Logistics & Analysis
Complete pack collection and full diagnostic telemetry readouts. We analyze BMS error codes, state of health (SOH), and internal resistance.
Commercial transit operators and electric fleet managers face substantial capital expenditure when high-voltage Energy Storage Systems (ESS) reach degraded performance or OEM end-of-life status. Altertek provides certified, precision engineering solutions designed to diagnose, recondition, and restore commercial vehicle ESS battery packs at a fraction of full replacement cost.
Utilizing state-of-the-art diagnostic platforms and cell-balancing hardware, our UK-based team pinpoints specific module failures and capacity imbalances. Rather than scrapping expensive energy storage units prematurely, our proprietary conditioning workflows extend operational lifespan by years while maintaining rigorous safety standards.
Every commercial vehicle battery pack undergoes a multi-point engineering review to guarantee electrical integrity, thermal stability, and maximum energy density recovery.
Complete pack collection and full diagnostic telemetry readouts. We analyze BMS error codes, state of health (SOH), and internal resistance.
Individual module teardown and Automated Cell-Level Analysis to isolate weak, degraded, or out-of-balance cells within the ESS enclosure.
Precision cell reconditioning, micro-balancing, and targeted replacement of degraded sub-assemblies using OEM-compliant components.
Rigorous full-load charge/discharge cycle testing, insulation testing, and safety certification prior to return to service.
Altertek has partnered with major UK bus transit operators to solve chronic battery degradation in Volvo B5LH hybrid fleets. When OEM dealer networks recommend complete ESS disposal and expensive replacement units, our engineering team offers a proven technical alternative.
Our custom-engineered testing rigs allow direct interfacing with the Volvo B5LH ESS architecture. We determine whether individual modules require replacement or if the pack can be fully restored through active cell-rebalancing and conditioning. In the majority of cases, full operational performance is restored without replacing the entire battery assembly—saving transport operators tens of thousands of pounds per vehicle.
Engineered for high-voltage commercial transit systems, heavy duty e-trucks, and hybrid bus architectures.
