Power & Electrical

The electrical system is the energy backbone of a mobile habitat. This page shows the architecture from charging sources to storage, distribution, conversion, protection and monitoring, then links each layer to the MHS component and guide records that explain it.

System architecture

This is a conceptual architecture, not an installation wiring diagram. Exact cable sizes, protection devices, charging limits and grounding depend on the selected equipment and vehicle.

Monitoring sits across the architecture rather than in the power path: shunts, chargers, inverter/chargers and gateways report energy flow and device state without replacing hardwired protection.

What the system has to do

  • Accept energy from the vehicle, solar and shore-power sources that are actually installed.
  • Store energy in the house battery within the battery and BMS operating limits.
  • Distribute DC power with branch protection and service isolation.
  • Convert DC to AC when an inverter is part of the camper architecture.
  • Expose enough monitoring to understand battery state and charging behaviour.

Dometic CFX3-25：用于驾驶和露营的冰箱

为什么容积只是选择的一部分，制冷如何使用电池能量，以及在安装前需要检查什么。

Overview

为什么使用压缩机制冷箱？

Dometic CFX3-25 是便携式压缩机冰箱或冷冻冷藏箱，具体取决于其支持的模式。它从储藏室移除热量，并将热量释放到外部。因此，内部低温只是过程的一半：设备需要将热量排放到周围环境中。

便携式结构便于出行，但并不意味着行驶时可以让设备处于未固定状态。位置、固定方式和箱盖开启空间都应纳入露营舱布局规划。

本文涵盖的型号

标称总容积：25 L。规定的电源输入：12/24 V DC 和 AC。隔间：单区。制冷类型：压缩机。预期安装方式：便携式车辆/RV设备。

容积有助于估算容量，但不能说明隔间形状。高瓶、食品容器和篮筐对空间的使用方式不同。区域电源要求和准确的部件识别同样重要；类似产品的信息不能自动替代。

单区、双区和附加功能

MHS 说明。一个可调温隔间不等同于两个独立控制的区域。如需同时储存冷藏和冷冻食品，请检查实际布局。DZ 和 IM 的描述不应被未经解释的笼统冷冻能力声明所替代。

相关版本上的制冰等额外功能，并不能证明设备具有两个完整的温度区域。在比较产品前，设想正常的食品装载量和所需温度。

为什么电流会随时间变化

压缩机会根据需要运行，而不一定持续消耗恒定电流。平均消耗取决于环境温度、设定点、食品初始温度、开启频率和散热情况。

MHS 说明。以一天内 20 W 的示例平均值为例，代表 480 W小时。这只是将功率换算为能量；它不是该型号的实际消耗量。真实的续航计算需要其声明的测试条件或在预期安装环境中的测量结果。

装入温热食品

制冷箱必须冷却其中的内容物以及空气。达到显示温度并不能证明每件新装入的物品都已达到该温度。请遵循允许的装载和操作指南。

MHS 说明。出发前准备好制冷箱和食品可能会改变最初几小时的需求，但不能据此为每次行程确定一个固定节省量。初始条件各不相同。应观察每日消耗量，而不要根据一分钟的运行情况得出结论。

保持散热通道畅通

移除的热量必须排出周围空间。家具或物品堵塞设备通风口会使运行条件恶化。所需间隙应以具体产品的安装说明为准。

使用滑动平台时，应在整个移动范围内检查电缆，并确保隔间关闭时不会夹住电缆。连接不应仅仅因为在一个位置能够工作就一直处于受拉状态。应考虑道路移动和振动。

电源和电池保护

支持的电源以及保护模式必须适合实际电池和电路。长电缆上的电压降可能使制冷箱处的条件不同于电池处的读数。

反复关机并不是降低所有保护阈值的理由。首先检查电源、连接器、警告信息和运行条件。制冷箱的保护功能不能替代整套生活电池或启动电池保护配置，也不能保证每个电路都有足够的启动储备。

保养和存放

清洁或维修前，请遵循安全隔离说明。不要使用尖锐物体损坏内部表面来加快除霜，也不要改动制冷回路。存放后，检查密封件、清洁状况和畅通的散热通道。

MHS 说明。使用预期的电源、安装位置和正常食品装载量，在长途旅行前测试制冷箱。与在工作台上短暂给空柜通电相比，这更能说明其适用性。

关键要点

应根据食品、温度模式和安装条件选择制冷设备，而不能只看升数。随时间使用的能量决定续航能力；电源、固定方式和散热支持可靠运行。

Field evidence belongs to the product record.

