Direct Answer
Fleet charging selection is a site-and-duty-cycle decision, not a single-product decision. Whether the fleet is a municipal or utility fleet (government) or a logistics, taxi, rental, shuttle or corporate pool fleet (commercial), the same core criteria determine the right AC charging configuration - fleet connector mix, required power versus vehicle dwell time, site electrical capacity and load management, user access and backend control, billing/metering needs, protection and environmental rating, and the certification path for the target market.
For overnight depot and workplace charging, AC wallbox chargers in the 7 kW, 11 kW and 22 kW range are the usual starting point.
Key Takeaways
- Downtime risk. A charger that underperforms at a depot can take several vehicles out of service at once.
- Power risk. Selecting 22 kW models on a site that cannot support them may lead to derating, nuisance tripping or expensive electrical upgrades.
- Compliance risk. A model that is suitable in one country may require different documentation in another. Certification applies by model, market, sales channel, certificate holder and authorization method.
- Billing and access risk. Without the right user access and metering configuration, the site cannot allocate cost fairly between departments, tenants or drivers.
- Pilot risk. Fleet deployments are usually phased. Starting with proofs or a small pilot reduces the cost of getting the specification wrong.

Detailed Answer
"Fleet charging" covers two different buyer groups with overlapping technical needs -
In both cases, the charger is not bought for a single driver. It is bought for a repeated daily cycle across multiple vehicles, multiple users and often multiple years of operation.
This changes the selection logic compared with home charging -
YIYANG SHENDA's product line is focused on AC charging, including wallbox chargers, portable chargers, charging cables, adapters and accessories. Its knowledge base notes that the company is not a full-line DC fast charging supplier, so fleet projects requiring DC fast charging should be reviewed as a separate technical category.
Key Industry Insights
Fleet charging decisions carry different risk than single-unit purchases -
For public-sector buyers, the practical risk is often documentation completeness; for commercial operators, it is usually uptime and total cost of ownership.
FAQ
What AC power level should a fleet site choose first?
It depends on dwell time and site capacity. 7 kW single-phase is often sufficient for long overnight dwell; 11 kW and 22 kW are typically considered where three-phase supply is available and dwell time is shorter.
Can the same wallbox model serve both government and commercial fleets?
Physically, yes in many cases. Commercially, the difference is usually in configuration and documentation — for example access control, metering, backend connection and the tender documentation package.
Does fleet charging require OCPP?
Not automatically. OCPP becomes relevant when the site needs central monitoring, user authentication, roaming or billing through a charging management platform. OCPP support depends on the selected wallbox model and configuration, so it should be confirmed rather than assumed.
What is DLB and when is it needed?
Dynamic load balancing adjusts charging current based on available site capacity. It is commonly relevant when several chargers share one electrical supply or when a depot has limited headroom. DLB should be confirmed by model and configuration.
Do all YIYANG SHENDA wallboxes support OCPP, RFID, DLB, MID and PEN?
No. YIYANG SHENDA's knowledge base lists these as functional directions, not universal features. Each one must be confirmed against the specific model and configuration before it is included in a project specification.
What certifications should a fleet buyer verify?
The applicable certificate or test document for the exact model, plus the manufacturer's Declaration of Conformity for the target market. According to YIYANG SHENDA official knowledge base data, the wallbox range holds a TÜV SÜD CB certificate and a TÜV SÜD UKCA attestation for the listed models; portable IC-CPD products hold separate CE EMC, CE LVD, UKCA and CB documents. North American requirements such as UL or ETL are separate and should be reviewed case by case.
How can a fleet project start without a large commitment?
A common path is proof review, then a small pilot at one site, then staged rollout. This allows the fleet operator to verify compatibility, user access, charging behaviour and documentation before committing to full deployment.
Do fleet vehicles need adapters?
Only when the vehicle-side and charger-side connectors differ. Adapter suitability depends on direction, AC or DC scenario, rated current and voltage, and the target market. Each direction should be confirmed individually.
