EVE V Series vs. P Series Cylindrical Battery Cells: What's The Difference?

We know cylindrical battery cells must fulfill technical requirements in many applications, from electric car energy density to power tool efficiency. Thus, we at EVE created our V series for energy-intensive usage and our P series for high discharge rates and power output. With optimized internal cell structure and materials, we guarantee each series maximizes dependability in its intended use.

This blog aims to illustrate the differences between the EVE V series cylindrical battery cells and the P series. Read on for their detailed comparison.

EVE V (or E) Series and P Series

V Series: Features

Our V Series cylindrical battery cells maximize energy density and life. They feature high nickel content in the cathode for higher energy storage within the same volume. The lifecycle of the V Series results from cell design for low degradation over time. For instance, we utilize a proprietary electrolyte formulation that decreases the rate of electrolyte decomposition for stability over thousands of charge cycles. Moreover, our thermal management techniques, including high-conductivity materials, help maintain the cell temperature within ranges for lower wear.

V Series: Applications

Given their energy density and life, our V Series cylindrical battery cells suit many demanding applications. In AGVs and forklifts, the V Series provides a reliable energy source for long operation. Two-wheelers, including electric scooters and balance bikes, benefit from these cells' lightweight yet powerful nature for longer rides on a single charge. The V Series delivers performance without frequent recharging for ESS (Energy Storage System) and cleaning robots. That's where compact size and high energy are key. The cells also outfit portable energy storage systems. The reason is that long-term durability and storing large amounts of energy in a compact form are essential here.

P Series: Features

Our P Series cylindrical battery cells are used for rapid charge and discharge cycles. They have a lower internal resistance through high-conductivity materials and electrode designs for a larger instantaneous discharge rate. The P Series also integrates fast ion transport technologies for swift energy flow during the charge and discharge phases. E.g., the anode materials in the P Series may comprise carbon composites for rapid lithium-ion cylindrical battery intercalation and deintercalation. The cell structure can handle the thermal stress of high-rate operations.

P Series: Applications

The P Series cylindrical battery cells suit environments that demand high power output and rapid recharge cycles. They drive high-performance motors for cleaning demanding surfaces for vacuum cleaners. Power and garden tools, including drills, saws, and trimmers, benefit from the P Series' quick, powerful bursts of energy for efficient operation. Further, their fast charge ability gives shorter idle time between uses for productivity in professional and DIY applications.
