Repurposing EV Batteries into Energy Storage Systems

Repurposing Electric Vehicle (EV) Batteries on Vancouver Island

Repurposing electric vehicle (EV) batteries is revolutionizing the sustainable energy industry. These EV batteries, while no longer suitable for powering electric cars, still retain a significant amount of energy capacity, making them valuable resources for battery energy storage systems.

The Challenge/Solution

There will be an exponential increase in Electric Vehicle (EV) manufacturing and adoption worldwide. But what happens to the EV batteries when they need replacement?


EV batteries have up to 20 years of useful life in a stationary Energy Storage System (ESS). Rainhouse’s ultimate objective is to develop a tailor-made ESS by leveraging second-life EV batteries, which can serve as a reliable power source for a diverse range of industrial and community-oriented applications. For example: powering off-grid communities, marine projects and, on-grid load levelling.


Rainhouse Battery Energy Storage System

Battery Energy Storage Systems (BESS)

The Rainhouse BESS will reduce Canada’s reliance on fossil fuel-generated electricity in remote communities, accelerate the shift to green energy in the Albertan grid, allow small municipalities to participate in the energy market, defer grid investments, and provide a solution to the upcoming challenge of managing the EV batteries that will come off-road. Rainhouse’s BESS will be designed with safety and efficiency in mind. We plan to implement a comprehensive fire safety system that includes fire detection, advanced fire suppressants, and fire-resistant materials. We are utilizing geothermal heat pump technology to regulate ambient temperature.


On June 8, 2023 Rainhouse Manufacturing Canada Ltd. was selected as a funding recipient from the B.C. Centre for Innovation and Clean Energy (CICE)’s 2023 Open Call for Innovation. We are proud to receive a $750K grant from CICE, which will support our Battery Energy Storage System (BESS) project. We are actively seeking investors who share our vision and want to be part of our journey toward innovation and sustainable growth in Canada.

Benefits of BESS

By investing in green energy, we can reduce our reliance on fossil fuels and help mitigate the effects of climate change.


Other Benefits:
•Reduce air pollution from diesel generators.
•Reduce soil wastes from improper disposal of second-life EV batteries.
•Create custom energy solutions for each remote community.
•Assisting Indigenous and non-Indigenous Canadian communities in harnessing and using energy storage systems. This enables energy conservation as well as the opportunity to build stronger, lasting, positive relationships with indigenous communities.

Our battery manufacturing solutions are innovative, efficient, and sustainable
