Storage for e-mobility and charging infrastructure

In practice, charging infrastructure usually fails not at the charging station but at the grid connection. Several charging points or DC chargers create very high short-term power demand.

The starting problem

EV fleets, employee charging, customer charging or DC charging stations can overwhelm the grid connection. Grid upgrades are often expensive or slow. And PV power is not always available when vehicles are charging.

How a storage system can help

A storage system can buffer charging power, make PV power usable at a later time, reduce load peaks and relieve the grid connection. Combined with charging management, the result is a controllable system.

Key planning factors

• number of charging points
• AC or DC
• simultaneity
• charging times
• available grid capacity
• PV surpluses
• the business’s load profile
• charging management and Modbus

When caution is advised

Caution is advised when simultaneity and charging times are unknown or no charging management is planned: without controlled charging points, a storage system is quickly undersized or simply ineffective.
