The popularization of electric vehicles has an impact on the power grid. Especially in the evenings, as commuters return from work, many EV users charging at the same time leads to a surge in electricity demand.

If the sudden increase in electricity demand cannot be met, problems such as unstable power supply, voltage fluctuations, and even local power outages may occur.

To realize the full environmental benefits of electrified transportation and maintain grid stability, dynamic load balance management plays a crucial role. Its advantages cover areas like grid stability, charging safety, energy distribution, and more.

How Does Dynamic Load Balance Work?

Dynamic load balance functions by actively tracking power usage throughout the distribution network. Sensors relay current loads to control systems, which then calibrate individual charger outputs to maintain an optimum overall load. 

For example, when the EV charger works simultaneously with other appliances, the DLB box can set the maximum current value of the main line. The charger will read the current value and adjust the charging current (6A-32A) based on the idle load quota, thus maintaining the dynamic balance of the household current and ensuring the safety of the electric vehicle.[1]

Why Dynamic Load Balance is Important?

Dynamic load balance plays a critical role in maximizing the benefits of electrified transportation through its many advantages. These include (but are not limited to):

Maintain Battery Life and Performance

By preventing overtaxed charging sessions, dynamic load balance protects battery health and performance over the long term. Precisely regulated currents avoid overcharging, which can severely degrade cell lifespans over just a few years. 

The balanced load further ensures consistently high battery performance to empower drivers’ daily routines.

Optimize Energy Use

By adjusting power demand and supply in real-time, dynamic load balancing can ensure efficient utilization of electricity when needed. This reduces energy waste, especially when demand is lower than supply. Resources can be saved by reducing electricity consumption.

Improve Charging Efficiency

Dynamic load management EV charging also streamlines the driver experience. Intelligent load coordination means charging stations reach capacity more smoothly without long wait times during peak hours. Dynamic load balancing will automatically adjust the charging speed and power of electric vehicles based on the energy usage in your location.

Improve User Experience

Together, charging optimization via dynamic load balance delivers improvements to the user experience. Dynamic load balance strengthens grid resiliency so that even more drivers can charge seamlessly without facing inconveniences like capacity shortfalls or outages. This reliability boosts real-world EV convenience.

The Potential of EV Charger Integrated Energy Storage Systems

Integrating energy storage systems into EV chargers empowers dynamic load balance even further. Firstly, energy storage systems can store energy during low grid loads and then use this energy to charge electric vehicles during peak hours. This can significantly balance supply and demand, avoiding household overload.

Secondly, combining charging stations with energy storage systems reduces dependence on the power grid. Even when the power grid is tight, charging stations can use the energy storage system’s power to maintain charging power. This reduces the waiting time for charging and makes electric vehicles more convenient.

The technology represents a major step toward seamless EV integration and a more sustainable energy future. Seasoned EV solution providers offer a variety of high-quality integrated energy storage products designed to maximize the benefits of vehicle-grid integration.

Dynamic Load Balancing Technology of EVB Charger

EVB Charger understands the user’s demand for EV charger load management, so our AC EV chargers are equipped with DLB technology. It can actively monitor the charging current in real-time without the need for a separate meter to monitor power load management. This not only protects the electric vehicle charger but also effectively prevents overload tripping.

In addition, to promote clean energy, our charging stations also have a photovoltaic DLB mode, which sets up the use of electricity from solar panels and limits utility electricity consumption. This not only reduces the pressure on the power grid but also saves your electricity bills.
