Product Overview
Tailored for commercial complex parking lots, office buildings, public convenience charging points, and operator light-asset layouts, this charger offers 20kW/30kW/40kW options (200-1000VDC output). With wall-mounted integrated design, it integrates intelligent management, remote O&M, and flexible payment. Compliant with OCPP 1.6J protocol, IP54/IK10 protection, and -30°C~80°C operating temperature, it ensures stable commercial operation. OTA upgrade and FRU diagnostics reduce O&M costs, suitable for commercial charging services.
Key Features
OTA Remote Upgrade: Remote protocol updates and vulnerability fixes without on-site operation.
Intelligent Charging Management: Adjusts current/power based on grid load and BMS feedback, avoiding overload.
Remote Fault Diagnosis: Background query and restart via OCPP 1.6J, reducing on-site maintenance.
Configurable Power: 10kW~40kW adjustable, adapting to grid capacity and scenario needs.
OCPP 1.6J Compatibility: Seamless connection to mainstream operation platforms for order and equipment management.
Optional Payment Methods: RFID (ISO/IEC 14443A/B) and credit card reader for membership/temporary users.
Easy Maintenance: FRU diagnostics and modular design, reducing downtime.
High Protection & Wide Temperature: IP54/IK10 protection, -30°C~80°C adaptability for harsh commercial environments.
7-Inch Touch Screen: Intuitive operation for charging control and parameter query.

Application Scenarios
Commercial Complex Parking Lots: Space-saving design, multiple payment methods, balancing charging speed and energy consumption.
Office Building Charging: Connects to intelligent management systems, RFID/mobile payment, reducing property maintenance.
Public Convenience Charging Points: Rapid deployment without complex civil engineering, adapting to outdoor extreme weather.
Hotel/Scenic Area Charging: Aesthetic design, quiet cooling, optional credit card payment for guests.
Enterprise Park Shared Charging: Configurable power avoids grid overload, easy maintenance for fleet use.
Operator Light-Asset Layout: Low land cost, centralized management via OCPP 1.6J, improving asset utilization.
1. Only as an additional service, not for profit purposes: For scenarios such as hotels/homestays, beauty salons, etc., it is recommended to use a light asset model and deploy a small amount of WZ15L, WZ15W, or WZ17W for charging settlement through local pricing models, in order to provide additional value-added services.
2. Scenarios for small commercial charging stations/shopping mall charging stations: Considering the load capacity of the station area, it is not possible to deploy too many charging positions. WZ05, WZ06, WZ07, WZ08, and other fast charging devices with one machine and two guns can be selected, which are the preferred choices for the renovation of old parking lots. They can be easily deployed and used. If you need a scenario with one machine and multiple positions, you can choose the WZ09 and WZ10 series.
3. Medium to large commercial charging station scenarios: Choose multiple integrated one machine dual gun high-power solutions, such as WZ06, WZ07, WZ08, WZ09, WZ10 series, or a set of WZ12 series, to meet the simultaneous charging of multiple vehicles.
4. Large and ultra large commercial charging scenarios: Choose the WZ12 series, equipped with a large number of fast charging terminals and a small number of liquid cooled charging terminals. Firstly, it can meet the ultra fast charging needs of some high-end car models, demonstrating operational strength and improving reputation. Secondly, it can meet the simultaneous charging needs of many vehicles through a large number of fast charging terminals.
All WZ series products support OTA remote upgrades, which can be carried out through commercial backend pre updates to achieve protocol updates and vulnerability fixes without on-site operations, reducing maintenance costs for commercial operations.
The default length for regular cables is 3.5m, and the entire range supports customized cables of 3-7M length
