Conceptual demonstration
Overnight EV charging at a van depot
How a depot could charge an electric van fleet overnight within its grid connection, using load management and charging schedules linked to vehicle data.
Conceptual demonstration
This is a conceptual demonstration: a worked example of how LIOMO would approach this kind of system. It is not a client project, and it describes no real customer, site or result.
Challenge
The scenario
Imagine a company replacing part of its diesel vans with electric ones. All vans return to one depot in the evening and must be ready in the morning, but the depot grid connection was sized for a warehouse, not for charging many vehicles at once.
Approach
How LIOMO would approach it
01
Connect
Assess the grid connection and existing loads, then select chargers that support open protocols such as OCPP and fit a meter at the connection point.
02
Collect
Bring charger sessions, meter readings and vehicle return times into one platform.
03
Understand
Compare the energy each van needs with the time and capacity available overnight.
04
Act
Share available capacity dynamically between chargers so the connection limit is respected and every van is charged by departure.
Architecture
System components
- 01
Chargers
AC chargers for overnight charging, managed over an open protocol.
- 02
Site meter
Measures total site load so charging can use only the remaining capacity.
- 03
Charge management
Load balancing and schedules based on departure times.
- 04
Fleet data
Return times and distances from fleet tracking inform charging priority.
What it shows
What it illustrates
Work within the grid you have
Load management before expensive connection upgrades.
Avoid lock-in
Open protocols keep the choice of chargers and software separate.
Energy and fleet as one system
Charging decisions informed by how the vehicles are actually used.
