various dimensions, as well as weight. The Pilot BT has the capabil- ity to test battery packs up to 41.33 x 34.05 in. (1,050 x 865 mm) and weighing up to 220.5 lb (100 kg). The third consideration is sys-


tem reliability. The production of batteries and their individual cells and “packs” could almost be consid- ered an autonomous operation. Ideally, the OEM or battery manu- facturer would like to pour a little bit of lithium, a pinch of iron, a cup of “secret sauce” into the hopper in the front end, and out comes a battery


cell. This is an oversimplification, but the only way to get close to this is with highly reliable production equipment, where limited operator intervention is required. Achieving this in a test solution


is problematic, since batteries have a larger buildup of tolerances than cir- cuit card assemblies — the tolerance from the individual placement of the batteries in the pack, from the bat- teries to the terminal plates, from the pallet or carrier to the battery pack to be tested, and so on. In this scenario, the ability to reliably con- tact individual cells for testing is


essential. This signifies that the tester


must have the capability to check mul- tiple fiducials to ensure the utmost targeting accuracy, as well as the means to assess very quickly, precise- ly and in real time, any unusual toler- ances of the packs and to make adjust- ments on the fly. The presence of laser scanners, high-precision cameras and dedicated software, such as those included in the Pilot BT, are funda- mental to be able to eliminate guess- work and manual adjustments for tol- erances, and move to a completely automated test process.


A standard, automated test solu-


tion can offer a superior alternative to the home-grown remedies that many manufacturers have used until now, with a high overall equipment effec- tiveness (OEE) rating and facilitated maintenance, due to robust self-test diagnostics and standard parts. By focusing on the key concepts of speed, configurability and reliability, new test solutions, such as the Pilot BT, allow OEMs and battery producers to concentrate on other facets of their own businesses, be it building cars or building batteries. With estimates for 2020 battery


market ranging from $25 to $60 bil- lion, it is certainly prudent to keep an eye on test solutions for this mar- ket. The early adopters are the win- ners here. Barring any negative political climate or cost of oil, new breakthroughs in battery technology are on the horizon, though some tur- moil in the EV market will still exist. Most people would agree that the EV market is here to stay. Contact: Seica, Inc., 110 Avco

Eaton Expands Automotive Grade Magnetics


Pleasanton, CA — Eaton has launched its automotive-grade HMC - 1AV2 product line of high-current power inductors, designed for the transportation market to address increased power conversion and fil- tering requirements. The HCM1AV2 is tested beyond AEC-Q200 Grade 1 requirements for added reliability and confidence desired by most auto- motive engineers. The robust molded construction


makes HCM1AV2 suitable for high vibration and shock. HCM1AV2 offers 10 standard inductor sizes and PCB footprints from 0.2 to 0.9 in. (4 to 22 mm), high current capability up to 100A, low DCR, low EMI, high voltage isolation, low core loss, soft saturation (roll-off), and performance stability across its operating temper- ature range. The advanced construction and


high-grade materials used in HCM1AV2 inductors are designed to withstand the effects of high-temper- ature, high-humidity environments in many automotive electronic sys- tems. Eaton’s solution offers high current carrying capacity, high power density, low core losses and magnetic shielding to reduce EMI effects to other devices in the auto- motive engine compartment.
