EV Charging Solutions Designed Around the Way Vehicles Operate
How will vehicles actually use this location?
A car parked at an office throughout the working day does not need the same charging strategy as a fleet vehicle with a fixed departure deadline.
Power9 combines AC and DC charging options to help businesses evaluate charging infrastructure around actual operational requirements.
Workplace EV Charging
Employees may park for several hours at a workplace. That longer dwell time can make AC charging an efficient option for many compatible vehicles. The Power9 dual-gun AC charger provides two simultaneous charging outputs from one charging system, allowing two compatible EVs to charge at the same time.
Where selected workplace vehicles need faster turnaround, the 20/30 kW DC charger can also be evaluated.
- Employee dwell time
- Number of EV users
- Available electrical capacity
- Access management
- Future adoption
- Charging policy
Fleet EV Charging
Fleet charging has one overriding objective: Vehicles must have enough energy when they need to return to service. That means charger selection should follow the fleet’s operational schedule.
- Daily vehicle distance
- Battery capacity
- Return-to-depot time
- Next departure
- Charging window
- Number of vehicles
- Electrical capacity
- Expected fleet growth
Commercial EV Charging
Commercial properties may need to accommodate employees, visitors, customers, tenants or company vehicles. That makes flexibility important.
The Power9 product range gives projects two different approaches:
Dual-Gun Ac Charging
For longer-dwell charging and locations where two compatible vehicles may require simultaneous access.
20/30kW DC Charging
For applications where quicker vehicle turnaround is more important. The most appropriate combination depends on utilisation, electrical capacity and project economics.
Public & Destination EV Charging
Public and destination charging sites can have very different use patterns. A hotel, office or destination property may have extended parking periods. A higher-turnover charging location may need faster charging. Power9’s AC and DC product options allow projects to evaluate charging infrastructure according to dwell time rather than applying one charger type everywhere.
Apartment & Shared Parking Charging
As more residents adopt EVs, residential properties need to think beyond installing a charger for the first vehicle. The Power9 dual-gun AC system can be evaluated for compatible shared charging environments where the site’s electrical infrastructure supports the required installation.

How Power9 Approaches a Charging Requirement
1. Understand the Vehicles
What vehicles need charging and what charging capability do they support?
2. Understand the Charging Window
How long will each vehicle remain parked?
3. Assess Electrical Capacity
What power is available at the location?
4. Estimate Charging Demand
How much energy must be delivered before the vehicle leaves?
5. Select AC, DC or a Combination
Choose according to the actual operating requirement.
6. Plan for Expansion
Consider what happens when EV adoption increases.
Which Power9 Charger Fits Which Requirement?
| Requirement / Spec | AC Dual Gun (23 kW) | 20/30 kW DC Fast Charger |
|---|---|---|
| Two simultaneous charging points | Strong fit | No |
| Longer parking duration | Strong fit | Possible |
| Faster vehicle turnaround | Limited by AC/vehicle capability | Stronger fit |
| Workplace | Strong fit | Selected applications |
| Commercial property | Strong fit | Strong fit |
| Fleet | Longer-dwell fleets | Strong fit |
| Managed connectivity | Yes | Yes |
| Dynamic load management | Yes | Yes |
| Public/high-use charging | Selected applications | Stronger fit |
Actual application requires vehicle and site assessment.
Frequently Asked Questions
Is AC or DC charging better for a workplace?
It depends on how long vehicles remain parked and how quickly they need to recharge. AC charging can work well when employees remain parked for several hours. DC charging can be considered for vehicles requiring faster turnaround or for specific commercial/fleet requirements.
Why is load management important?
A charging site may have limited electrical capacity compared with the theoretical maximum demand of every charger operating at full power simultaneously. Load-management strategies can help control charging demand according to the electrical capacity and operational requirements of the site.
Can one site use both AC and DC chargers?
Yes, a mixed approach can make sense where different vehicles or users have different charging requirements. Longer-dwell vehicles may use AC charging while vehicles requiring quicker turnaround use DC charging. Final architecture should be based on a technical site assessment.
What information does Power9 need for a charging project?
Useful starting information includes the number and type of vehicles, their charging capability, typical parking duration, daily usage, project location, available electrical capacity and anticipated future growth.
