Testing Automotive Electrical Systems

Using the latest in testing equipment and techniques, Primetime Testing Laboratory can effectively test most aspects of a vehicle’s electronics or electrical system within ISO 7637-2, ISO 7637-3, and ISO 16750-2. We know that every project is different and will take the time to fill you in on everything you need to know about the process, the paperwork, and the results.

Our Common Electrical Tests We Perform Daily

• Continuous monitoring up to 300 V / 100 A
• Crank pulses – This test analyzes the capability of a vehicle to start and stop under both extreme temperature and voltage conditions. Crank Pulse testing verifies the functional capability and durability of components that are subjected to crank pulses that are generated by conventional starts and by the stop and start system.
• Ground/power offset – Large currents in distributed systems can cause local ground references to differ significantly. Using simulation, we can help spot and resolve problems to ensure system reliability.
• Insulation resistance – Measures the total resistance between any two points separated by electrical insulation. This helps determine how effective the dielectric insulation is in resisting the flow of electrical current. The results are useful for checking the quality of the insulation, not only for when a product is first manufactured but also over time as it is being used.
• Jumpstart
• Overvoltage – The most popular method of general conditioning and integrity assessment in the power, industrial and domestic markets, overvoltage testing is critical to the long-term health of any electrical system.
• Overload testing – An overload occurs when the current running through an electrical circuit exceeds safe levels usually due to an unexpected power surge on the circuit.
• Parasitic current / IOD – A parasitic current drain is when an on-board electrical device draws electric current from the battery when the vehicle’s ignition key is turned off. While all vehicles do this, it is usually a very small draw. An electrical short in the vehicle can cause it to draw more than its normal load, causing a large drain on the battery.
• Power supply interruptions – With short interruptions or voltage dips and voltage variations, we can help evaluate the immunity of electrical and electronic equipment when subjected to these conditions.
• Resistance measurements between 1 mΩ and 1 GΩ – Resistance Measurement is calculated by measuring the current and voltage applied to the circuit. Proper resistance in the circuitry of electronic devices is necessary as it may cause devices to malfunction.
• Short circuit testing
• Superimposed voltage
