Jawaban Cepat: Di Mana SPD Harus Digunakan dalam Proyek Pengisian EV?
Untuk sebagian besar proyek pengisian EV komersial atau publik, pemilihan SPD bukanlah keputusan satu perangkat. Kontraktor harus memeriksa setiap titik perlindungan dari pasokan daya masuk ke pengisi daya, jalur komunikasi, dan sistem pemantauan.
| Titik Perlindungan | Arah SPD yang Direkomendasikan | Arti Kontraktor |
|---|---|---|
| Papan distribusi masuk utama | Gunakan SPD Tipe 1+2 ketika ada perlindungan petir eksternal, pasokan overhead, atau paparan petir tinggi. Gunakan SPD Tipe 2 untuk kondisi pasokan dengan risiko lebih rendah. | Ini adalah tahap perlindungan pertama untuk pasokan daya pengisian EV. |
| Papan distribusi sub dekat pengisi daya | Gunakan SPD Tipe 2, dikordinasikan dengan SPD hulu. | Ini mengurangi lonjakan residual sebelum mencapai input pengisi daya. |
| Input AC pengisi daya EV | Pilih SPD AC fase tunggal atau tiga fase berdasarkan tegangan sistem, sistem pentanahan, konfigurasi makhluk, dan posisi pemasangan. | Ini melindungi elektronik pengisi daya, modul daya, pengukuran, dan sirkuit kontrol dari lonjakan tegangan transien. |
| Bagian pengisi daya cepat DC | Periksa persyaratan sisi DC kasus per kasus sesuai dengan arsitektur pengisi daya, tegangan DC, desain isolasi, dan persetujuan pabrikan. | Jangan gunakan SPD DC PV secara membabi buta sebagai pengganti universal untuk pengisi daya cepat DC. |
| Jalur komunikasi dan kontrol | Gunakan SPD sinyal yang sesuai untuk Ethernet yang terbuka, RS485, pengukuran, pemantauan, atau kabel terkait OCPP. | Lonjakan dapat masuk melalui jalur data, tidak hanya melalui jalur daya AC. |
| Sistem alarm jarak jauh dan pemeliharaan | Gunakan model SPD dengan kontak sinyal jarak jauh ketika stasiun memiliki beberapa pengisi daya atau memerlukan pemantauan terpusat. | Tim pemeliharaan dapat menemukan modul SPD yang gagal dengan cepat tanpa membuka setiap kabinet. |
Aturan sederhana: lindungi pasokan yang masuk terlebih dahulu, kemudian lindungi panel hilir dan input pengisi daya. Untuk proyek luar ruangan atau publik, juga periksa jalur sinyal, pentanahan, dan persyaratan alarm jarak jauh sebelum memesan.
Apakah Stasiun Pengisian EV Membutuhkan Perlindungan Lonjakan?
Yes, EV charging stations normally need surge protection, especially for public charging points, outdoor chargers, commercial parking areas, fleet charging stations, and DC fast charger projects. EV chargers contain sensitive electronics, power conversion components, communication circuits, metering modules, and control boards.
Surge risk can come from nearby lightning activity, switching operations in the grid, long cable routes, poor bonding, overhead supply lines, and exposed communication wiring. A surge may not destroy the whole charger immediately, but it can damage control boards, communication ports, power modules, or monitoring circuits.
Penting: The correct SPD arrangement depends on local electrical code, lightning exposure, supply method, earthing system, charger type, distance between panels and chargers, and whether the site has an external lightning protection system.
Posisi Pemasangan SPD di Stasiun Pengisian EV
A reliable EV charging station should be checked as a system. The SPD should not be selected only by looking at the charger nameplate. Contractors should review where the surge may enter and how the surge current can be discharged safely.
Recommended SPD protection architecture for EV charging station projects.
Papan Distribusi Utama
This is the first protection stage for the EV charging supply. Use Type 1+2 when lightning current risk is expected, or Type 2 for lower-risk incoming supply.
Papan Distribusi Sub
When chargers are supplied from a local sub-panel, a downstream Type 2 SPD helps reduce residual surge before it reaches the charger input.
AC Input of Charger
Select the SPD by AC system voltage, pole configuration, earthing system, discharge current rating, and remote signal requirement.
Signal and Monitoring Lines
Ethernet, RS485, metering, billing, or OCPP-related communication lines may need signal SPD, especially when cables run outdoors or between cabinets.
Standar dan Aturan Pemasangan yang Harus Diketahui Kontraktor
In IEC-based EVSE projects, surge protection is often checked together with the electrical installation rules for EV charging equipment and the SPD product standard for low-voltage AC systems. This does not mean every site uses the same SPD arrangement. It means the contractor should confirm the site condition before choosing the SPD type.
| Reference Area | What It Means for EV Charging SPD Selection | Contractor Action |
|---|---|---|
| EVSE electrical installation rules | Public or commercial EVSE installations may require transient overvoltage protection depending on installation condition and local code. | Check whether the EVSE supply switchboard, sub-panel, or charger cabinet needs additional SPD protection. |
| IEC 61643-11 for AC SPD | AC low-voltage SPDs should be selected and documented according to the relevant SPD product standard and required certification scope. | Confirm Type 1+2 or Type 2, Uc, In, Imax, Iimp, Up, pole configuration, and certificate requirement. |
| Distance between upstream SPD and charger | When the charger is far from the upstream protection point, the downstream equipment may still see high residual surge stress. | Consider an additional Type 2 SPD near the EVSE or local sub-distribution board, especially for long feeder cable routes. |
| External lightning protection system or overhead supply | These conditions increase the need to consider lightning current discharge at the incoming side. | Review Type 1+2 SPD or coordinated Type 1 + Type 2 protection at the main incoming position. |
| Local inspection and project specification | Many EV charging projects have country-specific code, utility requirement, or consultant specification. | Ask the customer for the project specification before confirming the final SPD model. |
Practical rule for buyers: do not ask only for “EV charger SPD price”. Send the single-line diagram, installation position, charger distance, earthing system, and lightning exposure first. These details decide whether the project needs Type 1+2, Type 2, signal SPD, or remote alarm options.
