Method and device for charging electric energy stores

A method for charging electric energy stores comprising the following steps:

• connecting at least two electric energy stores to be charged to in each case one charger,
• charging the at least two electric energy stores with in each case one charging power assigned to the respective charger, and
• performing closed-loop control with respect to the charging powers, wherein
• the instantaneous charging power of each charger is determined, the instantaneous charging powers are added to give an instantaneous total charging power,
• the instantaneous total charging power is compared with a predefined upper charging power limit, and
• at least one of the charging powers assigned to the respective chargers is reduced when the instantaneous total charging power is greater than the predefined upper charging power limit.

A device for charging electric energy stores, having

• at least two chargers for charging in each case one electric energy store with in each case one charging power assigned to the respective charger and
• a closed-loop control unit,
• wherein the closed-loop control unit is configured to perform closed-loop control with respect to the charging powers of the respective chargers used for charging during charging of at least two electric energy stores, which are each connected to one of the at least two chargers, wherein:
• the instantaneous charging power of each of the chargers used for charging the at least two electric energy stores is determined,
• the instantaneous charging powers are added to give a total charging power, and
• the instantaneous total charging power is compared with a predefined upper charging power limit, and
• at least one of the charging powers assigned to the respective chargers is reduced when the instantaneous total charging power is greater than the predefined upper charging power limit.
