Energy Storage Solutions

We’ve established Battery Manufacturing Capabilities on Vancouver Island

Battery manufacturing is one of Rainhouse’s newest ventures. We have been able to engineer and assemble battery packs using new and second-life EV battery modules and cells to learn everything there is in the process.


A little background on second-life EV batteries.

Over 40 car models have been discontinued in the last 10 years, and 110,518 BEV and PHEV  were sold in Canada alone between 2019 and 2020. There will be an exponential increase in Electric Vehicle (EV) manufacturing and adoption worldwide, but what happens to the batteries when they need replacement? EV batteries can be given a second life in energy storage systems (ESS) that can power everyday electronics, substitute generators, and load level or even power entire off-grid communities. EV batteries can be used to develop custom battery packs and ESS for a variety of applications to power off-grid communities, marine projects and, on-grid load leveling.



Our initial project to explore battery manufacturing capabilities was possible thanks to the Supply Chain Resiliency Grant from the government of BC. In partnership with Canadian Electric Vehicles (CanEV) and the University of Victoria Clean Transportation research team, we researched, learned, and established important supply chains and technical expertise to grow the industry in Victoria.

We also completed the conversion of lead-acid batteries to Lithium-iron phosphate batteries for a Genie – Telescopic Boom Lift used in the construction industry. Our client, Top quality coatings Ltd, was looking for an alternative to replace costly lead-acid batteries with a short lifespan with Lithium-iron phosphate batteries where the charge will last over a week of intense use and provide a 15 to 20 years lifespan.