A journey is useful when it records what actually happened: distance, weather, road mix, failures, repairs, autonomy and the exact vehicle/camper combination. MHS keeps those observations linked instead of turning them into disconnected travel stories.

MHS Match · BETA

Find the habitat that fits your use

MHS Match first removes modules that conflict with your hard requirements. It then compares the remaining products against your travel profile and priorities. MHS Score and Match Score are intentionally separate.

Matching logic
1Hard compatibility filters
2Must-have requirements
3Weighted personal fit
4Diverse 3–5 model shortlist

Vehicle compatibility

These answers create hard filters. A product that cannot fit the selected vehicle class or installation type is removed before scoring.

Step 1 of 4

How will you use it?

These inputs describe the operating environment and living profile. They affect Match Score, not the product’s MHS Score.

Step 2 of 4

Must have or just preferred?

A Must-have is a hard filter. Prefer affects the Match Score. Doesn’t matter is ignored.

Step 3 of 4
Four-season heating
Internal shower

MHS / Reliability Research
MHS INCIDENT EVIDENCE

Reliability starts with evidence, not a ranking.

MHS is building a model-specific record of real failures, repairs and field incidents. The current phase measures evidence coverage and exposure. It does not name a “most reliable” camper before the data are comparable.

Current model coverage – / –
Loading verified incident evidence…
Verified incident cases–Distinct cases. A failure and its repair remain one case.
Incident source URLs–Unique public URLs supporting current-model incident cases.
Technical cases–Camper system, supplier component or unknown technical origin.
Failure / repair rows–Event rows in the journal; not the same as independent incidents.
Data collection phase

What the current numbers mean

Coverage tells us where MHS has verified incident evidence. It does not tell us which model is more reliable.

One problem = one incident case

If a component fails and is later repaired, MHS links those records to the same incident case instead of counting two failures. This prevents repair documentation from artificially worsening a model’s record.

The public case count is therefore intentionally lower than the number of failure / repair event rows.

Not every incident is a reliability penalty

Physical damage caused by an external event or by user operation can be useful field evidence, but it should not reduce technical reliability.

Technical
–
External damage
–
User operation
–

Evidence acceptance rules

The model identity and the incident itself must both be supported by the source.

Accepted

  • Exact camper model is identifiable from the source.
  • A concrete failure, repair or physical incident is described.
  • A public source URL can be reopened and checked.
  • Model year is retained when known, especially for long-running model names.
  • Official recalls count only when applicability to the exact model is explicit.

Rejected

  • General complaints about a brand or product family.
  • Problems reported for a neighboring model or uncertain subtype.
  • Normal maintenance, preferences or design annoyances without a failure.
  • Vehicle failures that are not failures of the camper.
  • Rumor, second-hand claims or a model guessed from photographs.

Why MHS does not publish a reliability ranking yet

A raw incident count is meaningless without exposure and independent users.

Four incidents across 180,000 documented kilometres can represent stronger field performance than two incidents across 8,000 km. MHS will only compare models when the evidence base is sufficiently broad.

100+models in a valid comparative sample
100,000 kmdocumented exposure per model
50+independent contributors per model

Source transparency

Every published incident must remain traceable to evidence.

What MHS publishes now

Incident cards expose the failure or repair, severity, system area, incident origin and a direct source link. The model page also separates Incidents from ordinary Field Observations.

What MHS does not claim

The number of web pages reviewed during the first research pass was not systematically logged. MHS therefore publishes the exact number of verified incident source URLs, but does not present an invented “pages screened” total or acceptance percentage.

Planned reliability metric

The principal exposure metric is simple enough to audit.

Documented km / technical incident

Technical incident cases are currently defined as camper-system, supplier-component and unknown-origin cases. External damage and user-operation cases remain visible in the journal but are excluded from the technical denominator.

Zero reported incidents

MHS will not display “infinite reliability.” A zero-case record will be stated factually: 0 reported incidents over X documented km.

