Energy Storage for EV Charging
Energy storage has become a key enabling technology for front-of-the-meter and behind-the-meter applications. Grid operators, commercial business owners, and homeowners are increasingly looking to storage to help mitigate electricity reliability and cost issues. EVs and their charging systems represent one of the problems that many customers face. EV charging introduces power supply issues in the form of harmonic currents and poor power factors because of non-linear charging equipment. These issues affect the quality of power being supplied to the EV battery, thus reducing its useable life.
Since EV chargers are an electric load that can potentially create large spikes in demand, EV charging station hosts are pressured to do something about their impact on the grid. Navigant Research believes several different solutions will address the peak demand of EVs and the associated charging issues. One solution is to implement EV charging strategies that contain the impact on the grid, thereby guaranteeing the quality of the service. The implementation of a charging strategy is related to the deployment of smart grid technologies like distributed generation, smart monitoring systems, and especially Energy Storage.
We believe that energy storage plays a fundamental role in the smart grid paradigm. It is also fundamental to the integration of the new power systems related to the EV charging stations of the next generation. Energy storage for EV charging (ESEVC) provides the following benefits to the greater EV charging market:
- Reduces demand charges incurred by the customer.
- Decreases charging times and lowers customer range anxiety concerns.
- Creates a better business case for EV owners and charging station operators by providing multiple services to the customer and grid and mitigating customer concerns over mass EV adoption.
- Reduces the carbon footprint of the charging station owner, local utility, and driver.
- Improves grid stability and defers infrastructural upgrades to the utility.
Charging stations have a hidden cost: the need to provide significant power to charge the EV in an increasingly short timeframe. Whenever an EV is connected to a charging station, the building’s electrical infrastructure experiences a high current surge, and consequently, an electrical demand spike.
Energy storage systems (ESSs) are becoming a key solution worldwide in curtailing undesired effects of load on the grid. Navigant Research believes energy storage can benefit EV charging in several key ways:
- Demand charge management: Energy storage can respond automatically to building load spikes and manage charging/discharging patterns based on retail electricity rates, reducing expensive charging rates during peak demand.
- Avoidance of costly upgrades: Faster charging times without increasing cabling and load infrastructure for energy storage for EV charging (ESEVC) owners, customers, and grid operators.
- Grid services: The ESS-enabled charging station may also serve other applications like backup power, demand response (DR), and transmission and distribution investment deferral to open new revenue streams for the charging station owner.
- Greenhouse gas reduction: Discharging/charging stored energy during peak hours reduces load from the grid.
- Smart grid integration: A grid-connected system further pushes the grid toward more vehicle grid integration.
