Title: Accelerating Battery Management System Development for Nordic EV Supplier
Overview Box:
- Client: Tier 1 Automotive Supplier, Sweden
- Industry: Automotive / Electrification
- Service: Consulting & Resource Support
- Duration: 9 months
- Team Size: 2 Senior Hislanders
Challenge: A leading Nordic automotive supplier needed to accelerate development of their next-generation Battery Management System (BMS) for electric vehicles. Their internal team was stretched thin across multiple projects, and they needed experienced embedded systems engineers who could integrate seamlessly and deliver quickly. Time-to-market pressure was intense, with major OEM customers waiting for the new BMS technology.
Hisland’s Approach: We deployed two senior Hislanders with deep expertise in:
- Embedded C/C++ and real-time operating systems (RTOS)
- Automotive safety standards (ISO 26262 ASIL-D)
- Battery management algorithms and state-of-charge estimation
- Proactive problem-solving and cross-cultural communication
Our consultants didn’t just execute tasks – they became integral team members, participating in architecture discussions, mentoring junior engineers, and identifying risks before they became problems.
Solution Delivered:
- Week 1-2: Rapid onboarding and integration with existing team
- Month 1-3: Core BMS monitoring algorithms development
- Month 4-6: Safety-critical features implementation and validation
- Month 7-9: System integration, testing, and production release support
Key contributions:
- Developed state-of-charge (SOC) estimation algorithm with 98%+ accuracy
- Implemented cell balancing strategy reducing charge time by 15%
- Identified and resolved 15+ potential safety issues proactively
- Created comprehensive technical documentation
- Mentored 3 junior engineers, accelerating their capability development
Results: ✓ 3 months faster time-to-market than originally projected
✓ Zero critical bugs in production release
✓ 15% improved charging efficiency through optimized algorithms
✓ Client extended engagement for next-generation platform
✓ 2 junior engineers trained to take over after Hislanders transitioned
✓ €500K+ cost savings vs. hiring permanent senior engineers
Client Testimonial: “The Hislanders weren’t just consultants – they became part of our family. Their technical skills were excellent, but what really impressed us was their proactive mindset and ability to see the bigger picture. They identified issues we hadn’t even considered yet, and their mentorship of our junior team members created lasting value beyond the project.”
