Motive / Traction Batteries

Sodium-Ion Batteries Built for
Industrial Fleet Electrification

From electric forklifts in cold storage to commercial EV fleets at scale, Coulomb Technology's sodium-ion systems deliver consistent power across extreme temperatures — with no thermal runaway risk and no foreign mineral dependencies.

Why Coulomb Technology for Motive / Traction Batteries

Engineered for the Demands of Fleet Electrification

Electrifying a fleet means committing to batteries that work as hard as your vehicles — across every shift, every temperature extreme, and every charge cycle. Coulomb Technology's sodium-ion systems are purpose-built for motive and fleet applications where lithium's limitations become operational liabilities: cold storage performance loss, thermal incident risk, and foreign supply chain exposure.

Cold Storage Performance

Full rated capacity in freezer and cold storage environments where lithium-ion loses 20–40% capacity — no heaters, no oversizing required.

Zero Thermal Runaway Risk

Sodium-ion chemistry is inherently non-flammable — no fire suppression systems required in warehouses, depots, or enclosed vehicle bays.

Fast Charge Compatible

Supports opportunity charging and fast-charge protocols without accelerated degradation — keeping your fleet moving through every shift.

Domestic Supply Chain

No cobalt, no lithium, no exposure to foreign mineral supply chain disruptions — sodium is domestically abundant and price-stable.

Motive / Traction Batteries Applications

Four Fleet Segments Where Coulomb Technology Delivers

Every fleet electrification project is engineered around your specific duty cycles, facility constraints, and operational requirements.

Electric Forklifts and Material Handling
1
Material Handling

Electric Forklifts & Material Handling

For: Distribution Centers, Cold Storage Warehouses, Food & Beverage Facilities, Manufacturing Plants


The Challenge

Forklift fleets operating in cold storage and freezer environments face a critical problem: lithium-ion batteries lose 20–40% of their capacity below 0°C, forcing operators to oversize battery packs, add heating systems, or accept reduced shift coverage. Thermal incidents in enclosed warehouses create unacceptable safety and insurance risks.

The Coulomb Technology Solution
  • Full rated capacity from -40°C to +55°C — no cold-weather performance loss
  • Inherently non-flammable chemistry eliminates warehouse fire risk
  • No battery heating systems required — lower auxiliary power draw
  • Supports multi-shift operations with opportunity charging between shifts
  • 6,000+ cycle life reduces total cost of ownership vs. lead-acid and lithium
Fleet Charging

Commercial EV Fleet Charging

For: Trucking Fleets, Transit Agencies, Utility Fleets, Corporate Vehicle Fleets, Rental Fleets


The Challenge

Large commercial EV fleets create massive demand spikes when multiple vehicles charge simultaneously — driving up demand charges, straining grid connections, and requiring expensive utility upgrades. Fleet operators need energy storage that can buffer peak demand, reduce charging costs, and maintain uptime through grid outages.

The Coulomb Technology Solution
  • Behind-the-meter BESS eliminates demand charge spikes from simultaneous charging
  • Enables fleet charging without costly utility service upgrades
  • Stores off-peak energy to reduce charging cost per vehicle mile
  • Backup power maintains charging operations during grid outages
  • Pairs with on-site solar for net-zero depot operations

Port and Terminal Equipment

Port & Terminal

Port & Terminal Equipment

For: Container Terminals, Cargo Ports, Intermodal Yards, Marine Terminals, Rail Yards


The Challenge

Port and terminal operations run heavy equipment — cranes, yard tractors, reach stackers, and AGVs — in demanding coastal environments with high humidity, salt air, and extreme temperature swings. Equipment downtime is measured in millions of dollars per hour, and fire incidents in port facilities create catastrophic liability and operational disruption.

The Coulomb Technology Solution
  • Corrosion-resistant chemistry suited for high-humidity coastal environments
  • Non-flammable sodium-ion eliminates fire risk in high-value cargo areas
  • Wide temperature range handles coastal climate extremes without derating
  • High cycle durability supports 24/7 continuous operations
  • Stationary BESS supports port electrification and shore power infrastructure
Airport GSE

Airport Ground Support Equipment

For: Commercial Airports, Cargo Terminals, Military Airfields, Private Aviation FBOs, Helicopter Pads


The Challenge

Airport ground support equipment — aircraft tugs, baggage tractors, belt loaders, and ground power units — operates in extreme outdoor environments with zero tolerance for fire incidents near aircraft, fuel, and passengers. Lithium-ion batteries face regulatory restrictions in many airside environments due to thermal runaway risk.

The Coulomb Technology Solution
  • Inherently non-flammable chemistry — no thermal runaway risk near aircraft or fuel
  • Full rated capacity in extreme outdoor temperatures from −40°C to +55°C
  • Supports 24/7 continuous operations with opportunity charging between turns
  • Reduced maintenance burden for high-cycle-count airside equipment
  • Domestic supply chain supports FAA and TSA procurement compliance requirements

The Economics of Sodium-Ion for Fleet Operations

Coulomb Technology's sodium-ion chemistry delivers a compelling TCO advantage for fleet operators — combining longer cycle life, lower maintenance burden, and elimination of costly thermal management systems with the price stability of domestically abundant sodium feedstock.
