FAQ for Commercial DC Charger
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.
