Case Study/Residential EV Charging/Sweden

One platform. Every charger.
Every tenant.

Gladsheim Fastigheter
“After a year of searching, I found software that gives me control of all my EV boxes, brand-independent. For a reasonable cost, Powerfill gives me a flexible solution with space to grow.”
Karl-Gunnar Eriksson · CTO, Gladsheim Fastigheter

Gladsheim Fastigheter needed to manage EV charging stations alongside the doors, apartments, and laundry rooms they already administer through Amido Access. Powerfill built a turnkey integration that synchronizes access data from Amido Access into Powerfill automatically, now available to any Amido customer.

Access management,
extended to charging.

Gladsheim manages rental housing across mid-sized Swedish towns. Doors, apartments, laundry rooms, and other resources are already organized in Amido Access, with tenant access granted through RFID keys. EV charging is the next resource layer, and it needs to fit into the same structure.

Gladsheim Fastigheter AB

3,000+ apartments across 15 Swedish towns.

Ares Management-backed landlord with published sustainability commitments. As the portfolio expands, EV charging joins doors, apartments, and laundry facilities on the list of resources that require managed tenant access through a single administrative system.

The Challenge

Two systems,
the same data.

Without integration, running EV charging through Powerfill meant maintaining the same data in two places. Stations, RFID cards, and access rules already existed in Amido Access. Replicating them in Powerfill and keeping both systems in sync required manual work on every change.

01

Multi-brand charging

Charging stations from different manufacturers need to be managed through a single CSMS, not a separate app per vendor.

02

One key, everywhere

Residents already hold RFID keys through Amido Access for doors, laundry rooms, and shared resources. The same keys should work at the charger.

03

Unified administration

Access control and energy consumption reporting belong alongside the other facility workflows, not in a parallel system.

04

No manual duplication

Stations, cards, and permissions already exist in Amido Access. Rekeying them into Powerfill by hand on every change does not scale.

The Solution

Four layers,
one source of truth.

Amido Access remains the system of record for resources and access. Powerfill mirrors it automatically for charging stations and OCPP tags. Open protocols end to end, with no duplicate data entry.

Reference architecture / Gladsheim deployment
Layer 01Tenant Identity
The tenant's existing RFID key, already provisioned for doors, laundry, and intercoms. No second credential to issue.
MIFARE / DESFIRE
Layer 02Amido Access
System of record for apartments, contracts, grants, and cards. All tenant data lives here; Amido Access stays canonical.
REST API / UUID
Layer 03Powerfill
The charging management system. Reads Amido Access on a schedule, provisions stations and OCPP tags, applies permissions automatically.
OCPP 1.6J / REST
Layer 04Hardware
Any OCPP-compliant charging station, regardless of manufacturer. Station replacement or addition is a configuration change, not a migration.
OCPP / BRAND-AGNOSTIC
How it works

Amido Access stays the source of truth.
Powerfill stays in sync.

Every Amido Access folder, access group, card, and grant maps to a corresponding entity in Powerfill. The sync runs automatically. Administrators continue working in Amido Access; Powerfill updates on the next run.

01Tree mirror

Every Amido Access folder becomes a Powerfill site node under a synthetic root. New folders, moved stations, renamed nodes are all picked up automatically.

AmidoAccessRoot // synthetic root ├── Region A │ ├── Building 1 │ │ └── station │ └── Building 2 │ └── station ├── Region B │ ├── Building 3 // 1 station, 1 card │ └── Building 4 // 1 station, 1 card └── Region C └── ...

02Deterministic mapping

A small set of rules, applied on every sync run. No fuzzy matching, no guesswork.

  • Amido Access folder Powerfill site node, with the tree shape preserved
  • Amido Access charging access group Powerfill station
  • Amido Access card with a recognized RFID code Powerfill OCPP tag
  • Amido Access grant Powerfill permission on the matching node
  • Amido Access IDs preserved on every synced object for full traceability

03Time-aware state

Card validity and access grants from Amido Access determine whether an OCPP tag is active or blocked in Powerfill. Future starts, expirations, and revocations are reflected automatically on the next sync.

  • Archiving a card in Amido Access blocks it in Powerfill
  • Future-dated cards are pre-provisioned and activate when their start date arrives
  • Cards with an end date block automatically at expiry
  • Grants with time windows open and close permissions on schedule

04Billing-ready reporting

Monthly energy consumption reports built on the concepts Amido Access already defines, apartments and card owners, with no separate billing data model to maintain.

  • Consumption attributed to the card owner defined in Amido Access
  • Reports use identifiers already in place across the customer's access management
  • No manual mapping between charging sessions and tenant billing
Integration principles

Predictable behavior,
by design.

Four principles define how the sync treats existing data on both sides. They make the integration safe to run on a live Powerfill account from day one.

Principle 01

Charging history preserved

Archiving a station in Amido Access blocks it in Powerfill while preserving its historical data. Reactivation is possible at any time.

Principle 02

Powerfill-native assets untouched

Assets created directly in Powerfill, such as test chargers or ad-hoc sites, are not modified by the sync.

Principle 03

Full reconciliation each run

Each sync evaluates the full Amido Access snapshot end to end. No drift, no partial states.

Principle 04

One place to make changes

Administrators make changes in Amido Access. Powerfill reflects those changes on the next run.

Outcomes

Three parties,
three sets of benefits.

Each party benefits directly from the same integration. No compromises, no dependencies.

Why now

The 2026 rules are in force.
Every Swedish landlord is in scope.

Three regulatory shifts moved residential EV charging from a sustainability choice to a compliance requirement. The Klimatklivet reform, the right to install, and the EPBD are all in force in Sweden.

1 FEB 2026 / IN FORCE

Klimatklivet reformed

"Ladda bilen" sub-programme
Now under GBER Art. 36a

Klimatklivet is Sweden's flagship climate investment subsidy, administered by Naturvårdsverket. Its "Ladda bilen" sub-programme covers up to 50% of eligible cost, capped at 15,000 SEK per charging point, for non-public charging at BRFs, fastighetsbolag, and workplaces.

Since 1 February 2026, "Ladda bilen" runs under the EU's General Block Exemption Regulation, Article 36a. The de minimis cap that previously limited grants per corporate group is gone. Applications are filed ex-ante, before the project starts, and portfolio operators can submit consolidated applications across multiple buildings.

Implication Portfolio operators plan rollouts upfront and apply once across many buildings, with metering and reporting in place from day one.
SPRING 2026 / IN FORCE

Right to install

Swedish rules per Ds 2025:13
Justitiedepartementet

Under the Swedish right-to-install rules in Ds 2025:13, both tenants and BRF members can request installation of a charging point at their parking space, at their own cost.

The landlord or BRF board can refuse only on "sakliga skal", legitimate technical or economic grounds. A blanket "we do not offer charging" answer no longer holds.

Implication A platform that handles one-charger installations as cleanly as portfolio rollouts is an operational requirement now that individual tenant requests carry legal weight.
1 JUL 2026 / IN FORCE

EPBD in Swedish law

EU Directive 2024/1275
Transposed via PBL and the energy declarations act

The recast Energy Performance of Buildings Directive (EU 2024/1275) set an EU-wide transposition deadline of 29 May 2026. Sweden transposed it through PBL and the energy declarations act, in force since 1 July 2026.

The directive's charging infrastructure requirements for buildings now apply in Swedish law.

Implication Building projects now include EV charging infrastructure by regulation. Each project needs a charging backend ready to operate what gets installed.
