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.

AC loads
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.

冬季管路：为什么温暖的舱体还不够

识别低温部件，区分冬季使用与存放，并为加热失效制定计划。

Overview

显示屏无法描述每段管路的温度

控制面板处的空气温度并不代表每个管路段的温度。贴靠外墙的管道、凹陷处的滤网和排水阀可能以不同速度降温。因此，温暖的舱体并不能证明已实现全面防冻保护。

MHS 说明。绘制水箱、水泵、滤网、加热器、水龙头、室外淋浴器、排水装置和废水储存装置的位置图。对每一项，确定其位置、保护来源，以及加热停止时所需采取的措施。

保温与加热不同

保温会减缓热交换，但不会产生热量。主动加热需要能源和控制。综合采用多种措施可能有所帮助，但必须在声称的运行条件下验证其能力。

冬季套件标签不是充分的描述。应明确哪些部件受到保护，以及该配置需要多少电力。缺少细节并不等于证明其失效，但也不能据此支持在安全冰冻天气中的承诺。

冬季运行与空置存放

有人居住的冬季使用可能会在预期的加热条件下保留水。无人居住的存放通常需要不同的准备程序。停止加热后，不要仅仅因为旅途中运行正常，就让管路保持充水状态。

MHS 说明。加热中断所造成的后果取决于天气和部件位置。本指南不提供适用于所有情况的安全小时数。请遵循露营舱说明和实际情况。

水箱排空不代表管路排空

水可能残留在水泵、滤网、阀门、淋浴软管和低位管段中。排空主容器只是准备工作的一部分。水龙头位置和其他步骤取决于管路系统。

附有单独冬季化部分的水泵说明

不要任意施加压缩空气压力来加快排水。如果允许吹出排水，条件必须适合每个受影响的部件。否则，试图采取防冻措施可能会损坏设备。

加热器排水阀的保护范围

某些套件包含温度响应式排水阀。请在实际产品上确认其是否存在、适用条件和保护范围。一个加热器阀门不会自动排空水泵、室外淋浴器和灰水箱。

组合式加热器设备及保护要求示例

不要临时设法使安全排水装置保持关闭。意外排水需要了解相关条件和说明。为保留水而解除保护可能造成损坏。

不合适的替代品

汽车冷却液和玻璃清洗液并不是通用的饮用水管路冬季化产品。只有在已安装系统允许采用该方法时，才可使用经批准的产品和程序。

明火解冻、临时使用电加热器以及绕过温度限制都不安全。如果怀疑发生冻结，不要让水泵强行对着堵塞的管路运行。安全解冻和完整性检查需要适用的说明。

为断电制定计划

MHS 说明。决定如何检测加热丧失，以及如何安全排水。传感器应安装在真正容易受影响的位置才有用，而不应只安装在温暖设备旁边。互联网警报不应是唯一的警告方式。

保留易于理解的操作程序和排水位置指南。在车上装有普通行李且处于黑暗中时，也应能够使用该指南。冬季准备不仅包括硬件，也包括易于执行的操作。

要点

检查最冷的部件，而不只是舱体温度。区分受保护的运行状态与存放准备，并了解加热停止时应采取的措施。

Where it fits

  • 规划旅行期间的用水和维护。
  • 检查已完成的系统并为存放做准备。

What to verify

  • 保持饮用水、传热流体和废物彼此区分。
  • 检查是否能够接触需要维护和容易受影响的部件。
  • 遵循实际系统关于压力、清洁和排水的说明。

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
Toilet
Air conditioning
Pop-up roof

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.

MHS Methodology

How mobile habitats are rated

MHS evaluates factory-delivered functional and technological capability using a common evidence-based framework.

Maximum MHS Score
100
Functional Score contributes up to 95 points and Functional Density contributes up to 5 additional points.

MHS = Functional Score + Functional Density points. The total maximum is 100 points.

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.
