The Cold-Climate Challenge

Extreme Cold Is Brutal on EV Batteries

In high-latitude and high-altitude operations, the battery is the weakest link. We turn that risk into a managed, measurable service.

Up to 40%
Range lost in deep cold

Sub-zero temperatures sharply reduce usable capacity and driving range when fleets can least afford it.

2-3×
Faster degradation risk

Charging cold cells and repeated thermal stress accelerate long-term capacity fade.

Hours
Slower cold charging

Below freezing, charge acceptance drops and sessions stretch far beyond their rated times.

Our Services

Four Services, One Cold-Climate Mission

From live data to physical infrastructure and the capital to fund it — an end-to-end program for electrified fleets in the harshest climates.

Cloud Fleet Telematics

Real-time visibility into every vehicle: location, state of charge, cabin and pack temperature, and charging status, streamed to one dashboard.

Predictive Battery Analytics

Models forecast state-of-health and remaining useful life, flagging at-risk cells before cold weather turns a warning into a failure.

High-Voltage ESS Consulting

Design, siting, and commissioning guidance for high-voltage energy storage systems that stay reliable through sub-zero winters — buffering charging demand and keeping depots online when the grid is stressed.

Co-Investment, Leasing & Commercial Management

Flexible co-investment, leasing, and commercial-management structures for green-tech components and energy infrastructure — so you scale capacity without carrying it all on your balance sheet.

Battery Thermal Management, Built for the Cold

Managing heat — and the lack of it — is the core of cold-climate battery service. We combine live telematics, predictive analytics, and storage know-how into one program that keeps packs in their safe operating window.

Pre-conditioning
Warm packs to their optimal window before driving and charging to protect capacity.
Thermal-aware charging
Charge rates adapt to cell temperature to avoid cold-induced lithium plating.
Continuous monitoring
Pack temperature and health are tracked around the clock, all winter long.

Electrify Your Fleet — Even at −40°C

Tell us about your operating environment and fleet, and we'll map out a cold-climate battery service program built around it.
