Nuvoton Technology's Innovative BM-ICs for Industrial Applications
Nuvoton Technology Corporation Japan (NTCJ) is set to introduce groundbreaking industrial battery monitoring integrated circuits (BM-ICs) designed for 48V batteries. These new products, named "KA49701A" and "KA49702A," are scheduled to enter mass production soon.
Enhanced Safety Features in Battery System Design
The newly developed BM-ICs are specially engineered to enhance the safety of battery systems, ensuring streamlined and secure system implementation. These ICs play a crucial role in maintaining safe operation during instances like overcharging or over-discharging. NTCJ's innovative designs are built to detect and respond to circuit failures, integrating diagnostic and fail-safe functions that enhance overall battery management system (BMS) safety.
Reductions in System Cost and Size
By ensuring the primary circuits involved in cell voltage measurements are equipped with advanced diagnostic functions, Nuvoton mitigates the necessity for external protection circuits that typically require additional board space and increase costs. This balance of safety and cost efficiency makes the new BM-IC models attractive solutions for various industrial applications.
Unmatched Voltage Measurement Accuracy
NTCJ has achieved industry-leading voltage measurement accuracy of +/-2.9mV, a significant improvement thanks to the reduction of noise on the 16-bit AD converter and the inclusion of a digital filter. This precision allows users to maximize the battery's capacity and ensures reliable operation over a broad temperature range.
Performance in Extreme Conditions
The BM-ICs are particularly well-suited for stationary battery systems that adhere to strict standards, providing accurate measurements even in extreme temperatures. This reliability ensures that battery systems remain operational under varying environmental conditions, making them essential for many industrial applications.
Optimized Power Consumption for Extended Battery Life
Another notable feature of the KA49701A and KA49702A is their remarkably low power consumption. By decreasing the time required for cell voltage measurement, the operating current has been reduced to an impressive 260 microamperes, less than one-tenth of previous models. This significant cut in power usage translates to extended operational times for battery systems.
Minimized Self-Discharge Rates
In addition, NNCJ's optimization in circuit design reduces the shutdown current consumption to less than 0.1 microamperes. This minimizes self-discharge, preventing deterioration from over-discharge during long-distance transportation or extended storage of lithium-ion batteries (LIBs).
