A load balancer, also known as a load distributor, is a device or software component used to evenly distribute traffic, tasks, or load across multiple resources or targets. In the context of electric charging stations, a load balancer refers to a system responsible for distributing the available electric power between the connected charging points or vehicles.

The load balancer monitors and manages the energy consumption of the charging stations and distributes the power in a smart and efficient manner. The aim is to prevent overloading of the power grid and ensure that the total power consumption remains within capacity limits.

A load balancer can perform various tasks such as measuring the energy consumption of each charging point, monitoring the available capacity of the power grid, determining the optimal distribution of power, and adjusting the charging speed or power per charging point if necessary.

By using a load balancer, charging points can be used simultaneously without causing overload. It also helps to optimize charging time and ensure that all connected vehicles are charged efficiently.

In general, a load balancer is a crucial component in systems involving multiple resources or targets, where a balanced distribution of the load is essential to ensure performance, reliability, and efficiency.
