Why BMS Demands More Stable Current Sensing for Lithium DC Power Systems

DC backup power systems for substations, data centers and renewable energy sites are gradually replacing traditional lead-acid batteries with lithium iron phosphate (LFP) batteries. This upgrade is far more than a simple battery replacement, as it fundamentally transforms the role of current sensing. Lead-acid systems rely on voltage and floating charge status to judge battery conditions. Current sensors only work for basic data display and fault alerts, with loose standards for long-term precision. However, LFP cells feature a flat voltage plateau across most of their SOC range, making voltage alone unable to accurately reflect remaining capacity. Lithium BMS adopts a combined SOC estimation algorithm built on coulomb counting, where stable current sampling is the core foundation. Minor long-term measurement errors like zero drift and temperature drift will accumulate continuously and severely distort SOC calculation, disrupting charge-discharge control and battery safety protection. Lithium DC power panels adopt two separate current detection positions with differentiated sensor selections. The battery side sensor supports core BMS functions including SOC calculation, so high-precision closed-loop Hall sensors (such as CHIPSENSE CR1A series) are preferred for their low drift and excellent long-term stability. The DC bus side sensor monitors overall system load and abnormal current, where cost-effective open-loop Hall sensors (like HS3V series) can meet regular monitoring demands. In short, current sensing has shifted from a simple monitoring tool in lead-acid systems to a critical control data source for lithium BMS. As smart grids and new energy industries expand, DC power systems will keep raising requirements for current sensors in precision, long-term stability and control integration.

GreenX Metals: 2026 Fieldwork Underway at Eleonore North gold/tungsten/antimony exploration project in Greenland. Potential source of rare critical minerals for EU market.

22 July 2026. GreenX Metals Limited (ASX:GRX, LSE:GRX, GPW:GRX, Germany-FSE:A3C9JR) (GreenX or the Company) is pleased to announce that fieldwork has commenced at its Eleonore North project in East Greenland (Eleonore North or Project). The exploration program is targeting gold (Au), tungsten (W), and antimony (Sb).

GreenX’s Chief Executive Officer, Mr Ben Stoikovich, commented: “Greenland is an exciting frontier for GreenX, and this program advances a portfolio of gold, tungsten and antimony targets that has seen very little modern exploration.

Tungsten and antimony are critical raw materials for both the European Union and the United States, and Eleonore North gives us high-grade occurrences of both in a stable Western jurisdiction at a time when supply is heavily concentrated in China. Importantly, the tungsten and antimony mineralisation has a surface expression, which allows us to make rapid progress in expanding the known mineralisation and generating additional targets.

This year we are in the field to advance our existing prospects, including the Noa Pluton gold-antimony target and the North and South Margeries deposits. At the same time, our growing understanding of intrusion-related gold systems in the region has enabled us to identify a number of new targets.’’
