GR Electric Vehicle Charger FAQ
1. What are the applicable scenarios and multi-vehicle charging capabilities of the GR electric vehicle charger?
The GR electric vehicle charger fits various scenarios seamlessly. It works in highway service areas, urban business district rest stops for quick refuels; fleet charging stations (logistics, ride-hailing) and enterprise parking lots for batch charging via mass deployment; and residential underground garages or private villa parking spots for home use.
For multi-vehicle charging, modular or cluster-managed models support 2-4 concurrent charges. Intelligent load balancing distributes power to avoid grid overload, boosting efficiency.
2. What is the compatibility coverage of the GR electric vehicle charger?
The GR charger boasts full compatibility with all European-standard models. Upholding "barrier-free charging", it supports Type 1/Type 2 interfaces and CCS1/CCS2 DC fast-charging standards via built-in multi-protocol modules, adapting to mainstream brands like Tesla, Volkswagen, BMW and niche models alike.
It also integrates V2G (Vehicle-to-Grid) tech, forming a micro-grid with solar systems and energy storage—realizing "photovoltaic generation → vehicle storage → grid peak regulation" loops to cut costs and advance sustainable energy.
3. What installation support services does the GR electric vehicle charger provide?
GR offers comprehensive installation support: an industrial-grade manual with wiring diagrams, embedding specs and 3D demos; 7×24 remote tech help for wiring/communication issues; on-site surveys and custom plans for large projects to ensure grid compatibility.
4. How to monitor and manage the charging status of the GR electric vehicle charger?
Equipped with OCPP 1.6 JSON/2.0.1 (upgradable to 2.0+) and Ethernet/Bluetooth/Wi-Fi/4G, it enables remote management. Users can monitor via:
① Mobile App (real-time voltage, current, SOC; reservations, fees);
② Web platform (data reports);
③ API integration with fleet systems for multi-site control.
5. What safety protection mechanisms does the GR electric vehicle charger have?
Meeting IEC 61851-1, it has 7 core protections:
- Overcurrent: <50ms response to prevent overheating;
- Over/undervoltage: Auto-shutdown beyond AC 220V/400V±15%;
- Short-circuit: <10ms response via fast fuses;
- Leakage: ≤30mA residual current for safety;
- Over-temperature: Power reduction at >55℃;
- Surge: IEC 61000-4-5 compliant, resisting 4kV/8kV surges.
6. What is the warranty policy for the GR electric vehicle charger?
It includes a 2-year full-unit warranty covering all original components. Faults from quality issues or normal use get free repairs/replacements; unrepairable units are replaced.
For long-term needs, a paid 5-year warranty extension is available, with the same coverage. Exclusions: man-made damage (tampering, impacts), force majeure (lightning, floods) and wear (charging cable aging) – these qualify for paid repairs.
7. What certifications and regulatory compliance tests has the GR electric vehicle charger passed?
The charger holds globally recognized authoritative certifications:
- TUV: Certified to EN 61851-1 (EV conductive charging), ensuring safety and performance;
- CE: Compliant with EU EMC and LVD directives, meeting strict European market standards;
- CB: Accepted by IEC member states worldwide, validating cross-border compliance;
