Archived video of a webinar hosted by Nuvoton Technology.
This article contains an archived video of a webinar hosted by Nuvoton Technology on June 21, 2024.
Lithium-ion batteries (LiBs) have seen increased use alongside the proliferation of mobile phones and smartphones, and are now widely adopted in high-capacity, multi-cell applications such as electric vehicles (BEVs) and energy storage systems. However, LiBs carry the risk of overheating and fire due to overcharging and over-discharging, making advanced monitoring and control technologies essential to ensure safety. Furthermore, with the growth of the BEV market, high-voltage technologies aimed at shortening charging times are also advancing, increasing the need for more accurate monitoring of battery status.
This video summarizes market trends and technological challenges surrounding secondary batteries, and explains the battery monitoring technologies being developed by Nuvoton Technology. In addition to the residual value assessment technology using AC impedance measurement that the company has proposed so far, it introduces voltage monitoring technology utilizing battery monitoring ICs and proprietary algorithms, as well as technology for estimating internal temperature from impedance changes within battery cells.
Furthermore, the document describes approaches that support improved safety during rapid charging by estimating the internal temperature of battery cells, as well as residual value assessment technologies to promote the reuse and Our Group's Purpose of lithium-ion batteries (LiBs). This content is recommended for engineers working on enhancing the functionality of battery management systems (BMS) and improving battery life and safety.
