Unchecked EV Expansion Is Over.
– Energy efficiency is now essential for the next phase of EV growth.
The EV market is no longer in its early distribution phase.
It has entered a stage where performance and efficiency must be verified.
As of the first half of 2025, EVs (including PHEVs) account for an estimated 21–23% of new car sales globally.
This exceeds the IEA’s 2025 target of 20%, and already reaches over half of the 2030 target (35%).

Electric vehicles have become widespread.
Now we must ask:
“Are EVs truly economical?”
“Are they genuinely contributing to environmental goals?”
1. Battery-centric strategies are hitting a wall
To date, the EV industry has relied heavily on two approaches:
- Increasing battery energy density for longer range
- Using low-cost LFP batteries to lower purchase price
However, these approaches are creating new burdens.
Heavier batteries are increasing overall vehicle weight
Tire wear is accelerating
Braking losses and frequent charging stress are passed directly to the driver
As a result, real-world energy efficiency is declining,
and the associated operating costs and maintenance burden fall entirely on the user.
The time for mere spec expansion is over.
What’s needed now is a shift in focus - to how we use less electricity, and use it longer.
2. Not all EVs are equally clean or efficient
EVs are widely regarded as eco-friendly simply because they run on electricity.
But the carbon impact depends entirely on how that electricity is generated.
In countries with a high share of renewable energy,
EVs provide clear carbon reduction benefits.
In regions dependent on coal or natural gas,
EVs often fail to deliver meaningful carbon savings—
and in some cases, indirect emissions can exceed those of ICE vehicles.
Driving environments also impact efficiency:
Regenerative braking varies significantly by terrain and driving pattern
Routes with frequent inclines, traffic, or stop-and-go movement
increase battery load and charging frequency
EVs are not inherently clean.
They are only as clean as the electricity they can effectively use.
That’s why energy efficiency technologies matter—
because they minimize waste and extend usable energy,
regardless of grid composition or terrain.
3. Leading OEMs are shifting to efficiency as a core strategy
Global automakers are already pivoting toward operational efficiency.
Stellantis is filing patents focused on maximizing energy recovery
Daimler will shift its EV bus sales model to TCO (Total Cost of Ownership) by 2025
BYD is scaling its regenerative braking–battery linkage system
and turning recovered energy into a revenue-generating asset
It’s no longer about battery size or acceleration specs.
Efficiency per kilowatt-hour is becoming the new competitive metric.
4. Deogam doesn’t manufacture EVs.
We help EVs use electricity differently.
DEOGAM does not build vehicles.
We design systems that recover and reuse energy that EVs have historically wasted.
EnerShift is not just a recovery device.
It is a technology that:
Quantifies the energy recovered during driving
Measures actual reductions in operating cost
Enables better decision-making for EV operation and deployment
Based on real-world trials in Korea, we’ve validated:
Recovered energy per kilometer (Wh/km)
Energy savings by route pattern (%)
Reduction in battery stress due to recovery circuits
What the EV market needs now isn’t a new car.
It’s a smarter way to move the ones we already have.
EVs are no longer scarce.
The question now is:
“How do we ensure that electricity is not wasted?”
DEOGAM is a component provider for EV energy efficiency.
We offer solutions to make the same electricity go further, cheaper.
It’s not about using more.
It’s about using better.
That’s the future we’re building at DEOGAM
