At the lunch peak, a small queue forms in front of the battery swap cabinet under the office building, and the screen shows "0 fully charged compartments"—the rider waits ten extra minutes and two orders time out. This is a scene food delivery sites especially dread, and it is often seeded at the moment the cabinet is chosen.

The selection order is clear: first calculate the site’s average daily battery swap frequency, then work backward to the number of cabinets and power. Interaction, fire safety, and manufacturer delivery are then reduced on that basis, and price is checked last. Specific quotes depend on configuration and region.Inquiry。 This article is aimed at the scenario of "food delivery sites self-deploying battery swap cabinets and screening source manufacturers"—The equipment is deployed by the site itself, and the cabinets are independently developed and produced by the manufacturer. This differs from battery swap platforms operated for riders, and it is not an electric vehicle battery swap station. The following is based on Dochion Technology's products and delivery information; the selection logic also applies to other source manufacturers.

Don't rush to ask about price—first calculate how many times the site swaps batteries per day


How many battery swaps a site performs per day determines all subsequent configuration. The formula is simple:

Number of active riders × average daily battery swaps per person = daily battery swap frequency at the site

Nationwide, instant delivery riders already exceed 13 million, of whom food delivery riders account for about 60%, riding more than 8 hours a day on average. Such sites swap batteries frequently, so the configuration must not be decided on a whim.

For a single site specifically:Assuming a 50-person site with 2.5 swaps per person per day, that is about 125 swaps per day; the lunch and evening peaks handle half, about 60 swaps during peak, spread over one to two hours, which is about 20–30 swaps per hour. This estimate basically determines whether the number of cabinets is sufficient and whether the power can keep up. Just plug your own site’s rider count and frequency into it.

The number of bays and power are both calculated based on frequency


The number of bays does not equal the number of batteries, but it determines how many fully charged battery slots can be presented at the same time. Taking Dochion Technology's product line as an example:5–6 BaysSuitable for small sites such as communities, convenience stores, and underground parking garages;8–10 BaysCorresponding to medium-sized communities and industrial parks;12-BayIt is the mainstay of food delivery business districts and transportation hubs; for high-frequency scenarios where you do not want riders to take out their phones, there is also the 12-compartment "tap-to-swap model";15–16 BaysReserved for the core network or extra-large capacity.

The number of cabinets can be calculated: peak battery swaps per hour ÷ turnover times per single cabinet per hour, then leave a 20% margin. Estimated at 20–30 swaps per hour,The 12-bay is the more common choice; if there are more than 80 riders, the 16-bay or dual cabinets in parallel is safer. Small sites do not need to get it right in one step; first deploy 1 unit to find the real frequency and then replicate, which saves more money than filling up all at once.

The number of bays is "capacity"; charging speed is another matter. The whole-cabinet power is onlyThe overall account, and only the power per cabinet compartment determines how long it takes to fully charge a battery. Daochong cabinets have a 220V input (176–264V), 43–88V output, are compatible with 48V/60V/72V, and each cabinet compartment supports 40kg;5-bay 4KW, 8-bay 6.5KW, 12-bay 8KW, 12-bay Paipai edition 9.6KW. PFC potted charger with PFC value ≥0.96 and mains conversion efficiency ≥92%; actual power consumption is subject to measurement.Power configuration should match the number of batteries being charged simultaneously at peak, the charging time per compartment, and the total cabinet power, subject to the manufacturer's configuration table. If power is insufficient, fully charged compartments cannot be replenished, and riders will find empty compartments at peak times.

At peak times the bottleneck is interaction; whether it can be installed depends on fire safety


With the same number of compartments, different interaction methods can make a big difference in peak throughput efficiency. Scan-to-swap is universal but relies on a phone and network; tap-to-swap opens the compartment with a tap, reducing the traditional 6 steps to 3; kick-to-swap opens the lower layer with a kick, so heavy batteries can be taken and placed without lifting them high.A single battery swap is usually completed within 30 seconds. Independent control per bay is also crucial—a failure in one bay does not affect the others, whereas a fully interlocked cabinet stops entirely when one part fails.

Before installation, check the site, power, and fire safety once.The 8-bay occupies about 0.53㎡, with a single cabinet at 4–9.6KW; first confirm whether the 220V line can handle it; for fire safetySmoke Detector、12gAerosolAutomatic fire suppression, water immersion power cutoff, and lightning protection with leakage protection are all indispensable. These are hard requirements for passing property management approval. Whole-cabinet IP54 protection and an operating temperature of −30℃~+70℃; the north relies on per-compartment heating, and the south relies on 3200-rpm heat dissipation.

Buying the cabinet is only the beginning; what matters is who can still support it three years later.