Tipe 1+2 vs Tipe 2 SPD untuk Stasiun Pengisian EV
The choice between Type 1+2 and Type 2 SPD should follow the site risk and installation position. Do not choose Type 1+2 only because it sounds stronger. Also do not use Type 2 everywhere without checking lightning exposure and the upstream protection design.
Type 1+2 SPD and Type 2 SPD selection logic for EV charger supply panels.
| Project Situation | Better SPD Direction | Why It Matters |
|---|---|---|
| Building has external lightning protection system | Type 1+2 SPD at the main board or incoming EV supply panel | The main board may need to discharge lightning current and reduce residual surge for downstream equipment. |
| Outdoor charging station with high lightning exposure | Type 1+2 SPD or coordinated Type 1 + Type 2 protection | Outdoor chargers and long cable runs are more exposed to lightning-induced transients. |
| Indoor commercial AC charger supplied from protected board | Tipe 2 SPD | Type 2 SPD is commonly used for induced surge and switching surge protection in distribution boards. |
| Charger is far from the main panel | Add Type 2 SPD near the charger or local sub-distribution board | Long feeder cables can increase residual surge stress at the EVSE side. |
| Signal cable runs outdoors or between cabinets | Signal SPD for the correct communication interface | Power SPD cannot protect low-voltage data lines correctly. |
For EV charging projects, the SPD type should be selected together with the protection location. A main incoming board, sub-panel, charger cabinet, and signal cabinet may need different protection devices.
Pemilihan SPD Input AC untuk Pengisi EV
For AC chargers and the AC input of DC fast chargers, the SPD should match the real power supply system. Contractors and panel builders should not order by “EV charger SPD” only. The supplier needs the electrical system information to recommend the correct model.
Key AC SPD Parameters to Confirm
- Tegangan sistem: 230V, 400V, 415V, or other local supply voltage.
- Phase type: single-phase or three-phase charger supply.
- Earthing system: TN-S, TN-C-S, TT, IT, or project-specific system.
- Jenis SPD: Type 1+2 or Type 2, depending on installation position and lightning risk.
- Konfigurasi kutub: 1P+N, 2P, 3P, 4P, 3P+N, or other arrangement required by the panel.
- Uc / MCOV: must match the continuous operating voltage of the system.
- In / Imax: nominal and maximum discharge current for Type 2 SPD selection.
- Iimp: impulse current rating for Type 1 or Type 1+2 SPD.
- Up: voltage protection level suitable for the charger and downstream electronics.
- Remote alarm: dry contact / remote signal option for maintenance monitoring.

Perlindungan Lonjakan Pengisi Cepat DC: Apa yang Harus Diperiksa?
DC fast chargers need special attention because they include AC input, power conversion, DC output, control circuits, communication ports, and sometimes long cable routes. The AC input side normally follows AC low-voltage SPD selection logic. The DC side should be reviewed separately.
Do not blindly use a PV DC SPD for a DC fast charger. PV strings and EV DC fast chargers are different applications. DC-side protection depends on charger output voltage, converter architecture, insulation coordination, cable routing, enclosure design, and manufacturer approval.
Before selecting DC-side protection, confirm:
- DC output voltage range of the charger.
- Whether the DC side is accessible for external SPD installation.
- Internal converter and isolation design.
- Manufacturer’s approved protection scheme.
- Applicable project standard and local inspection requirement.
- Whether the risk is at AC input, DC output cable, communication line, or cabinet grounding.
Perlindungan Lonjakan Jalur Sinyal untuk Stasiun Pengisian EV
EV charging stations are not only power devices. They often connect to payment systems, load management systems, backend platforms, energy meters, PLCs, and monitoring devices. Surges can enter through these signal lines.
For signal protection selection, see: RS485 SPD Wiring and Selection Guide.
Titik Penting Pembumian dan Pengikatan yang Harus Dikonfirmasi Kontraktor
An SPD needs a reliable discharge path. If the earthing and bonding design is poor, the SPD may be installed in the cabinet but still fail to protect the EV charger effectively.
- Earthing system: TN-S, TN-C-S, TT, IT, or project-specific arrangement.
- PE conductor routing from main board to EVSE cabinet.
- Connection between metal charger enclosure and protective earth.
- Equipotential bonding between cabinets, metal structures, and parking area equipment.
- Earthing rod requirement for outdoor or independent charging points.
- Shortest practical SPD connection length to reduce residual voltage.
Alarm Jauh, Indikator Visual, dan Penggantian Pemeliharaan
EV charging stations usually have multiple chargers. In this situation, SPD maintenance should not depend only on someone opening every cabinet and checking the indicator window manually.
For remote alarm wiring, see: Bagaimana Menghubungkan Kontak Alarm Jarak Jauh SPD ke PLC atau Sistem Pemantauan.
