Essential Guide to Choosing Charging Station Equipment for
Heavy-Duty Trucks: Integrated or Split Units? Which is More
Suitable for You?
With the increasing popularity of new energy heavy-duty
trucks, the demand for charging station construction is
growing. Improper selection of charging piles can lead
to low charging efficiency, increased operating costs,
and even affect user experience. So how do you choose
the right charging pile?
Currently, the mainstream charging equipment on the
market is mainly divided into two types: integrated and
split units. Both have their advantages and
disadvantages and are suitable for different charging
scenarios. How to make the best choice according to your
own needs? HARDHITTER will analyze from multiple
dimensions to help you make an accurate and appropriate
purchasing decision.
I. Integrated Unit: Simple and Economical, with
Relatively Fixed Power
1、Lower Cost, High Cost-Effectiveness
The components of the integrated unit are highly
integrated, resulting in relatively low production costs
and more economical prices. This is a very important
consideration factor for projects with limited budgets.
Applicable Scenarios:
If your charging station has a small scale, limited
investment budget, and does not require high charging
power and expandability, an integrated unit is a
cost-effective choice. The lower maintenance cost of the
integrated unit also makes it an ideal choice for small
charging stations.
2、Easy Installation, Save Time and Cost
All components of the integrated unit are integrated
into one box, making the installation process relatively
simple and requiring no complex wiring or assembly work.
3、Easy Maintenance, Reduce Operating Difficulty
The integrated unit has fewer components and a
relatively simple structure, making troubleshooting and
maintenance easier. This is particularly beneficial for
small and medium-sized charging stations that lack
professional operation and maintenance personnel.
II. Limitations of Integrated Units
1、Limited Expandability, Difficult to Meet Future Needs
The power of integrated units is usually fixed and
difficult to flexibly expand according to needs. If
future charging demand increases, integrated units may
not be able to meet higher power requirements.
Recommendation: If you expect significant growth in
charging demand in the future, or if the scale of your
charging station will expand, an integrated unit may not
be the best choice. When choosing an integrated unit,
consider the power limit and reserve some redundancy.
2、Fixed Power per Pile, Inflexible Scheduling
In scenarios where multiple heavy-duty trucks charge
simultaneously, integrated units cannot flexibly adjust
power distribution according to the actual charging
needs of the vehicles. For example, when one vehicle
needs fast charging due to low battery, while another
vehicle only needs slow charging because its battery is
high, the integrated unit can only charge at the set
power, unable to prioritize urgent vehicles.
For some large charging stations with complex and
variable charging needs, integrated units may not meet
the needs of efficient operation.
Heavy-duty truck batteries have large capacity and
fluctuating charging power requirements, leading to
relatively long charging times. If the charging station
cannot flexibly schedule according to the charging needs
of different vehicles, it can easily lead to the
following problems: Low charging efficiency: Unable to
prioritize vehicles with low battery, leading to
extended charging time. Waste of power resources: Some
vehicles charge at too high a power, leading to waste of
power resources. Poor user experience: Long charging
time affects user satisfaction.
3、Heat Dissipation Issues Need Attention
Since all components are integrated together, heat
dissipation issues of integrated units are relatively
prominent. If the heat dissipation design is poor, it
may cause equipment overheating, affecting equipment
life and charging efficiency.
When choosing an integrated unit, pay special attention
to heat dissipation design, such as heat dissipation
fans, heat sinks, etc. Regular maintenance is also
required to ensure the normal operation of the heat
dissipation system.
4、Compatibility May Be Limited
Some integrated units may not be compatible with all
types of heavy-duty truck models and charging standards.
When choosing an integrated unit, confirm whether it
supports commonly used charging interfaces and protocols
for heavy-duty trucks. If your charging station needs to
serve multiple brands and models of heavy-duty trucks,
it is recommended to choose an integrated unit with
broader compatibility. In addition, pay attention to the
upgrade and replacement of charging standards to ensure
that the integrated unit supports the latest charging
protocols.
III. HARDHITTER Split Units: Intelligent Power
Scheduling, Flexible and Efficient
Compared with integrated units, split units have higher
flexibility, expandability, and intelligent levels,
making them more suitable for large charging stations
and scenarios with higher requirements for charging
efficiency.
1、Flexible Configuration, Meeting Diverse Needs
Split units generally consist of a charging host and
charging terminals, which can flexibly configure
charging terminals and power according to the number of
vehicles and charging power needs, meeting the charging
needs of different heavy-duty truck charging stations.
2、Intelligent Power Scheduling, Improving Operating
Efficiency
HARDHITTER split units are equipped with advanced
intelligent power scheduling charging technology, which
can monitor the charging needs and battery status of
each vehicle in real-time and intelligently allocate
power.
① Power Allocation According to Demand:
When a vehicle's battery is critically low, the system
can prioritize allocating more power to it to ensure
rapid replenishment.
Other vehicles are allocated power reasonably according
to actual needs, avoiding waste of power resources.
② Improve Charging Efficiency:
The intelligent scheduling system can optimize the
charging process, reduce charging time, and improve
charging efficiency.
③ By optimizing power allocation, reduce power loss and
lower operating costs.
3、Modular Design, Smooth Expansion
HARDHITTER split units adopt modular design, which can
flexibly increase charging power according to the scale
and usage needs of the charging station. The power of
the charging host can be continuously expanded, better
adapting to the future development needs of the charging
station and reducing initial investment costs.
4、Charging Terminals Support Liquid Cooling Upgrade
HARDHITTER split unit charging terminals can be upgraded
to liquid cooling terminals, improving charging speed,
while supporting Ultra-Chaoji and other high-power
standards, meeting the growing demand for high-power
charging, and ensuring fast and efficient charging for
heavy-duty trucks.
5、Broader Compatibility
HARDHITTER split units support multiple charging
protocols and are compatible with more brands and models
of heavy-duty trucks, better serving different types of
users.
IV. Limitations of Split Units
1、Higher Initial Investment Cost
Due to the inclusion of multiple components, the initial
purchase cost of split units is usually higher than that
of integrated units. However, in the long run, the
higher flexibility, expandability, and intelligent
scheduling capabilities of split units often bring
higher return on investment. Therefore, it is
recommended to conduct a detailed cost-benefit analysis
when choosing split units, comprehensively evaluating
initial investment and long-term operating costs to make
a wiser decision.
2、Certain Requirements for Site Scale
The advantages of split units lie in efficient power
scheduling and flexible expansion according to demand,
making them more suitable for larger charging stations.
If your charging station is small, the advantages of
split units may not be fully utilized, and the initial
investment cost is higher. Therefore, for smaller sites,
it is recommended to carefully choose split units. For
larger charging stations with higher requirements for
charging power and expandability, split units are
undoubtedly the better choice.
V. Summary
Choosing between an integrated unit or a split unit
depends on the specific application scenario and needs:
If you have a limited budget and do not require high
charging power and expandability, an integrated unit is
a good choice.
It is recommended to choose products with good heat
dissipation performance and broad compatibility, and
conduct regular maintenance and upkeep.
f you want your charging station to have higher
flexibility, expandability, and compatibility, or have
higher requirements for heat dissipation and
