Fleet Energy Management in Battery Systems For LEVs

Introduction

As cities transition to low-emission transport systems, light electric vehicles (LEVs) such as cargo bikes, scooters, tuk-tuks, and microvans are becoming increasingly central to urban mobility strategies. A critical enabler of this shift is the evolution of compact, lightweight battery systems tailored to the unique demands of LEVs, where range, weight, cost, and charging time must be balanced within tight spatial and regulatory constraints.

Electric cargo bikes, for example, rely on mid-capacity lithium-ion packs with fast-swapping capability and integrated Battery Management Systems (BMS) that monitor thermal conditions, voltage stability, and charge cycles. Meanwhile, last-mile logistics providers are adopting modular battery packs and multi-vehicle charging stations to streamline operations across large fleets and reduce turnaround time.

Battery technology innovation is about system integration, charging ecosystems, and data-driven maintenance protocols. In March 2025, Tern unveiled its new GSD electric cargo bike with a 6061 aluminium frame and upgraded dual-battery system for extended range. The ability to remotely monitor battery health, anticipate degradation, and trigger proactive servicing is critical for uptime in commercial operations. In addition, smart BMS platforms are now capable of sharing diagnostics with fleet management software, enabling predictive analytics, optimizing energy distribution, and minimizing downtime.

The emergence of interoperable battery platforms is also gaining traction, with several OEMs and startups pushing for standardized battery formats that can be shared across multiple vehicle types, from scooters to cargo trikes. This interoperability is vital for the scalability of urban LEV fleets, particularly in dense delivery networks where flexibility and fast replacement are operational priorities.

Small Format Batteries Are Powering a Big Mobility Shift

The growing deployment of LEVs has triggered demand for low-voltage, compact batteries optimized for safety, cycle life, and charging flexibility. Lithium Iron Phosphate (LFP) chemistries are emerging as a popular choice for electric cargo bikes due to their thermal stability and long lifecycle. In contrast, some higher-end applications are adopting NMC (Nickel Manganese Cobalt) cells for extended range and lower weight.

Energy density is being balanced with cost and robustness, especially for commercial use in harsh environments. Swappable batteries and integrated IoT/BMS systems now enable fleet operators to monitor real-time battery health, plan replacements, and reduce downtime.

OEMs are increasingly designing vehicle-integrated battery compartments, creating compatibility standards for multi-use across cargo bikes, delivery scooters, and small EVs. Regulatory pressure on recycling and second-life use is also shaping how battery packs are sourced, maintained, and retired.

Finally, advancements in battery safety, including thermal management systems, waterproof casings, and passive cooling technologies, are making LEVs more reliable in varied urban climates. Combined with growing policy support for localized battery production and end-of-life recycling, these developments are positioning LEV battery systems as a foundational pillar in the decarbonization of short-range urban transport.
