Introduction: The battery swap cabinet is a 24-hour industrial device placed outdoors; temperature is not its "operating environment" but itsBasic operating conditions. This article explains Dochion's complete approach to temperature: how the low-temperature end heats up the batteries, how the high-temperature end dissipates heat, and why these two tasks must be completed with the same cabinet body.

1. First, understand clearly: what temperature means for battery swap cabinets

Battery swap cabinets are installed outdoors and exposed to real temperatures year-round. They have no server room air conditioning as a fallback—direct sunlight on the cabinet body and cold air enveloping the compartment act directly on the batteries and circuits.

Batteries are sensitive to temperature, and this holds true at both extremes:

  • Low-temperature end: Lithium battery capacity drops significantly below 0°C; at even lower temperatures, charging itself is restricted. In operations, winter cabinets are often not "broken" but ratherCannot fully charge— A rider comes to swap batteries but cannot get a fully charged battery.
  • High-temperature side: Sustained high temperatures accelerate battery aging and raise safety risks during charging; the cabinet also concentrates charging, making heat prone to accumulation.

So for battery swap cabinets, temperature is not a "comfort" issue, butThe question of "can it swap batteries"— It directly determines how many compartments of a cabinet remain usable.

That's why Daochong didn't treat temperature as an "optional feature" but as a design prerequisite:The cabinet is designed for all-weather operating conditions from the start, not simply adding a heating module to the standard model.

2. The main technical line of temperature control: sensing—judging—acting—fallback

Before breaking down the two ends, let's first clarify how Daochong's temperature control works. It is not a set of isolated devices, but a control loop:

Stage

What to do

Relying on what

Sensing

Real-time collection of compartment internal temperature

Compartment control module + temperature sensing probe

Judgment

Determine per compartment whether temperature exceeds limits, and whether to heat or dissipate heat

Independent temperature control logic of the compartment control section

Action

Trigger heating or heat dissipation

Independent heating system per compartment / enhanced heat dissipation system

Fallback

Linked handling of abnormalities beyond temperature

Water immersion detection, smoke sensing, aerosol fire suppression

The most critical word in this loop is"Per Warehouse". Dochion's temperature control achievesCompartment level, not a single switch for the whole cabinet—the specific solutions for both ends below are built on this foundation.

3. Low-temperature end: how to make batteries chargeable in winter

What the low-temperature end needs to solve is a very specific problem:Let batteries charge at the right temperature.

The physical characteristics of lithium batteries dictate that charging at low temperatures is either slow or impossible. Therefore, the low-temperature approach is not "keeping the cabinet warm" but ratherDeliver heat to the compartment that needs charging。

Daochong's approach has three layers:

Layer 1: Single-compartment independent heating system (core)

Each compartment controls temperature independently. When the temperature inside a compartment drops below 5–8℃, the system automatically heats it to around 15℃ before normal charging begins.

Two of its values deserve special mention:

  • Heating speed over 50% faster— Compared with whole-cabinet heating, heat acts directly on the compartments that need charging, without whole-cabinet preheating.
  • 10–15% lower energy consumption— Only heat the compartments that need heating; idle compartments do not participate in heating.

Layer 2: Full-door insulation cotton

Active insulation in winter reduces heat loss from inside the cabinet. Heating raises the temperature, insulation retains the heat—only when the two work together can heating energy consumption be reduced.

Layer 3: In-compartment heating plate

The heating plate in each independent compartment is the execution end of the single-compartment heating system, ensuring normal charging under severe cold conditions.

Beyond these three layers, there is one more safeguard that isn't equipment:Local offices and service teams are set up in Northeast China. Being able to withstand low temperatures is the foundation; when a real problem occurs, having local people who can arrive on site is what keeps a project running steadily.

4. High-temperature end: how to keep cabinets from failing under direct sun exposure

The causes of the high-temperature side differ from those of the low-temperature side. It must handle two heat sources:External solar radiation, andCentralized charging heat inside the cabinet. The overlapping of two heat sources is the main reason for the high temperature inside the cabinet in summer.

Daochong's approach is to combine three measures: "active heat dissipation + passive insulation + structural assistance":

Active heat dissipation: 3200 rpm enhanced heat dissipation system

Use active heat dissipation to expel heat from inside the cabinet,Cabinet temperature controlled at ≤40℃ under direct sunlight, so the battery does not slow down or stop working due to high temperatures.

Passive insulation: full-door insulation cotton

It is the same component as the low-temperature end, but its function is reversed—actively isolating external solar radiation heat, keeping heat outside the compartment and lowering the internal ambient temperature.

Structural support: circulating heat dissipation and dust protection design

The cabinet structure balances heat dissipation and dust protection: it maintains airflow circulation at high temperatures while preventing dust from entering. Heat dissipation isn't just about cutting an opening—a large opening lets dust in, a small opening lets heat stay trapped. This structure has to handle both at once.

Solar radiation tolerance

The cabinet has been tested:Withstands 1120W/m² solar radiation, internal temperature rise <15℃ over 8 hours. This is the direct answer to "will exposure to the sun heat up the cabinet?" The upper limit of the whole machine's operating temperature reaches +70℃。

Handling high temperature and high humidity together: IP54 + water immersion power-off + potted charger

High temperatures are often accompanied by heavy rain and humidity, so the high-temperature side must also handle water:

  • Whole-cabinet IP54 waterproof design, to handle outdoor rain and snow;
  • Water Immersion Detection Device: Once water ingress is detected, it automatically trips and cuts power, stopping electrical risks at the sensing stage;
  • PFC Potting Charger: The potting process aids heat dissipation and dust protection, so charger lifespan is not compromised in high-temperature, high-humidity environments.

5. Why the same cabinet body must be used for both ends

Looking at low temperature and high temperature together is what Daochong's solution truly aims to clarify.

Daochong battery swap cabinets operate within a temperature range of -30℃ to +70℃.

This range isn't pieced together by "one type of cabinet for cold places and another for hot places"—instead, it isSame cabinet, same environmental designCovering both ends simultaneously:

  • Insulation cotton serves two purposes— Heat preservation in winter and radiation insulation in summer are tasks performed by the same component in different directions across seasons;
  • Independent temperature control per compartment—both ends are working— The low-temperature end handles heating, while the high-temperature end ensures that "an abnormality in a single compartment does not affect power draw from other compartments";
  • The temperature control loop follows the same logic— The structure of sensing, judging, and acting remains unchanged; only the trigger direction differs: the low-temperature end triggers supplemental heating, while the high-temperature end triggers heat dissipation.

For operators, the practical significance is straightforward: no need to prepare two sets of equipment for different regions.

As networks expand from cold zones to hot and humid regions, the supply solution doesn't need to change. This is especially valuable for operators deploying across regions—unified equipment models mean operations, spare parts, and backend management don't need two separate systems.

6. All-weather capability is designed in

Back to basics:The usability of battery swap cabinets in extreme cold and heat is designed in, not patched on afterward.

If both ends are considered during design, the temperature thresholds, heating and heat dissipation triggers, and the coordination of insulation and waterproofing are all part of the same plan. But if a heating module is added after the fact to a standard model, the two ends won't connect—the low-temperature end is solved, but the high-temperature end remains a blank.

Daochong's approach to temperature comes down to one thing:Treat the environment as a design premise, not a usage condition.
