About the company: 

Energy Storage company that is focused in deploying BESS (Battery Energy Storage Systems) to accelerate integration renewable energies in our main stream power generation sources.

Newly established in Québec and seeking to develop the technology from within the Québec ecosystem.

Describe the project.: 

Reused Li-ion batteries from EVs normally have a considerable amount of energy left in them. EV batteries are replaced after they lose ~20% of capacity, which means they still possess ~80% capacity. This energy can be used for stationary storage applications, such as a local microgrid. Tapping into the remaining battery life has the potential to cut costs and greenhouse gas emissions. However, this scenario still presents several challenges. This project presents the design, construction, development, and testing of a “plug-and-play,” modular test bench for second use Li-ion batteries, specifically geared towards energizing smart microgrids. The system will be capable of performing accelerated life cycle tests at the pack and module level, and will depict details, such as capacity, maximum voltage, minimum voltage, maximum charge current, maximum discharge current, charge temperature range, and discharge temperature range. The pack will consist of heterogeneous reusable Li-ion cells acquired from automotive OEMs.

Required expertise/skills: 

- PhD in Electrical Engineering
- Estimation techniques for state-of-charge (SOC) and state-of-health (SOH) of EV batteries using AI/ML algorithms
- Design and development of a smart power-electronics-intensive active battery management system (BMS)
- In-depth knowledge of power electronics and control, specifically DC/DC converters
- Verify the developed models and prototypes on microgrids and DC fast chargers
- Experience in grid integration of electric energy storage systems and DC fast charging technology is a bonus

Apart from the above-mentioned roles and responsibilities, this Postdoctoral Fellow position with Dr. Sheldon Williamson at Ontario Tech University, is expected to work closely with the associated industry partner, while at the same time mentoring graduate students in strategic related areas. The incumbent will also participate in manuscript writing for publication in top journals such as IEEE Transactions. Other duties as assigned, which include lab/testbed maintenance, organizing and attending meetings, presenting results in major IEEE Conferences and workshops.
