Performance Comparison

Key Metrics: Sodium Ion Technology

THE GOAL - EXTRACT AS MUCH BATTERY ENERGY AS POSSIBLE AT A VOLTAGE ABOVE 12v

The Sodium Ion Battery addresses the challenge of delivering over 90% of nominal battery energy at 12 volts and above by utilizing an Electronic Storage System (ESS) management controller that boosts the load voltage with an additional series-connected battery cell.


The following diagram illustrates the output voltages of various battery chemistries, highlighting that the regular Sodium Ion, shown second from the bottom, has a wide voltage range from zero to 15.8 volts.

THE GOAL - Maximize Energy and Minimize Risks Above 12V with Sodium Ion

The comparison demonstrates how the Sodium Ion Battery elevates the energy curve to 12 volts and above, delivering 90% of nominal battery energy, effectively doubling the capacity of a regular SIB and providing over twice the energy of a premium quality AGM battery.

The following diagram displays energy and voltage measurements from a laboratory test of a Premium AGM and a Boosted Sodium Ion Battery with similar nominal Amp-Hour capacities, illustrating that the battery provides approximately 360% more energy than the AGM, all above 12 volts. While the AGM can safely discharge down to 10 volts, it risks reduced battery life and capacity with repeated use, and both AGM and lithium batteries enter a critical operating region below 10 volts where irreversible damage can occur. In contrast, the Turbo Boost remains unharmed at these lower voltages and delivers its results at a lower cost than LFP, Lithium Ion, or AGM batteries.
