A load balancer, also known as a load distributor, is a device or a software component used to distribute traffic, tasks, or load evenly across multiple resources or targets. In the case of electric charging stations, a load balancer refers to a system responsible for distributing the available electrical power among 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 goal is to prevent overloading 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 power distribution, 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 an overload. It also helps to optimize the 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 load distribution is essential to ensure performance, reliability, and efficiency.
