During daily charging, many new energy vehicle owners may have encountered the situation where the charging gun automatically disconnects when the battery is nearly full. What is the reason for this? Stay tuned for today’s article to gain a deeper understanding of the charging principles of new energy vehicles~ 01 SOC is about 98% to … Read more
☆Follow this public account to never miss an update☆ In electric vehicles, 40% of the cost comes from the battery, which acts as the “heart” providing the “blood-pumping function” for the electric vehicle. The performance and lifespan of the battery are crucial indicators of the electric vehicle’s performance. How can we monitor these indicators and … Read more
In this issue, we will briefly discuss Dynamic Power Management (DPM) in the NVDC Charger. Let’s quickly review the principles of NVDC: By adding a switch between the system and the battery, when the battery voltage Vbat<Vsys_min, the system voltage Vsys can be maintained at a fixed value through DC/DC conversion. Dynamic Power Management (DPM) … Read more
The performance and safety of lithium-ion batteries are closely related to their operating temperature range. Excessively high or low temperatures can lead to capacity degradation, increased internal resistance, and even catastrophic safety incidents such as thermal runaway. Therefore, establishing an efficient and reliable Thermal Management System (TMS) is crucial. The effective operation of this system … Read more

In 2025, the embedded talent market will show significant differentiation. Not all embedded engineers can command high salaries. The key lies in the choice of direction. Those who choose the wrong path may find their monthly salary hovering around 12,000 for three years. In contrast, those who select the right track, with the same work … Read more
“A fully charged battery brings joy, but a battery kept at full charge for a long time becomes waste.” As an editor with years of experience in the automotive media industry, I am Zhang Keji, and today I want to delve into a controversial technical topic—the real impact of keeping lithium iron phosphate (LFP) batteries … Read more
1. Why Choose SVR for SOC Prediction? SOC prediction is essentially a regression problem — predicting the remaining battery percentage based on features such as voltage, current, temperature, and time. Support Vector Regression (SVR) performs excellently in small sample, nonlinear problems, making it particularly suitable for batteries, which are influenced by multiple factors and have … Read more
