Challenges faced by EV car makers using Lithium based batteries
- Lithium based batteries are heavy and bulky, have short life span, and are expensive to replace
- They have low power density. The fast acceleration required in daily driving conditions require battery to provide high surge of energy which will shorten battery life
- The most significant limitations of lithium batteries are slow charging and limited driving range. Without meaningful range and quick charging, cars can travel only intracity but not intercity
- EV makers need to find solutions to add on to existing range
- Battery Size/Weight/Capacity has reached a point of Diminishing Marginal Return, where by adding more battery will add on to total vehicle weight while yielding no additional range
- There is no sight of new Battery types in the horizon to replace the various commonly used Lithium Batteries
- The immediate solutions to alleviate these shortcomings do not entirely lie in the upgrading of battery technology. The problem can partly be solved by:
- More efficient ways to overcome Moment of Inertia
- Better capturing of Braking Kinetic Energy
- Improvement of Load Efficiency
- Our Graphene Energy Management System (GEMS) provides these immediate solutions.

- Supercapacitor is far more superior and effective in capturing Regenerative Braking Energy/KERS
- Dynamic and nanosecond algorithm control discharge of captured energy, to either load or reflow back the main battery tray
- Capturing and reuse braking energy extends range by more than 25%
- With high power density, supercapacitors can discharge stored energy in high momentarily ampere for vehicle to overcome moment of inertia. This helps protect and extend battery life.
- All motors generate Back Electromotive Force (EMF)
- 25-35% of energy is wasted to overcome Back EMF
- GEMS uses proprietary Thruster Technology to suppress/reduce Back EMF
- Effectively reducing 50-60% of Motor Back EMF
- With suppressed Back EMF :
- Increase in Motor efficiency
- Reduce load, save battery power
- Less power consumed
- Extends range of EV
