Power Cells vs Energy Cells

EV drive uses Molicel power cells in our standard battery modules. Many other batteries, including those used by Tesla and most OEMs, use energy cells. The difference has to do with how the battery performs under a heavy load. Power cells have lower internal resistance, which means that they can deliver their energy more quickly without generating excessive heat.  

What this means for performance is that a small battery pack comprised of power cells can deliver the same amount of current as a larger pack with energy cells. For example, a 40 kWh power battery may deliver the same current as a 80 kWh energy battery. Naturally, it is possible to get all of the power you need by simply making your battery larger in capacity, but this comes at the cost of weight, space required, and expense.

This is particularly important in competitive or high-performance applications where the weight of a heavy battery pack itself interferes with the performance. Energy cell batteries shine when the goal is the highest range possible and performance is not the highest consideration. EV drive specializes in compact, lightweight performance, and this starts with premium power cells.
