Energy Storage/EV Charging
Grid buffering for Electric Vehicle Quick Charging
Hardware costs for Level III DC Quick Charging stations have been dropping rapidly, but installation costs remain a major barrier obstacle to widespread adoption, often topping $100,000 per station. The key cost driver is often related to establishing 480 volt three phase service and running the high voltage lines to the charging station. One solution to high installation costs is to combine a large lithium-ion battery with standard 220 volt service, allowing the battery discharge up to 50 kW of power when needed and recharge in-between uses. Integrating energy storage with EV charging opens the possibility of smart grid functionality, including peak shifting (storing inexpensive electricity from periods of low demand for use during expensive peak hours) and frequency regulation.
Electric vehicle charging does not need to be limited to areas served by the electrical grid. The combination of solar panels, batteries, and charging stations opens up the possibility of owning and operating EVs anywhere in the world, fueled by 100% carbon-free and pollution-free energy.
Power when you need it the most
Sometimes when the power goes out is exactly when some vehicles are needed the most. First responders and the military are starting to integrate electric vehicles into their fleets. Compact, lightweight and long-lasting batteries integrated into charging installations ensures these critical vehicles will be available no matter what else is happening in the world.
Heat is a battery’s worst enemy, whether from internal or external sources. AllCell’s proprietary thermal management technology can passively absorb environmental heat all day long, keeping cells cool even during discharge and when the battery is exposed to direct sunlight in hot climates. While other batteries quickly lose cycle life in hot conditions (e.g. in lead acid batteries, for every 15 degrees above 77F, battery life is cut in half), AllCell batteries remain cool while minimizing or eliminating expensive air conditioning systems. With smaller or non-existent air conditioning equipment to power, both panel and battery size are minimized, a significant cost saving.
