Nio claims its new standard range 75kWh hybrid cell battery will reduce the range loss in low temperatures by 25%.

Using its patented technologies, the new battery delivers both a longer range in cold weather and more accurate state of charge (SoC) estimation whilst matching the battery performance of a ternary lithium battery.

This new standard range battery (75kWh) is a hybrid of ternary lithium and lithium iron phosphate (LFP) cells using new generation cell to pack (CTP) technology.

To achieve the range peformance gain, engineers designed a complete thermal management software and hardware system for the battery. The hybrid layout of ternary lithium cells and LFP cells make full use of the low temperature performance advantage of such cells to improve the overall battery performance.

A dual chemistry control algorithm precisely controls the performance of ternary lithium and LFP cells in cold temperature to improve energy efficiency. In addition, a radiant thermal compensation heater uniformly heats the cells to maintain the working temperature of the battery while taking into account the energy consumption.

Further gains in passive thermal insulation were achieved using low thermal conductivity materials and an innovative structural design. The result was a reduction in range loss by 25% compared to its LFP counterpart in low temperature environments.

The self developed hybrid cell battery SoC estimation system integrates innovations in both software algorithm and hardware to reduce estimation errors to less than 3%, thereby reaching the level of ternary lithium battery SoC estimation. The dual chemistry SoC algorithm takes advantage of ternary lithium and LFP battery systems to guarantee accuracy. A high-power DCDC within the battery ensures fast, real time and balanced SoC calibration.

CTP technology simplifies manufacturing and assembly by 10%, increases volume utilisation by 55, and increases energy density by 14% to 142Wh/kg.

The standard and long-range ternary lithium battery (100kWh) are now available for new car orders with deliveries set for November.

Vehicle prices with the new 75kWh battery are the same as for the previous 70kWh battery.