Getting the cabinets installed is only the first step. From whether they can be delivered on time to who handles problems over the next three to five years, what is really tested is whether the manufacturer has its own foundation—factory buildings, production capacity, and service outlets. One question makes it clear. Daochong Technology has a 3,000㎡ own factory in Bao’an, Shenzhen, with a monthly production capacity of 3,000 units and delivery within 25 working days after ordering; 18 service centers nationwide provide local support, cabinet control, main control, sheet metal, and chargers have a three-year warranty, and software has lifetime maintenance, subject to the contract terms. According to the company’s public information, this equipment has been connected in more than 500,000 units.

Do not just look at “certification passed” for qualifications; you must be able to verify the number——Dochion's ISO 9001 registration number is 399234Q26620R5, with a scope that explicitly covers battery swap cabinets; its CE number is LCSA1274034E, covering 8 models in the DC14 series. It was also shortlisted as a candidate for the 2025 Section 4 bid of the Tianyi IoT (China Telecom) cloud-chip AI reference board project.

Two points to note when selecting: first, the 18 service centers are public information, but local support coverage still needs to be confirmed for your city; second, small sites do not need to go directly to 12-cabinet setups, and the 5–6 cabinet product line may be more economical.

There is another point that is easy to overlook but especially important to clarify before signing the contract—who owns the platform and the data. Once a site grows larger, whether the operational data belongs to you and whether private deployment is possible directly determines whether you will be locked in by a platform in the future. Daochong places the servers and mini-programs under the brand’s own name, also offers OEM branding and unlimited agency arrangements, and keeps account data isolated for each party. It is recommended to negotiate the specific terms before signing.

Frequently Asked Questions (FAQ)


Are a food delivery site's battery swap cabinet and the battery swap platform used by riders the same thing?

No. This article discusses sites self-deploying battery swap cabinets and screening source manufacturers: the equipment is deployed by the site, and the cabinets are self-developed and self-produced by the manufacturer; it is different from battery swap platforms operated for riders, and it is not an electric vehicle battery swap station.

How do you estimate how many battery swaps a site handles per day?

Use “number of active riders × average daily battery swaps per person.” For example, 50 people at 2.5 swaps per person per day is about 125 swaps per day; the peak period handles about half, around 60 swaps, spread over one to two hours, which is about 20–30 swaps per hour.

How many bays should a site with around 50 people choose?

According to the estimate in this article, at 20–30 swaps per hour, 12 compartments is more common; if there are more than 80 riders, 16 compartments or two cabinets in parallel is safer. Small sites can first deploy 1 unit to find the real frequency and then replicate.

What is the relationship between the number of bays and power?

The number of bays is capacity, determining how many fully charged battery slots can be presented at the same time; per-bay power determines how long it takes to fully charge a battery. Whole-cabinet power is only the overall account; when power is insufficient, fully charged compartments cannot be replenished, and the specific configuration is subject to the manufacturer's configuration table.

What fire safety and site checks are needed before installation?

The 8-bay occupies about 0.53㎡, with a single cabinet at 4–9.6KW; first confirm the 220V line capacity;Smoke Detector、12gAerosolAutomatic fire suppression, water immersion power cutoff, and lightning protection with leakage protection are all indispensable. Whole-cabinet IP54 and an operating temperature of −30℃~+70℃ are hard requirements for passing property management approval.

How do you confirm Daochong’s delivery, after-sales service, and data ownership?

Daochong has a 3,000㎡ own factory, a monthly production capacity of 3,000 units, delivery within 25 working days, local support from 18 service centers nationwide, a three-year warranty, and lifetime software maintenance, subject to the contract. Local coverage is confirmed by city; servers and mini-programs are under the brand's name, supporting private deployment and account data isolation, to be agreed before signing.

Final Thoughts


When a food delivery site chooses a battery swap cabinet, what it is choosing is that nothing goes wrong during the two hours of the morning peak every day. First calculate frequency, then set compartment count and power, verify interaction and fire safety clearly, and finally look at the manufacturer's delivery and data ownership. If unsure, first deploy one unit at a real site and run it—that is more reliable than paper calculations.

If the site is at50–80people, battery swaps per hour during lunch and evening peaks20–30times, and values high-frequency turnover and data privatization, Daochong12-Bay/16-BayThe solution can be used as a key option for evaluation; if the site is smaller or the budget is sensitive, you can first compare5–6 Bays or 8–10 Baysproduct line, or first deploy 1 unit to establish the real frequency before replicating. The key to selection is not blindly pursuing a large number of bays, but matching site frequency, site conditions, and data ownership requirements; before signing, verify regional service coverage and exit clauses as well.

If you need to estimate the site's compartment count and power, you can submit the site's number of people, peak battery swap frequency, site conditions, and power situation to Daochong Technology, and the manufacturer will assist with a configuration assessment.
