As Polar Bears Test the Ice, This Mobile Research Station is Camera-ready

As temperatures drop and ice sheets form on the shores of Canada's Hudson Bay, polar bears waiting ashore can finally take to the ice and resume their favorite activity: hunting seals.

 

Meanwhile, Polar Bears International has been monitoring the shoreline from Tundra Buggy One, a roving research vehicle and broadcast studio used to study the bears and to share their story with the world via the Explore.org LIVE Polar Bear Cam and special broadcasts like this special on ABC's Good Morning America

 

 

"Bear season is short, and Polar Bears International has a limited amount of time each year to communicate the story of the polar bear and climate change," says BJ Kirschhoffer, Director of Conservation Technology at Polar Bears International. "We also operate in a harsh climate where power failure or long downtime can be dangerous."

 

Intelligent Controls worked with BJ to double the onboard battery capacity of Tundra Buggy One. The new battery bank powers everything on board, including the networking and wireless communication equipment that allow video streaming; a full webcast studio, complete with an encoding computer, studio lights, and mixer; and an exterior PTZ camera to film the polar bears.

The new system includes eight 12 Volt Pylontech batteries and a Victron Energy Cerbo GX device. The Cerbo allows this mobile off-grid power system to be monitored online via Victron's remote management platform (VRM).

"Lithium batteries give us reliability, predictability, and longevity not seen by traditional battery chemistries," says BJ. Increased power capacity allows the Buggy to pull 600 watts for nearly six hours, powering lights, cameras, and encoders without stress.

"Since the Pylontech battery management system communicates with the Cerbo GX, I can easily monitor our energy draw and remaining capacity with a high degree of accuracy, relieving any stress relating to running out of power mid-broadcast."

    Victron Charger Naming Convention

    Victron engineers took everything they knew about building the best inverter/chargers and scaled that down to an excellent line of about 10 different battery chargers, each designed for specific applications and needs. As you look at the variant name for each product on our website, here's the naming convention you'll see used and what it means.
