| Overview: |
|
Due
to oil
shortage and the effect of Kyoto Protocol, the high-tech and
eco-friendly electric vehicle has become one of the most popular
“green industries” in the world.
An Electric vehicle is a vehicle propelled by electricity instead of a
fuel engine. Common applications are e-bike, e-scooter, HEV, and BEV.
Except for HEV, these applications are pure electric-power systems,
which accomplish zero emission.
If
50%
of global annual production of lead-acid battery is adapted to electric
vehicles, which include e-bike, e-scooter, power chairs and e-car, it
could provide the power for 380 million vehicles using. This energy
equals:
|
Electricity generated by 10
San-xia dams
110 million gasoline saving
Reducing
224 million CO2 emission, which equals the forest as larger
as the
area of Italy.

However,
lead-acid battery features low energy density (30Wh/kg), and low energy
transfer efficiency (60%) as well. To drive the heavy application such
as BEV needs big power, which means more lead-acid batteries are
required. It's a vicious circle because of more waste electricity. Due
to safety concerns, however, there is no proper substitute. Now,
LiFePO4 battery features high safety, high energy density (120Wh/kg)
and perfect energy transfer efficiency (95%). It is a great substitute
for lead-acid battery.
Replacing lead-acid battery with LiFePO4 batteries can reduce 85% of
lead usage. The lead reduction can provide power

For 323 million electric
vehicles
And
is equal to the capacity of 40 nuclear power plants. |

| E-Bike |
|
E-bike
may be an important transportation for short distance. With a motor as
an auxiliary power unit, the speed can be up to 20km/hr, and the power
durability is over 40km. It satisfies with urban requirements. Even if
the e-bike runs out of power on the way home, user still can ride it as
normal bike. For recreation purpose, the user can ride easier on steep
grades with the auxiliary power unit. So an e-bike can provide a more
joyful ride than a normal bike.
Here’s
the comparison of lead-acid battery and Aleees’s HIBS (under
the same power output):

| More
importantly, 85%
capacity of Aleees’s HIBS battery can be charged in 15
minutes.
It means the user doesn't have to waste a lot of time charging. |
 |
| E-Scooter |
|
Although
motorcycle is smaller than car, the former’s emission is 3 to
4 times of latter’s. At present, there are
more than 10 million motorcycles in Taiwan, which emit more than 330
thousand tons of CO every year. It causes great impact for ecology
system and human life as well
|
|
Because
e-scooter is propelled by electric instead of petrol, there is no
emission problem. The battery charge can be done by normal DC outlet.
Comparing with the rising oil price, the energy cost is relative low.
Currently, the durability of lead-acid battery for e-scooter is about
40km per full charge. It spends about 2000Wh for full charge. Under the
same energy consumption (2000Wh), Aleees HIBS battery is
workable
for 55km because of transfer efficiency and energy density improvement.
95 unleaded gasoline costs about 0.85USD per liter (in Taiwan), and it
can run a motorcycle for about 35km. According to the above
information, we can have the comparison below:

| Also,
the fast charging capacity (15 minutes restores 85% capacity) gives
more advantage for Aleees HIBS battery in e-scooter
applications. |

| Power Chair |
| Power
wheelchair
and e-scooter are used for disabled or injured people. In the medical
rehabilitation industry, e-scooter and power wheelchair are mainly for
the means of transportation for aged and disabled people. At present,
e-scooters are equipped with Lead-Acid batteries for power storage.
However, Lead-Acid batteries are low energy efficient and cause a high
level of pollution. Replacing them with HIBS batteries can raise the
energy efficiency and make the e-scooter more compact. |

| Hybrid
Electric Vehicle
(HEV) |
| There
are two commonly
available electric vehicles: Battery on Electric Vehicles (BEVs) and
Hybrid Electric Vehicles (HEVs). HEVs are equipped with electric motors
and combustion engines. The vehicle computer shifts to the combustion
engine to power the vehicle while there is low voltage in the battery.
The unique regenerative braking system is able to convert movement
energy back to electricity, which means batteries can be charged by
putting on the brakes, and there’s no external plug-in
necessity.
Additionally, according to tests, HEV can save 50% of fuel in the city,
and 20% of fuel on the highway. |
