A closer look at current sensors in EVs
Pretty much every electronic circuit that handles significant power utilizes some means of measuring current, whether to simply protect against overload or because it is a basic functional requirement. In this article we’ll cover some of the more common devices and circuit techniques for measuring current in the major subsystems of an EV, including when… Read more »
ACEINNA expands AMR-based current sensors to support 3.3 volt applications
ACEINNA, a Massachusetts sensor manufacturer, has announced that its MCx1101 family of current sensors now supports 3.3 volt applications commonly found in EV charging stations, inverters, and motor controls. The MCx1101 sensors are fully integrated, bi-directional current sensors. ACEINNA says they offer much higher DC accuracy and dynamic range compared with other solutions. For example,… Read more »
New concept for current and voltage sensors could enable simpler battery packs
Engineers at Germany’s Ruhr-Universität Bochum (RUB) have developed a new concept for current and voltage sensors that may be particularly relevant to EV batteries. Battery monitoring typically requires as many current and voltage sensors as there are individual cells. RUB’s system uses only one of each, regardless of the number of cells. Moreover, both sensors… Read more »
3D smart sensors for inline EV battery inspection
Sponsored by LMI. The increase in demand for EV Batteries has already permanently transformed the car manufacturing landscape, with almost all major automotive companies now operating electric vehicle production lines. While electric vehicles do have less moving parts than their internal combustion engine (ICE) counterparts, manufacturing them is still extremely complex. From stators and rotors,… Read more »
