Today’s electric vehicles operate at voltages approaching 1000 Vdc, engineers need to monitor and record those voltages during tests. B+K Precision has added the D18-HVM4 high-voltage, 4-channel input module to its DAS1800 modular … [Read more...]
Research shows improvements for fast-charging of Li-ion batteries
Researchers at Chung-Ang University used high-concentration electrolytes to improve safety and prevent cell swelling caused by lithium plating. To achieve a greater adaption of electric vehicles, the automotive industry needs fast-charging … [Read more...]
Trigger alerts when Li-ion batteries get too hot
TTape from Littelfuse, a set of temperature-triggered switches, raises a bit that indicates hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their … [Read more...]
A simple way to monitor Li-ion battery-pack temperature
A set of temperature-triggered switches alerts you to hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. So, it’s important to monitor their temperature and act before damage occurs. You can … [Read more...]
Breakout module measures EV AC charging voltage and current
The HV Breakout Module 3.1 OBC from CSM provides access to AC mains cables for measuring single-phase to three-phase current, voltage, and power. EVs need many electrical measurements and so do charging stations. Getting access to AC mains or … [Read more...]
EV battery tests involve lots of power
In a video, EE World spoke with a power-supply applications engineer about why RV batteries use such high voltages and how to test them. Batteries are perhaps the most expensive component of an electric vehicle. Typically producing 800 V to 900 V, … [Read more...]
