A device called a current sensor monitors electric current flowing through a wire and produces a signal corresponding to that current. A digital output or an analogue voltage or current could both constitute the generated signal.
Current sensors for EVs are fundamental parts. They carry out two main functions. They aid in determining how much energy is consumed. Avoiding overcurrents is also part of the second duty. Therefore, one of the key components of a battery design is its current sensors.
Current transformers, or CTs, are devices that measure the current flowing through a wire by using the magnetic field to detect the current and produce a proportional output. Current sensors are another name for current transformers. With both AC and DC current, they are put to use.
The Global EV DC current sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
LEM announces a new current sensor for high-power EV traction inverters. High-power integrated traction inverters must, like all automotive components, combine excellent performance with being as tiny and light as possible in order to convert DC into AC and gather energy for the automobile.
In the cutthroat EV industry, distance and charging speed are essential factors. Compared to a traditional C-core sensor, the new HSTDR current sensor from LEM is significantly smaller and lighter, measuring only 29 mm by 21 mm by 12 mm and weighing only 27g. As a result, integrating it into inverter boxes with limited space is made significantly easier.
The sensor makes it possible for traction inverters to function as effectively as possible by combining high accuracy, accessibility, and the capacity to function in adverse conditions. The sensor has an operational temperature range of -40°C to +125°C and is resilient enough to withstand 10G of vibrations.
More accurate torque control is possible thanks to the HSTDR's superior immunity to external field and cross talk, constant behaviour across frequency, and minimal part-to-part phase shift dispersion. This is made possible by cutting-edge magnetic core technology and open loop Hall effect.
The sensor is suitable for 800V battery systems and ensures galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit). It allows EV manufacturers the choice of having different current measuring ranges â from 300 A to 1500 A â in the same container.
The only sensor for EV traction inverters, DC link, and 3-phase current measurement to incorporate an integrated busbar, starting with the previous HSNDR, fitting neatly into the smallest core aperture, was one way LEM's designers were able to decrease the footprint of the HSTDR.
The ability to use a core, busbar, and sensing element package that has been properly calibrated will provide EV producers and designers of automotive components the opportunity to drastically reduce the time it takes to produce their products.
