Coreless current sensor achieves 2 μs response time for EV applications
Melexis unveils the MLX91235, a new current sensor that eliminates the need for a ferromagnetic core. The MLX91235 expands Melexis’ portfolio, enabling the measurement of larger currents flowing through external primary conductors like PCB traces and busbars. It supports automotive and alternative mobility applications like inverters, battery management systems (BMSs), and low-voltage DC-DC converters. Power […]
What are the types and uses of position and angle sensors in an EV?
Position and angle sensors are used in several electric vehicle (EV) components, including the traction motor and drivetrain, heating, ventilation, air-conditioning (HVAC) compressor, steer-by-wire, brake-by-wire, regenerative braking, accelerator position, active headlight aiming, active suspension systems, and more. This FAQ reviews some position and angle sensing technologies and how the use cases differ between internal combustion […]
How current sensing impacts electric vehicles: part 2
Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options, such as magnetoresistance and diamond quantum sensors. One of the significant issues in today’s electric vehicles (EVs) is the ongoing evolution of technology, with the standards evolving as well. In the 100+ years that […]
How can quantum sensors and quantum batteries improve electric vehicle operation?
In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using […]
Miniaturized MEMS pressure sensor incorporates proprietary tech for enhanced EV thermal management
Melexis has introduced the MLX90830, a miniaturized MEMS pressure sensor that incorporates the company’s patented TriphibianTM technology. The sensor is capable of measuring gas and liquid media from 2 to 70 bar. It is factory-calibrated to measure absolute pressure and provides a proportional analog output signal. The MLX90830 is designed to be integrated into the […]
