LEV50 Battery Replacement Solution with CATL 93Ah or EVE 59Ah NMC Cell
Advanced Upgrade Solution for Mitsubishi i-MiEV / Peugeot iOn / Citroën C-Zero
1. Project Background
The Mitsubishi i-MiEV, Peugeot iOn, and Citroën C-Zero are among the earliest mass-produced electric vehicles in the global EV market. After years of operation, most original LEV50 battery modules are experiencing significant capacity loss, shortened driving range, reduced charging efficiency, and aging-related performance degradation.
As replacement OEM battery modules become increasingly limited and expensive, vehicle owners require a practical, high-performance, and cost-efficient upgrade solution. In response to this market demand, NOGI developed a modern LEV50 battery replacement system utilizing advanced CATL 93Ah and EVE 59Ah lithium cells.
2. Development Philosophy & Solution Origin
The core idea behind this project is to preserve the original vehicle platform while dramatically improving battery performance using newer-generation lithium technology.
- Restore and extend EV driving range.
- Increase battery energy density and cycle life.
- Maintain compatibility with original vehicle systems.
- Reduce replacement costs compared to OEM solutions.
- Provide sustainable long-term support for aging EV platforms.
Modern lithium-ion technology has evolved significantly compared to early-generation LEV50 cells. CATL and EVE cells offer improved energy density, voltage stability, safety performance, and service life. By integrating these cells into the original battery structure, NOGI created a balanced upgrade solution that combines modern battery performance with OEM-style integration.