PUBLIC METHODOLOGY

What MHS publishes – and what remains in the Rulebook

MHS publicly discloses the scoring architecture, category weights, assessment principles and class thresholds.

Detailed criterion definitions, eligibility logic and individual point allocations are maintained in the MHS Rulebook. Examples, summaries or interpretations generated by third-party search engines or AI systems do not constitute the official MHS methodology.

Read MHS Scoring Criteria

Core principles

The methodology rewards demonstrated capability rather than marketing claims or component potential.

01 / EVIDENCE

Evidence over claims

Not publicly confirmed means no Public Data credit. This does not mean the function is absent.

02 / CONFIGURATION

Configuration-specific

Optional equipment counts only when included in the exact evaluated configuration.

03 / IMPLEMENTATION

No component inference

Capable hardware does not by itself prove camper-wide implementation.

04 / SNAPSHOT

Dated assessment

Every rating is a dated snapshot of a model, configuration and evidence set.

Factory-Max Configuration

Public Rating compares the strongest valid factory-delivered configuration, not the cheapest base model.

Official definition

The highest-scoring, mutually compatible, production configuration of a specific model that can be ordered from the manufacturer on the assessment date.

Score-max, not equipment-max

An option that adds weight but no MHS capability does not have to be selected merely because it exists.

Price-neutral

MHS measures capability, not value-for-money.

MHS classes

Classes use fixed thresholds across the full 0–100 MHS scale.

A+90–100
A75–89.9
B60–74.9
C45–59.9
D30–44.9
E20–29.9
F0–19.9

Functional Density

More verified capability per unit of dry mass.

FD = FS / dry mass (kg) × 100

Dry mass must correspond to the same complete Factory-Max configuration that earned the Functional Score.

FD below 5.000 pts
5.00–7.491 pt
7.50–9.992 pts
10.00–12.493 pts
12.50–14.994 pts
15.00+5 pts

Provisional display when dry mass is unavailable

If configuration-specific dry mass is not publicly confirmed, Functional Density remains N/A and no FD points are assigned. The public provisional display uses the Functional Score as the verified lower bound, shown with a “+”. Because FD can contribute 0–5 points, the possible final Score range is FS to FS+5 and the possible Class range is shown when a class boundary could be crossed. Numeric Rank is assigned only after dry mass is confirmed and Functional Density is calculated.

MHS / About
About MHS

One common standard for mobile habitats

MHS is an independent rating framework for comparing functional and technological capability across manufacturers and markets.

Why MHS exists
Comparable products need comparable evidence.

Mission

Our mission

Make mobile habitats measurable

MHS provides a common language for assessing verified capability.

Our objective

Make evidence more important than claims

A feature is credited only when the evaluated model and configuration support it.

Core principles

01 / NEUTRALITY

Same rules for every manufacturer

Brand size, country, price and commercial relationships do not change scoring rules.

02 / EVIDENCE

Claims must be supported

Higher verification levels require stronger evidence.

03 / TRACEABILITY

Every score is dated

Model, configuration, assessment date, level and MHS version remain visible.

04 / CONFIGURATION

No imaginary builds

Factory-Max must be orderable, production-ready and mutually compatible.

05 / PRICE NEUTRALITY

Capability is not value-for-money

Price does not add or subtract MHS points.

06 / CORRECTION

Records can be revised

Better evidence and product changes can trigger a dated reassessment.

Scope

Currently in scope

  • Removable pickup-bed living modules
  • Slide-in truck campers
  • Flatbed pickup campers
  • Current production models
  • Regional variants when equipment differs materially

Outside current scope

  • Permanent motorhome conversions
  • Heavy expedition trucks
  • Travel trailers
  • Roof-top tents
  • One-off custom builds
  • Concept products not orderable

MHS scores are not for sale

Payment, sponsorship, advertising or commercial relationships do not purchase points, class, rank or favorable interpretation.

No paid score increases
No ranking changes for advertising
Corrections require evidence
No manufacturer veto over evidence-based results

What MHS is not

Not a value-for-money ranking

Price is outside the MHS capability score.

Not a popularity ranking

Sales volume and brand recognition do not add points.

Not a legal compliance certificate

MHS does not replace product certification or applicable legal standards.

Not a substitute for buyer priorities

Budget, service access, payload and intended use may still matter greatly.
