FAQ for Commercial Integrated Rectifier Stack
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.
The entire system supports intelligent power regulation, which can dynamically allocate power based on grid load and battery status, avoiding grid overload and reducing operating costs.
Peak efficiency ≥ 96%; The power factor is all>0.98, with low energy loss.
Simultaneous charging start-ups for 12 vehicles generate massive instantaneous power spikes. [Solution]: Integration of Dynamic Power Pool Allocation algorithms. [Physical Action]: The CPU captures real-time BMS power requests from 12 terminals and executes millisecond-level dynamic partitioning within the 1200kW total envelope. This physical limit-locking ensures grid-side current stability, strictly adhering to ISO 15118 flexibility mandates.
Under 4000A operation, even minimal contact resistance generates significant Joule heating (I²R). [Redline Process]: We utilize high-conductivity T2 copper busbars with full nickel/silver plating. [Proof-of-Physics]: Thermal simulations at 55°C full-load show busbar temperature rise is restricted within 45K, physically preventing insulation support softening or short-circuit failures caused by localized hotspots.
Large-capacity bus batteries (200kWh+) result in excessive downtime with standard chargers. [Implementation]: Utilization of the Split Rectifier Center architecture. [Physical Benefit]: The WZ12Z can route the full 1200kW capacity to selected heavy-duty terminals, providing up to 400A per gun. This physically compresses 10%-80% charging time to within 30 minutes, directly optimizing fleet SAIFI reliability and operational throughput.
High temperatures exponentially shorten the lifespan of electrolytic capacitors and IGBT modules. [Self-healing Strategy]: Integrated Thermal-linked intelligent power derating. [Physical Action]: When intake air sensors exceed 50°C, the system automatically smooths down output by 10%. This physics-based protection actively restricts thermal accumulation, ensuring semiconductors remain within safe Junction Temperatures (Tj), reducing lifecycle TCO by 30%.
