Hybrid Battery System &
Charging Management System

A power-management invention from Amigas Green Tech combining a swappable primary pack, a fixed secondary pack, and a cloud-managed swap ecosystem — built to remove range anxiety, long charging waits, and infrastructure friction from electric vehicles.

Inventor: Keshav Gupta Conceived: Aug 2025 Status: Prototype working
Field of invention

EV power management — built for short trips and long journeys

The invention sits within the field of electric vehicles, and specifically a power-management system designed for efficient, seamless operation over both short and long distances. It introduces a hybrid battery architecture — a combination of fixed and swappable units — that switches dynamically based on the vehicle's operating requirements.

The goal is to address the core friction points slowing EV adoption today: range limitations, long charging waits, sparse and inconsistent charging infrastructure, and the operational inefficiencies that follow.

Why this is needed

Major issues with electric vehicles today

EVs are emerging as a sustainable alternative to fuel-based transport, but adoption is held back by a stack of overlapping problems across the vehicle, the network, and the grid.

  • Limited driving range

    Shorter usable range vs ICE vehicles makes long trips less convenient and triggers range anxiety.

  • Thermal management

    Battery cells are temperature sensitive — overheating reduces efficiency and can risk thermal runaway.

  • Battery weight & size

    Heavy, bulky packs reduce vehicle efficiency and restrict design flexibility.

  • Extreme weather drop

    EV performance degrades in extreme cold or heat — users notice reduced range and slower charging.

  • Sparse infrastructure

    Charging stations are unevenly distributed, often concentrated in urban hubs only.

  • Long charging time

    Charging takes far longer than refuelling, causing downtime and disrupting trip planning.

  • Charger compatibility

    Multiple standards and connectors create friction across manufacturers and stations.

  • High initial cost

    Upfront price keeps EVs out of reach for many middle-class buyers.

  • Grid & peak load stress

    Simultaneous charging can destabilise the grid and demand expensive infrastructure upgrades.

  • Renewable integration gap

    Aligning EV charging with solar and wind generation remains an evolving challenge.

Our invention

Three systems, working as one

The Hybrid Battery System and Charging Management System is built from three tightly integrated layers — together they remove range anxiety, eliminate long waits, and bring every stakeholder onto a single accountable platform.

Hybrid Battery System Pillar 1

Hybrid Battery System

Technical aspects

Each EV carries two complementary battery units — a swappable primary pack and a fixed secondary pack. The fixed pack is chargeable via every standard method (home, smart and fast chargers, public stations). The swappable pack uses modular 3 kWh / 4 kWh / 5 kWh blocks fitted with a liquid-cooled enclosure for safety and longevity.

Working process

The vehicle draws energy from the primary (swappable) pack first. Once the primary pack drops to ~10% remaining (90% consumed), the system seamlessly transitions to the secondary (fixed) pack so the journey continues uninterrupted.

  • Modular 3 / 4 / 5 kWh swap blocks
  • Liquid-cooled swap cases
Intelligent Charging System Pillar 2

Intelligent Charging System

Technical aspects

A purpose-built swap architecture for the modular 3 / 4 / 5 kWh packs, linked to a centralised server for live monitoring of battery inventory at every station. An automated battery-health engine evaluates each pack against defined safety and performance criteria; non-compliant packs are auto-locked and flagged defective.

Working process

When primary charge drops below 30%, or once the vehicle has moved to the secondary pack, the user opens the app, locates the nearest station with confirmed available batteries, drives in and completes a verified swap in under five minutes.

  • Real-time station & inventory view
  • Automated health scoring
  • Sub-5-minute verified swap
Charging & Battery Management System Pillar 3

Charging & Battery Management System

Technical aspects

A cloud-based application that ties every stakeholder — charging stations, battery manufacturers, sellers, service centres, vehicle OEMs, and customers — into a single registered ecosystem. Vehicle and battery warranty data is captured at the point of sale and tracked through every swap cycle.

Working process

During the warranty period (e.g. five years), the customer can perform unlimited verified swaps. Returned packs are routed through a diagnostic loop checking charging efficiency, thermal behaviour, voltage consistency, and overall health. Failures are auto-flagged, the station operator marks the pack as defective, and the manufacturer is obligated to repair or replace within the agreed SLA.

  • Single registered ecosystem
  • Warranty-linked unlimited swaps
  • SLA-backed defective handling

Outcome

An EV experience without the charging fear

A customer can buy an EV and drive or ride as much as they want, without the fear of finding — or waiting at — a charging station. Replace today's 45–120 minute charges with sub-5-minute verified swaps, and reduce overall vehicle cost in the process.

A perfect charging infrastructure plus a well-architected battery system can resolve the bulk of EV adoption issues we see today.
