On May 13, a tech firm released the SE8518 series of four BMS-focused shunt resistors, targeting critical industry challenges: SE8518-10: Micron-level tin plating withstands 2,000-hour salt spray testing. SE8518-02/12: Triple-pin design enables simultaneous voltage, temperature, and current sensing. SE8518-03/13: M3 threaded holes boost installation efficiency by 60%, ideal for battery-swap systems.
Compact 800×800mm Shunt Resistor Debuts, Solving Precision Challenges in EV Battery Management
As the global EV industry enters a critical phase of battery management system (BMS) upgrades, a tech company unveiled the SEFL-100A-100mV-01 fixed-value shunt resistor on August 1. Measuring 800×800mm, this brass-based component achieves a 100mV voltage drop at 100A current, utilizing high-purity manganin alloy for ±0.5% accuracy across -40°C to 125°C. Its 30% smaller footprint enables direct integration into battery modules.
