What is ISO pulse?
What is ISO pulse?
ISO Pulse Immunity The test intention is the demonstration of the immunity of the equipment when subjected to coupled fast transient disturbances, such as those caused by switching of the ignition, power circuits, control devices, etc. Pulse 1 ISO 7637-1.
What is ISO 7637 2?
ISO 7637-2:2011 specifies test methods and procedures to ensure the compatibility to conducted electrical transients of equipment installed on passenger cars and commercial vehicles fitted with 12 V or 24 V electrical systems. It describes bench tests for both the injection and measurement of transients.
What is Ri in load dump test?
The amount of energy dumped to the load depends on the internal resistance (Ri) of the source, as shown in Figure 2. Figure 3. Output voltage of an alternator during a load-dump event showing nominal battery voltage (VB).
What Cispr 25?
CISPR 25:2016 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2 500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers and devices.
What is SAE J1113?
SAE J1113 specifies test methods and procedures for the testing of electromagnetic immunity of electronic components for passenger cars and commercial vehicles.
What is lv124?

What is LV123?
∕ Definition: ∕ LV123 is a harmonized document of test requirements of all German OEMs: ∕ Audi, BMW, Daimler, Porsche and VW. ∕ Advantages: ∕ Systematic approach and transparent definition of test parameter.
What is load dump voltage?
A load dump occurs when the load to which a generator is delivering current is abruptly disconnected. In automotive electronics, this applies to disconnecting a battery while it is being charged by the alternator. It can be “as high as 120 V and may take up to 400 ms to decay”.
How does a dump load work?
The dump load operates with a diversion charge controller and is much like the overflow on a bath tub. The bath tub is the battery bank and the wind turbine is a tap. The tap (wind turbine) continuously fills the bath with water (charge) until the level of the water reaches the level of the over-flow hole (dump load).
