Engineered for Indonesia’s tropical climate, grid dynamics, and commercial operational standards.
An authoritative operational guide for commercial real estate developers, fleet operators, public utilities, and EV equipment importers across East Java.
As Indonesia’s second-largest metropolitan area and the primary industrial hub of East Java, Surabaya is undergoing a massive transformation toward electrified transportation. Driven by Presidential Regulation (Perpres) No. 55/2019 and national commitments to achieve net-zero carbon emissions by 2060, the city's commercial and industrial logistics ecosystems are shifting rapidly from internal combustion engine (ICE) fleets to electric light commercial vehicles (e-LCVs), passenger EVs, and electrified two/three-wheelers.
Deploying electric vehicle supply equipment (EVSE) in Surabaya requires an in-depth understanding of local grid realities. The East Java electrical power network, operated by State Electricity Company PLN (Perusahaan Listrik Negara), presents specific 3-phase grid parameters (380V/50Hz) and distinct peak tariff structures. Furthermore, Surabaya’s tropical marine environment—characterized by average annual humidity levels exceeding 80%, ambient operational temperatures soaring to 36°C, and coastal salt mist around Tanjung Perak Port—demands industrial-grade physical enclosure protection (IP65/IK10) and robust thermal management algorithms.
From heavy industrial estates to luxury commercial districts, custom AC charging solutions deliver maximum operational uptime.
Overnight fleet charging for corporate delivery fleets and worker shuttle buses. Modular 11kW/22kW AC wallboxes integrated with Dynamic Load Balancing (DLB) prevent facility peak demand charges on industrial PLN tariffs.
Heavy-duty, IP65-rated anti-corrosion chargers deployed at port container terminals. Designed to resist high humidity, marine salt spray, and extreme dust while supplying reliable Level 2 power to site service vehicles.
Public-facing dual-gun vertical AC charging piles equipped with OCPP 1.6J cloud compliance. Allows mall operators to monetise parking spots via automated QRIS, GoPay, OVO, and credit card digital payment gateways.
Residential Smart Wallboxes for luxury private housing developments in CitraLand and Graha Famili. Enables scheduled off-peak charging (22:00–05:00) via mobile app to lower monthly household electricity expenditure.
Solves local grid limitations through Solar Photovoltaic (PV), Battery Energy Storage Systems (BESS), and Dynamic Load Balancing.
Deploying multi-unit AC charging hubs in Surabaya often faces transformer capacity constraints. Upgrading PLN substation transformers can involve long lead times and high capital expenditure. Tongxing’s proprietary Integrated Photovoltaic-Energy Storage-EV Charging Architecture circumvents grid constraints by managing localized energy creation, storage, and dispatch.
| Performance Metric | Traditional Grid-Direct AC Charging | Tongxing PV-BESS Integrated Solution | Quantifiable Operational Benefit |
|---|---|---|---|
| PV Self-Consumption Rate | 50% (Standard Solar) | 85%+ Integrated Dynamic Tracking | ↑ 70% Increase in clean energy usage |
| Comprehensive Energy Cost | 0.85 USD / kWh (Peak Grid Rate) | 0.62 USD / kWh (Blended Solar/BESS) | ↓ 27% Reduction in operational OPEX |
| Peak Demand Grid Stress | High (Risk of Transformer Overload) | Zero (Battery Peak Shaving Discharges) | Eliminates PLN transformer upgrade fees |
| Annual Carbon Footprint | Baseline Grid Emission Factor | 40% - 60% Carbon Offset | Accelerates ISO 14064 certification |
| Grid Outage Resilience | Immediate Shutdown during Blackout | 72-Hour Continuous Emergency Operation | Uninterrupted commercial operations |
Equipped with dual-core MCU control redundancy, military-grade components, flame-retardant V0-rated enclosures, and Type A + DC 6mA residual current leakage protection (IEC 62955 compliant) to ensure operator safety under tropical monsoon humidity.
Native support for Open Charge Point Protocol allows seamless integration into any localized CPO (Charge Point Operator) platform in Indonesia. Features remote firmware updates (OTA), diagnostic telemetry, and secure API bindings.
Real-time current transformers (CT) continuously measure main building power usage, instantly modulating the charger’s output power (from 32A down to 6A) to prevent tripping total building circuit breakers during peak operating hours.
