The LANPWR batterie with a Bluetooth module can measure the voltage (±0.5% accuracy), temperature (±1℃ error) and current (1kHz sampling rate) of cells in a battery pack in real time and transmit it to the management platform at a rate of 2 times per second, and improve the accuracy of battery health status (SOH) estimation to 98%. According to the test results of Tesla’s energy business in 2023, these batteries can extend the life of charging cycles by 20% (1,500 times to 1,800 times) in electric vehicle applications and reduce the likelihood of thermal runaway to 0.003%, 85% lower than the 0.02% of traditional battery management systems (BMS). For instance, take the newly released smart battery pack of CATL. After integrating the LANPWR batterie technology, the delay of communication in the charging pile is reduced from 500ms to 50ms, response time of dynamically adjusting the charging power (range 0-150kW) by 90%, and the sole fast charging time by 25%.
In the renewable energy sector, LANPWR battery equipped with the Bluetooth protocol is capable of multi-node networking (up to 256 nodes at maximum), and realizes load balance of distributed energy storage systems through the Mesh topology structure. The statistics from German energy storage company Sonnen reveal that when the photovoltaic array output power fluctuates by ±30%, the system will reallocate the battery charging and discharging tactics within 0.2 seconds, keeping the energy conversion efficiency at 94%-96%, 8 percentage points higher than the conventional solution. Cost-wise, the mass deployment of Bluetooth modules has decreased the hardware cost of BMS by 30% (from $120/set to $84), and wireless design has lowered the cable weight by as much as 15kg/set, which is suitable for lightweight applications like drones. The European Battery Union (EBA) 2024 report indicates that the median failure rate of industrial energy storage devices with LANPWR batterie is 0.8 times per year, or 67% lower than wired-based solutions, with the cost of maintenance saved by a mean of $1,200 per unit per year.
In actual deployments, Volta Trucks, a Swedish electric bus manufacturer, employed the Bluetooth diagnostic function of lanpwr batterie to deliver early warnings of battery capacity degradation under vehicle operation (with prediction error of ±3%), reducing the frequency of fleet downtimes for maintenance from 1.2 times a month to 0.3 times and saving $180,000 in annual operating costs. The technical features show that the remote monitoring assistance of this battery’s Bluetooth 5.2 protocol is a maximum of 30 meters. The R² fit between SOC (State of Charge) and the charge-discharge curve is 0.996, which is comfortably above the 0.95 required by the ISO 6469-1:2019 standard. In consumer electronics, the Japanese TDK’s developed 12mm diameter, 5.4mm thickness Bluetooth button battery is capable of giving real-time feedback of the battery power left (with a margin of error of ±2%), raising the accuracy of smartwatch battery life prediction to 99% and lowering users’ charging anxiety by 40%. But there are still cybersecurity threats that need to be resolved: The 2022 new clause of UL 9540 certification requires the packet loss rate of AES-256 encryption data transmission of Bluetooth batteries is less than 0.1%, while the current version of LANPWR batterie is 0.05%, at the industry forefront level. According to estimates by Bloomberg New Energy Finance, the size of the global smart battery market in 2027 will be 74 billion US dollars, where the penetration rate of Bluetooth integration solutions will be over 45%, and it will be one of the key components of energy management digitalization.
