Global Solutions Battery System — Built for Real Routes

We are developing swappable, modular 12V battery packs with air cooling and cloud-based control, designed to help fleets maximise battery utility and lifespan, keeping vehicles productive and earning.

Packs charge off-vehicle while extending their usable life through managed charging protcols and detection of sub-optimal performance.

The prototypes and their proven outcomes, detailed thermal and structural analysis, casing evaluation, swap and charging workflow development, factory readiness in Kathmandu, establishment of pilot routes, and the performance scoreboard all guide our scaling strategy.

The Problem & Insight

Our target use cases are dominated by known, repeatable routes served by rickshaws/tempos, vehicles reliant on fixed batteries that must charge slowly overnight via the grid.

In many developing regions, unreliable grids cause slow or incomplete charging, leading to shortened battery lifespans and increased fleet downtime.

By deploying swappable battery packs charged off-grid at solar stations, we eliminate dependency on unstable grids while ensuring optimal charging profiles that extend battery life and reliability.

These battery packs incorporate integrated air cooling, enabling effective thermal management even during rapid charging, maximising operational efficiency and fleet availability.

Day-One Principles – Designed Around Real People and Real Needs

People First: Each battery pack weighs under 15 kilograms, enabling both male and female drivers to easily and safely swap battery sets autonomously, driving operational efficiency across diverse workforces.

Decoupled Charging: Swappable battery packs mean vehicles never need to wait for charging, allowing continuous revenue generation and maximising fleet productivity. Vehicles don’t have to wait to charge, which means they can continue earning revenue.

Comprehensive Instrumentation: Every battery pack records critical data – life cycle metrics, temperature, state of charge – feeding into AI-driven management systems that predict maintenance needs, optimise performance, and underpin robust financial models and payment workflows..

Prototype Journey — What each stage proved

Prototype 1 (P1)

Introduced a keyed, tapered geometry to ensure precise insertion, combined with a serviceable enclosure featuring a removable top housing and secure screw pattern.

The design incorporated a Battery Management System (BMS) and state-of-charge indicator mounted on a removable carrier, along with a prismatic cell block fixed on a stable base plate.

Outcome: Demonstrated safe, reliable insertion; fast and easy access to critical components like BMS and busbars; and established a clear pathway for rotation and repair.

Prototype 2 (P2)

Enhanced the system with a rail interface and integrated a lattice frame inside the pack. The exploded architecture clarified manufacturability and streamlined the assembly process.

Outcome: Achieved cleaner integration with cradle and rails, creating space for necessary structural and thermal components.

Prototype 3 (P3)

Focused on evolving casing design to align perfectly with cradle and swap station requirements, preparing the module for rigorous field integration and durability testing.

Prototype 4 (P4)

Prototype 4

Outcome: Confirmed enclosure maturity and interface readiness for pilot deployment and real-world use.

Cooling Findings – Validated Thermal Performance

Computational Fluid Dynamics (CFD) analysis shows that introducing an airflow of 28 cubic feet per minute (CFM) through a 10 mm gap between modules inside the enclosure significantly reduces internal temperatures compared to no airflow.

The fan power estimated for this configuration during studies was approximately 1.5 kilowatts, demonstrating an effective balance of cooling performance and energy consumption.

Casing Static Analysis – Informed Design Improvements

We evaluated the structural integrity of the battery pack casing against relevant European standards to ensure alignment with crash-worthiness certification requirements.

Study parameters included a PA6-CF casing restrained at the base mounting slot, subjected to a 50g (~6 kN) distributed internal load, with contact points at the casing-to-lid interface.

Results identified peak stress concentrations at the lid region and near the base mounting slot that exceeded material yield limits.

To address this, design modifications include adding stress-relief features, increasing the base thickness, and/or redistributing the load through the supporting cradle structure, enhancing overall durability and compliance.

True Modularity & the Cradle

A standardized cradle and rail system accommodates both current battery modules and future form factors, ensuring seamless compatibility as next-generation packs are developed.

This consistent mechanical framework supports both vehicle mounts and swap stations, enabling rapid integration and straightforward upgrades across the fleet infrastructure.

Vehicle Targets & Use Cases

Our initial integrations focus on two key vehicle types: the electric rickshaw (4–6 seat) and the electric Safa tempo (12–15 seat).

Both vehicle categories will use our swappable battery pack system, configured as six battery packs for the rickshaw and twelve packs for the tempo. These battery packs are strategically installed beneath the bench seats to preserve the vehicle’s cargo space, maintaining operational utility while upgrading energy capacity.

Charging Workflow — Balancing Grid and Solar for Maximum Uptime

Currently, vehicles rely on slow overnight charging when the grid is available. Our proposed hybrid model combines this with daytime charging using photovoltaic (PV) solar power, reducing dependency on the grid and increasing operational resilience.

Overnight grid charging occurs at a gentle rate below 0.2C, preserving battery life.

During the day, battery modules rapidly recharge at rates exceeding 1.0C with turnaround times of just 30 to 60 minutes at solar-powered stations, keeping vehicles moving while energy refills off-board.

Factory Enablement — Kathmandu

On site, critical infrastructure is in place including clearly zoned and waterproofed areas, installation of lithium-class fire extinguishers, and comprehensive safety signage. A demonstration cradle has been constructed, while dust- and moisture-controlled rooms and ramp upgrades are actively progressing.

These foundational elements are essential to support local assembly, ongoing repair capabilities, and comprehensive staff training programs—ensuring the factory is prepared for efficient, safe, and scalable production.

Pilots & Routes – Nepal

Our pilot sites are strategically located in Dhading and Bardia, two socially underdeveloped regions chosen to maximise benefits for marginalised and remote communities. These sites feature defined, repeatable routes well-suited to modular energy applications but present distinct operational challenges, including varied terrain and environmental conditions.

Dhading’s landscape ranges from lowland hills to high mountains, including alpine zones, while Bardia encompasses subtropical plains and dense forested areas including protected national parks. This diversity offers a robust testbed for our technology.

A photovoltaic (PV) study has been completed, with solar installations scheduled to integrate clean energy generation with sustainable mobility.

Together, these pilot sites create a valuable and diverse data pipeline that informs ongoing development and scaling strategies.

Telemetry, Payments & Digital Twin

Each battery pack collects detailed telemetry data, which is downloaded onto the charging cradle station. This module-level data is then securely uploaded to a cloud platform that integrates payment processing, fleet analytics, and a sophisticated digital twin.

The digital twin creates a virtual replica of each battery module, enabling predictive maintenance scheduling that minimises downtime and extends asset life through proactive interventions.

Performance insights are shared with finance teams, empowering accurate cost modelling for battery rental and enabling seamless energy-as-a-service business models.
