Problem
Many modern electronic devices rely on generic battery management systems that provide coarse voltage and current monitoring, limited protection logic, and fixed charging profiles. This lack of high‑resolution sensing and adaptable control hampers battery life, safety, and the ability to leverage emerging battery chemistries or on‑device AI workloads.
Solution
Overlord Labs delivers a Battery Management System (BMS) integrated circuit that combines high‑resolution analog front‑end sensing with an embedded RISC‑V core for on‑chip firmware execution. The platform runs physics‑based electrochemical models directly on the silicon, producing accurate state‑of‑charge (SOC) and state‑of‑health (SOH) estimates without requiring an external microcontroller. OEMs can program custom charging curves, thermal limits, and power‑delivery policies using their own firmware, which can be updated over‑the‑air. Built‑in security primitives authenticate the cell and protect firmware integrity, while telemetry streams real‑time diagnostics to host systems for rapid iteration. The solution is engineered for integration into next‑generation devices that demand precise battery intelligence and flexible compute resources.
Target Audience
The primary customers are OEMs developing consumer electronics, wearables, IoT devices, and automotive subsystems that require advanced battery intelligence and customizable power management. Engineers seeking a programmable BMS solution for next‑generation battery chemistries and AI‑enabled hardware will benefit most.
