Winter is the "True Stress Test" for EV Charging Operations

From December to February, CPOs (Charge Point Operators) in the Northern Hemisphere face their "nightmare season." Statistics show that when temperatures drop below freezing, hardware failure rates rise by an average of 15%, and reports of charging session failures spike. The problem isn't just the maintenance cost. For a shivering customer, a single "failed charging experience" often leads to immediate churn. The biggest risk is that one bad experience can drop customer retention to 0%. Because these situations can happen to anyone, we are sharing the Top 3 Technical Risks that are most fatal in winter, along with a 10-Step Actionable Checklist that your field operations team can apply immediately.

PART 1. The Invisible Profit Killers

Why does the revenue graph dip while OPEX skyrockets only in winter? Here are three technical causes every CPO must understand.

1. The "Coldgate" Phenomenon & Charging Speed Complaints

In winter, 40% of CS tickets are complaints that "charging is too slow." However, in most cases, this is not a charger issue. It is due to the EV's BMS (Battery Management System) forcibly limiting input power to protect the battery at low temperatures.

Action for CPO: You must reduce the cost of unnecessary "Truck Rolls" (dispatching technicians) caused by misdiagnosing this as a device failure. Update your App or Charger UI to display a message: "Charging speed may be limited if battery pre-conditioning is not performed," to educate users and save operational costs.

2. LCD Screen Latency (Ghost Touch)

In environments below -10°C (14°F), liquid crystals in low-cost LCD panels can stiffen, causing "Ghost Touches" or unresponsive screens. A customer trying to touch the screen more than three times with frozen hands will likely give up and leave.

viveEV Insight: To prevent drop-offs at the payment stage even in extreme conditions, industrial-grade panels guaranteed to operate within a wide temperature range (-20°C to 50°C/-4°F to +122°F) are essential.

3. Internal Wire Breaks due to Cable Stiffness

When cables freeze and stiffen, users tend to pull or bend them with more force than usual. This causes more than just external damage; it leads to short circuits in the internal communication lines (CP/PP lines), making charging sessions impossible. This is a fatal factor that instantly drops revenue to zero.

PART 2. The 2025 Winter Readiness Checklist (10-Step)

Share this list with your Field Operations team immediately. A small check can drastically reduce winter downtime.

🔌 Hardware & Visual Inspection

[1] Check for Condensation/Fogging on Exterior & Panels

Check: Look for signs of snow/rain ingress and internal moisture (fogging) due to rapid temperature changes.
Why: Internal condensation is a primary cause of mainboard short circuits.

[2] Test Connector/Cable Temperature & Elasticity

Check: Ensure cables haven't become excessively stiff and check their restoring force when bent.
Why: Stiff cables induce user error and increase the risk of internal disconnection.

[3] Check Connector Terminals for Cleanliness & Oxidation

Check: Inspect pins for corrosion caused by moisture and calcium chloride (road salt) ingress.
Why: This accounts for over 30% of actual causes for charging failures and communication errors.

[4] Inspect Drainage Around the Charger

Check: Ensure water does not pool after heavy snow or rain.
Why: This is an essential safety factor for preventing electric shock and ensuring accessibility.

[5] Check Cable Storage Condition (Cable Holders/Retractors)

Check: Adjust tension and storage to ensure connectors do not drag on snow-covered ground.
Why: This is the most basic method to prevent foreign debris from entering the connector.

📊 Data & Software Inspection

[6] Review Charging Speed Log Data (Last 4 Weeks)

Check: Identify if sudden speed drop patterns appear only on specific devices via back-office data.
Why: You must use data to pre-determine whether it is a mechanical defect or a vehicle Coldgate issue.

[7] Check Voltage Fluctuation & Peak Usage

Check: Monitor voltage instability during times that overlap with increased winter heating demand.
Why: A load balancing strategy is needed to avoid "Demand Charge" bombs from utility companies.

[8] Check Vehicle–Charger Communication Protocols (OCPP/ISO15118)

Check: Look for intermittent heartbeat misses or authentication error patterns at low temperatures.
Why: The stability of the communication module is the core of unmanned operations.

[9] UI/HMI Screen Response Test

Check: Test screen touch response speed and readability during night/low-temperature hours.
Why: You must maintain intuitive response speeds so customers don't waste time in the cold.

📦 Inventory Management

[10] Secure Safety Stock for Spare Parts (Cables, Connectors)

Check: Secure stock for parts with high winter failure rates (Connector guns, LCD modules, etc.).
Why: Immediate replacement upon failure to minimize downtime is key to increasing ROI.

Winter Preparation is the Easiest Way to Boost "Operational Efficiency" and "Customer Trust."
