At the start of this month, we rebuilt the battery pack, incorporating the improvements designed last month. Building up the pack required our engineers to work long hours to ensure we met the test deadline. Although we were confident that the battery would pass this time, it turned out otherwise. During pre-checks, we noticed insulation issues due to changes in humidity, a problem we had not previously encountered. Consequently, we had to disassemble the battery again to identify the root cause. Eventually, through elaborate testing at Prodrive Technologies, the root cause was identified. This setback was very disappointing for the team. Fortunately, the cause of the problem is now clear, and many potential solutions are currently being tested in climate-controlled rooms. We still believe we can resolve these issues this summer.
Despite this setback in the battery pack development, we did achieve some successes in our other projects. For example, we fully integrated the refrigerant loop in the car. This loop, located between the battery’s cooling loop and the outside air, functions to dissipate heat from the battery to the outside air. A few months ago, this loop was performance-tested in the car, but now it is fully integrated!
Additionally, we received the transmission from Hewland, completing all components of the powertrain. This means we can gradually begin to integrate these components.
Next month, our main focus will be on resolving the humidity issues in the battery pack. If we manage to do this, we can start preparing for our first drive!
