Podium Advanced Technologies has designed the innovative four motors and turbine range extender architecture and the battery pack of Ren, the first production vehicle from the Chinese automotive company Techrules that made its debut at the 2017 Geneva Motor Show with an innovative design style signed by Fabrizio and Giorgetto Giugiaro.
The battery pack is designed and manufactured by Podium Advanced Technologies Engineering specifically for the Ren. It will come in three capacities of 14 kWh, 25 kWh and 32 kWh and can be charged to 80% capacity in under 15 minutes using a DC fast charger.
The target lifespan of the battery is 100.000 cycles. The batteries feature an innovative design and incorporate battery management technologies that enable superior charging efficiency and power balancing between battery cells. Each cell voltage and temperature are independently monitored. Cells are connected via a circuit board instead of wires, for greater durability. The pack can deliver 1.200 A, enough to drive six wheel motors at full power.
The battery management system (BMS) is integrated and designed to optimize the performance and life of the battery while ensuring absolute safety. There are three water cooling circuits for the motors, battery and inverter.
