What is fast charging?
Fast charging utilizes modern power electronic technology to return
energy to industrial batteries faster than conventional charging.
Fast charging typically delivers 40 amps or more per 100 ampere hours of battery
capacity. This can eliminate the need to change batteries on electric
trucks, increasing productivity and reducing cost.
How fast are the Aker Wade fast chargers?
Aker Wade fast chargers allow you to charge 12-to-80-volt industrial
lead acid batteries at currents of up to 650 amps, bringing a battery
from 30% to 80% state of charge (SOC) in about an hour,
depending on battery size.
Can fast charging save me money?
Absolutely. Fast charging can eliminate the need for truck battery
changes so that multi-shift operations are able to run on one battery.
This translates to higher labor productivity, energy savings, and
increased availability of manufacturing floor space for a quick
ROI.
What applications are suitable for Express Fast chargers?
The fast charging systems are suited to heavy-duty two-and three-shift
operations in manufacturing, distribution centers and ground service
equipment.

Is fast charging safe?
Yes, fast charging is safe. All components of the systems are
UL/cUL approved.
What does opportunity charging mean?
Opportunity charging with dedicated fast chargers means that operators
can charge batteries on their trucks during shift breaks in order
to maintain the battery's SOC between 30% and 80%, eliminating the
need to take the truck out of service for battery changes.
What is the difference between a dedicated,
parallel and sequential system?
Dedicated systems deliver all of their DC output to one battery,
returning the most energy to the battery during a given amount of
time. Parallel chargers divide the power output over multiple substations.
Charging multiple vehicles simultaneously reduces the amount of
energy returned to each battery. Sequential chargers are multi-vehicle
systems that charge one battery at a time, switching to another
battery only when a lower state of charge is detected among the
vehicles attached.

What is insulated gate bipolar transistor
(IGBT) technology?
IGBT semiconductor technology represents the latest power electronic
circuitry available for high-power industrial applications. The
IGBT is a high-frequency switch that enables high current outputs
with the greatest efficiency and power factor.
What is the difference between the
three base charger technologies: Ferroresonant, SCR and IGBT?
A Ferroresonant charger is capable of charging only one battery
voltage. It has a relatively low efficiency rating. An SCR charger
has multi-voltage capability; however the power factor varies depending
on the specific battery voltage being charged. An IGBT charger is
also multi-voltage, with a high power factor across the range of
battery voltages. The IGBT system monitors the battery voltage response
more than 10,000 times per second and safely maximizes the charging
current without significant losses.
What are the benefits of dedicated
IGBT chargers?
Dedicated chargers ensure sufficient power to operate on a single
battery through multiple shifts. IGBT power technology provides
maximum efficiency for minimal electrical infrastructure costs. Aker Wade is the only company to manufacture dedicated fast chargers with or without a battery module ID (BMID).
Do I need a special battery to
fast charge?
All major battery manufacturers have batteries available that
can accept the increased currents associated with fast charging.
Aker Wade fast chargers automatically recognize all batteries from
12 volts to 80 volts.

How does fast charging affect the gassing
of the battery?
The effect of fast charging on the battery is no different from
conventional charging. In addition, during all phases of fast charging,
gassing levels are below OSHA/NIOSH accepted limits.
How large are the fast chargers?
The dimensions (WxDxH) of the Aker Wade fast chargers are as
follows:
UniMAX 20,30,40: 21" x 26" x 46", TwinMAX 20,30: 33"
x 32" x 52" and TwinMAX 10,15: 21" x 26" x 46",
These fast chargers offer the highest kilowatts
per floor space required.
What kind of data is collected?
An Aker Wade fast charger automatically identifies the battery
for charge optimization and provides data on voltage, temperature,
charge time and ampere hours returned. Software is available for
more thorough analyses of all aspects of the charge cycle.
Is special training required for fast charging?
Operators need only basic instruction in how to connect and
operate the unit.
Is there a battery made specifically for fast charging?
Yes, EnerSys is the only industrial battery company that manufactures a battery from the ground up specifically for fast charging applications. The Express fast charge battery is designed to have the highest charge acceptance in the industry,
allowing operations to push more amps back into the battery faster, while managing the heat created so the battery is not damaged. The Ironclad® square tube technology behind the Express battery provides the most capacity available in standard battery dimensions. This capacity advantage also means that when dropping a plate size to accommodate vents, the Express battery can still exceed the capacity of a standard flatplate battery without vents.
How will fast charging affect the
life of my battery?
Fast charging does not create more wear and tear on a battery than
conventional charging. Electronically controlled charge algorithms
ensure a safe and effective battery recharge. The total ampere hour
life of the battery remains unchanged. Fast charging simply increases
the energy return rate.
What is the life expectancy of an Express Fast Charge battery?
Warranty states three years based on 160% of the rated battery capacity per day. The warranty also requires at least one equalize charge per week.
What is needed to maintain my Express Fast Charge battery properly?
The Express battery comes fully equipped with watering systems, dual cables and connectors designed especially for ease of connection to the Express fast chargers.
