Teal Electricfication Systems Technology

Overcoming the problems electric vehicles face in harsh climates.

Teal’s Battery Technology extends the range and lifespan of your EV operating in climate ranging from -40° to +50° celsius.

All batteries need to be kept in a narrow temperature band for optimal performance all year around. Any temperature outside that band reduces the performance and range of the battery, as the battery expends energy to maintain an optimal internal temperature.

We’ve developed a portfolio of proprietary technology to address battery performance in harsh climates. These designs ensure EVs can see better adoption across the globe - especially in climates with extreme temperature ranges.

Thermal Management Design (TMD)

Electric vehicles have different, more demanding, temperature control requirements compared to conventional internal combustion power plants - especially in very hot or cold temperatures

Teal addresses the issues EV batteries face in harsh temperature ranges with a unique and proprietary climate management system. This system includes a patented smart valve system mated to a heat pump and a Thermal Storage System (TSS) to provide  heating and cooling to multiple places from multiple sources simultaneously.

This patented technology:

  • Keeps batteries in optimal operating temperature with a tight tolerance

  • Delivers waste heat for cabin heat and window defrosting

  • Seamlessly manages multiple temperature demands at the same time

Thermal Storage System (TSS)

Conventional engines produce an excess of heat from combustion. While a lot of this heat is wasted, some of it is used for secondary vehicle systems and climate control in the cabin space. Normal EV battery systems expend critical energy to maintain ideal temperatures, which in turn reduces driving range and performance in colder weather.

Along with batteries that deliver power for drive, Teal EV battery systems include a second patented 50kWh thermal battery to provide heat for optimal operating temperatures for the entire vehicle.

This patented technology:

  • Ensures a consistent (+/-15%) range in ambient temperatures between -40° to +50° celsius.

  • Maintains a 10 hour operating window between charge cycles before using any energy from the electric batteries.

  • Extends the overall battery life and range performance of the electric batteries.

High-Performance Battery Packs

Common battery pack technologies found in today’s market suffer from a number of compromises. Almost all the batteries are designed in a way that even if a single module fails the entire battery needs to be replaced. Exterior insulation and interior temperature management is often inadequate for use in harsher climates.

Teal’s battery packs introduce a completely new design intended for heavy-use and harsh temperatures.

Our patented Cell-to-Pack design offers a number of advantages over conventional EV batteries.

1. Patented Cell-To-Pack Architecture

When it comes to a heavy duty vehicle, longevity is paramount. With a unique and state-of-the-art architecture, Teal batteries are meant to be serviceable down to the cell level.

This ensures batteries can last their full lifespan of up to 20 years and offer the best in class total cost of ownership. This architecture allows technicians to replace a faulty cell or module in under 30 minutes if required. Giving you a peace of mind for making an investment in a safe and reliable technology meant to be a workhorse.

2. High Voltage From Day One

Higher voltage means lower currents and higher speeds, which translates to less copper and higher power density bringing you superior performance at lower cost and weight.

Employing an 750V battery system, Teal provides increased performance and efficiency without heavy and costly electrical components.

3. Superior Enclosure Build Quality

Teal batteries are sealed and insulated in a stainless-steel envelope that performs in any harsh environments with snow, gravel, road salt, and beyond.

4. Sophisticated Internal Air Flow Distribution

Our pack design offers an uncompromised internal temperature management system enabling a uniform temperature distribution across the whole pack while keeping the serviceability and simplicity a must.
