The core components of a lithium-ion battery pack include multiple individual battery cells, a Battery Management System (BMS), thermal management systems, and a robust casing. The BMS is critical for monitoring and controlling the battery’s state of charge, temperature, voltage, and current, ensuring optimal performance and safety. The thermal management system regulates the battery’s temperature, preventing overheating or excessive cooling, which are vital for longevity and efficiency, especially in diverse Canadian climates like those experienced in New Brunswick.

How Lithium-ion Batteries Work

The operation of a lithium-ion battery relies on the movement of lithium ions between two electrodes—the anode (negative electrode) and the cathode (positive electrode)—through an electrolyte. This process occurs during both charging and discharging phases.

• During Discharge (Powering the Car): When the vehicle is driven, lithium ions move from the anode, through the electrolyte, to the cathode. Simultaneously, electrons flow through an external circuit, creating an electric current that powers the vehicle’s motor.
• During Charging: When plugged in, an external power source reverses the process. Lithium ions are extracted from the cathode and move back through the electrolyte to the anode, where they are stored. Electrons flow through the external circuit in the opposite direction, replenishing the battery’s charge.
• Electrolyte: This is a medium that allows lithium ions to move between the anode and cathode but prevents electrons from passing through directly. It is typically a liquid organic solvent containing lithium salts.
• Anode and Cathode Materials: The choice of materials for the anode and cathode significantly impacts the battery’s performance, capacity, lifespan, and cost. Common cathode materials include lithium cobalt oxide (LCO), lithium manganese oxide (LMO), lithium nickel manganese cobalt oxide (NMC), and lithium iron phosphate (LFP). Anodes are often made from graphite.
