Bespoke BMS Engineering for High-Reliability OEM Systems

At Altertek, all custom Battery Management Systems (BMS) are designed, programmed, and validated in-house by our team of senior electronic and software engineers in the United Kingdom. With over 15 years of practical experience across complex battery chemistry profiles—including LFP (Lithium Iron Phosphate), NMC (Nickel Manganese Cobalt), and LTO (Lithium Titanate Oxide)—we engineer tailored BMS platforms for mission-critical operations.

Our comprehensive electronics design capability encompasses every phase of development: from high-level system topology and schematic creation, to multi-layer PCB hardware prototyping, safety-critical embedded firmware design, and full compliance verification.

Altertek BMS Consultation and Engineering Specification Review

Phase 01 · Engineering Consultation

Technical Consultation & System Requirements Specification

The foundation of every high-performing battery management system is a deep understanding of operational envelope constraints. Battery technology evolves rapidly, requiring precise alignment on cell chemistry parameters, discharge kinetics, peak currents, thermal management limits, and communications protocols.

At project initiation, our engineering team collaborates closely with your technical directors to produce an agreed Requirement Specification document. This document acts as the definitive benchmark throughout hardware prototyping, firmware coding, and production line QA, ensuring first-time design validation.

Custom Low Voltage Battery Management System Hardware Circuitry

Phase 02 · Hardware & Firmware Design

Low Voltage to High Voltage BMS Circuit Architecture

Our senior design team brings extensive experience in developing both centralized low-voltage (12V to 48V) BMS units and high-voltage distributed architecture systems up to 800V+. We engineer bespoke PCB hardware optimized for tight physical envelopes, high shock/vibration resistance, and electromagnetic compatibility (EMC).

Operating under our ISO 9001:2015 certified design framework, we deliver SIL (Safety Integrity Level) compliant hardware and firmware implementations. For automotive, e-mobility, and commercial EV clients, our designs strictly adhere to ISO 26262 functional safety standards.

Automated BMS Verification Testing and Validation in UK Facility

Phase 03 · Quality Assurance

ISO 9001:2015 Verification & Validation Protocol

Reliability under extreme operating conditions is paramount for overseas procurement teams. Every custom BMS undergoes rigorous multi-stage testing prior to mass production clearance.

Verification plans are executed to validate hardware performance against sub-specification criteria, followed by system validation using Hardware-in-the-Loop (HIL) testing and live-cell cycling setups. Clients are provided with complete compliance documentation and are invited to witness validation testing either on-site at our UK lab or via secure live-stream sessions.
