Battery Buffered EV Charging
Battery Buffered Electric Vehicle (EV) Charging is the use of a battery storage system to reduce the impact of EV chargers on your overall power demand.
This allows you to implement multiple slow chargers or even high power, rapid chargers without the spikes in demand that they would otherwise cause. In some cases, it may be essential in order to add the charging capability to a site’s load profile and connect them to the National Grid.
How battery buffered EV charging can help you
Battery buffered EV charging is an application of Powerstar’s battery energy storage solution, which enables you to store electricity on your site. The battery can be charged more slowly than the electric vehicles, meaning that the additional demand to your site’s authorised capacity is dramatically reduced. If the site is already operating near its maximum capacity, it may be impossible to implement rapid charging without paying your Distribution Network Operator (DNO) to increase capacity. A battery buffer can eliminate the need for upgrades.
If your site has, or will have in the future, renewable generation, such as solar PV, then the battery system can be used to store that electricity for directly charging electric vehicles. On-site renewables are unlikely to generate enough power to charge a vehicle, but by storing the energy over a longer period of time in the battery system you can ensure that the vehicle is charged with 100% clean electricity.
How does battery buffered EV charging work?
Any type of EV charger can be integrated to a bespoke battery storage solution, including the charger head (e.g. CHAdeMO/type 1/type2) and the charging power (e.g. 50/100/150kW). The battery system stores electricity as a DC supply, rather than the normal AC supply of your site. DC charging can be much higher speed and thus a battery connected system is ideal for rapid chargers (more than 11kW).
The chargers are directly connected to the battery so that the vehicles charge rapidly from the electricity stored in the battery. The battery then recharges at a slower rate from the National Grid supply, or from on-site generation.
The system can be integrated with any form of on-site generation, such as solar PV.
How to implement battery buffered EV charging
Powerstar can customise and install its battery energy storage systems to suit your electric vehicle charging requirements. The artificial intelligence driven microgrid control can automatically optimise the charging patterns to ensure that the cheapest and cleanest electricity is used at all times.
Which sectors benefit most from battery buffered EV charging?
In order to facilitate the move forward to more electric vehicles on the road, every sector would benefit from battery buffered EV charging as the demand for electric vehicle charging increases.
Sites that need to manage fleet vehicles will have the greatest need. If vehicles need to be charged in a short period of time to keep the vehicles and/or drivers utilised as much as possible then rapid charging will be essential. Distribution centres, service fleets, transport hubs and delivery operations are perfect examples of this sort of operation.
