Charging station control

Peak performance, not peak loads

The grid connection can quickly reach its limits – especially when it comes to larger charging parks or the upcoming expansion work to the electric vehicle charging infrastructure in apartment buildings, supermarkets and commercial enterprises. This is why TESVOLT Energy Manager’s charging station control is a dual benefit.

1. You can avoid expensive grid connection expansion, since the system regulates the power consumption from the regional grid using the TESVOLT battery storage system, avoids load peaks and thus protects against overload.

2. Electricity produced in-house can be used for charging purposes to considerably cut electricity costs.

How you benefit

  • Avoid peak loads
  • Cut electricity costs
  • Avoid expensive grid expansion
  • Smart control over the charging park

How does it work?

The TESVOLT Energy Manager communicates with compatible charging stations and electric vehicles using the vehicle app. Once programmed, the user can make settings specific to the charging station or vehicle.

Charging with excess power: Charging exclusively or primarily from electricity produced in-house that is not needed elsewhere. This can mean charging that only starts when enough in-house electricity has been stored in the battery storage system, i.e. a pre-set charging threshold has been reached. Alternatively, the charging stations are only allocated as much electricity as the facility can produce at any given time.


SoC-based charging: Charging a vehicle up to a pre-set state of charge (SoC). This may be relevant, for example, if the car is only used for short trips.

Prioritising charging stations: Defining which charging stations to supply. For example, customer parking spaces may be prioritised over employee parking spaces because the cars are parked there for a shorter time.

Time-dependent charging of electric vehicles: Setting the time window in which the vehicle fleet is to be charged, e.g. to relieve other consumers or to save costs.

Forecast-based charging of electric cars: Depending on the facility’s expected production output and other criteria, the TESVOLT Energy Manager controls charging of the vehicle fleet in a variable and smart way.

Quick charge: If the required power exceeds the grid connection’s capacity, the battery storage system supplies additional power – as long as the charging station supports this.
