * Snap-on Pass-Thru Pro IV * Launch X-431 Pad II AE * Autel MaxiSYS Ultra * Cornwell and Snap-on multimeters & accessories * Snap-on Depinning Tool Set, various crimpers, Milwaukee Tool Cordless Soldering Ironhttp://www.VehicleServicePros.com
