Electric Vehicle Supply Equipment (EVSE) charge points, such as the zappi from myenergi, are designed to provide efficient and safe charging for electric vehicles. However, it's important to understand the limitations and design specifications of these devices, especially when considering configurations like daisy chaining. Here, we explain why you cannot daisy chain two zappi charge points together.
Understanding Daisy Chaining
Daisy chaining refers to the practice of connecting multiple devices in a series, where each device is connected to the next in line. While this configuration is common for certain types of electronic equipment, it is not suitable for EVSE charge points for several key reasons.
Design Specifications
- Electrical Load Management
- Power Capacity: Each zappi charge point is designed to handle a specific electrical load. Daisy chaining two charge points would exceed this capacity, leading to potential overloads and creating safety hazards.
- Dedicated Circuitry: zappi is meant to be connected to dedicated electrical circuits. This ensures that the load is managed properly and does not interfere with other devices. Daisy chaining would compromise this setup, increasing the risk of circuit breaker trips and electrical fires.
- Communication Protocols
- Smart Charging Features: The zappi charge point includes advanced features like load balancing and grid communication. These features rely on specific communication protocols that are designed for standalone operation. Daisy chaining two units would disrupt these protocols, causing potential malfunctions and inefficiencies in charging.
- Safety Standards
- Regulatory Compliance: EVSEs must comply with stringent safety standards and regulations. The zappi charge point is tested and certified for single-unit operation. Daisy chaining two units would violate these certifications, making the setup non-compliant and potentially unsafe.
- Fault Isolation: In the event of a fault, each zappi unit is designed to isolate the issue and prevent it from affecting other parts of the electrical system. Daisy chaining compromises this isolation, increasing the risk of widespread electrical failures.
Practical Considerations
- Installation Complexity
- Wiring and Configuration: Proper installation of EVSEs involves precise wiring and configuration. Daisy chaining would complicate the installation process, leading to potential errors and increased installation costs.
- Maintenance and Troubleshooting: Identifying and fixing issues becomes significantly more difficult with a daisy-chained setup. Each unit's interdependence would complicate troubleshooting and maintenance efforts.
- Performance and Efficiency
- Optimal Charging: The zappi charge point is designed to provide optimal charging performance for electric vehicles. Daisy chaining could lead to reduced charging efficiency, longer charging times, and increased wear on the charge points
Conclusion
While daisy chaining might seem like a convenient solution for expanding charging capabilities, it is not feasible or safe for zappi charge points. The design specifications, safety standards, and practical considerations all point to the necessity of using each zappi unit independently on its dedicated circuit. For those looking to install multiple EVSE charge points zappi sadly isn't an option for you.
By adhering to these guidelines, users can enjoy the full benefits of their zappi charge points while maintaining the highest standards of safety and performance.
