The EMC Shop stocks automotive voltage drop simulators to test components to be used in electric vehicles (as well as gas-powered). Meet ISO 7637-2 and other industry standards as well as manufacturer standards or use software to customize or replicate voltage dropouts that you want to expose your device to.
Voltage Drop Simulation test setup
Most of our customers will simply place the voltage drop simulator on a bench, ground the chassis, and be off and rolling. There are diagrams avaialble that specify spacing, placement, etc... We have found that in most cases, these aren't detrimental unless striving for full compliance.

Be sure the generator and external coupling devices are well grounded. Start testing at lower voltage levels to observe how your DUT responds as well as surrounding equipment in your test area. Your test setup may require you to move equipment and/or isolate your test area a bit more.
