Carrying out the meausurement
The automotive world is changing. Not only through the electrification of the combustion engine to a hybrid powertrain or a fully electrified powertrain in BEVs or FCEVs. Safety, handling, and comfort features are becoming increasingly numerous and complex, as are the variety of electrical systems and the number of consumers and control units in the vehicle. Safety functions are becoming more active and support the driver in ensuring safe operation, which leads to greater importance being placed on the availability of electrical energy for electrical systems. The battery management system must cope with different charging and load conditions in a variety of environments. These could be warm, cold, humid, or dry. Regardless of which type of vehicle the driver chooses, fuel consumption or battery capacity is always influenced by power consumption. In times of increasing requirements for exhaust emissions and range anxiety, manufacturers of passenger cars, trucks, and public transport vehicles must ensure full functionality under all conditions with minimal and demand-oriented consumption.
In view of the current situation, the following question arises as a logical conclusion: How can stability be ensured and the overall performance of the electrical system be increased? Answer: By measuring the power consumption of all consumers in the vehicle, including the electrical consumers in the low-voltage electrical system. This power consumption is measured by the HP-PROBE. The current and voltage are measured at an electrical potential (in the automotive sector, this is the vehicle ground), and their effect on overall consumption is determined.
Evaluation
KLARIC measuring devices provide solutions for the challenges posed by the increasing electrification of automobiles and deliver fast and precise results. With modular measuring solutions for every approach, the possibilities for determining the consumption of the entire circuit and individual components in the electrical system are wide-ranging and tailored to the needs of engineers. Typical applications include measuring quiescent, operating, and peak currents in the electrical systems of cars and trucks, e.g., in batteries, fuse boxes, heaters, and active chassis. The solutions, which are based on highly accurate results, are also designed for rapid application and are valued worldwide.
