energy storage batteries System
EnergyStorageSystem (ESS) is a system that can store electrical energy and supply power, with functions such as smooth transition, peak-load shifting, frequency and voltage regulation, etc. It can smooth the output of solar and wind power generation and reduce the impact of randomness, intermittency, and volatility on the grid, domestic users, and industrial and commercial users. The excess electric energy is stored in the energy storage battery by charging during the valley price periods. Discharging during peak price periods can reduce users’ electricity bills. When the power grid is powered off, it can operate independently to ensure an uninterrupted power supply to users and the operation of the microgrid. When the grid needs or at peak hour times, the energy in the battery is fed into the grid through the energy storage inverter, and the price difference between peak and valley electricity is used to create greater economic benefits.
The energy storage system is mainly composed of photovoltaic modules, on-grid, and off-grid control inverters, battery packs, distribution boxes, loads, etc. Because battery energy storage has the advantages of relatively mature technology, large capacity, safety and reliability, low noise, strong environmental adaptability, and easy installation, batteries are often used in energy storage systems to store electrical energy. At present, the energy storage system is mainly composed of the energy storage unit and monitoring and dispatching management unit. The energy storage unit includes Battery Accumulator (BA), Battery Management System (BMS), Power Conversion System (PCS), etc.; the monitoring and dispatching management unit includes Microgrid Central Controller (MGCC), Energy Management System (EMS), etc.
Application scenarios of energy storage: It can be divided into the front of the meter including the power generation side, the Shipping Container Solar System on the grid side, and behind the meter including High Voltage Energy Storage, Commercial Battery Storage, and Home Battery Storage. Besides, energy storage is also applied to 5G base stations, portable energy storage, yacht, RVs, and other fields.
Benefits of Lithium batteries
Lithium Iron Phosphate Battery refers to the lithium-ion battery with LiFePo4 as the positive electrode material. The anode materials of lithium-ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, and so on, among which lithium cobaltate is the anode material used in the vast majority of lithium-ion batteries. In terms of material principle, lithium phosphate also contains an embedding and de-embedding process, the same as lithium cobalt and lithium manganese.
Lithium iron phosphate has high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, large current charge-discharge, electrochemical stability, and safety in use (no combustion or explosion caused by improper operation of overcharge, over-discharge and short circuit), wide operating temperature range, non-toxic or less toxic, no pollution to the environment. A Lithium phosphate battery with LiFePo4 as the anode is good for these performance requirements. Especially in terms of large discharge rate (5-10C discharge), stable discharge voltage, safety (no combustion, no explosion), life (cycle times), and no pollution to the environment, lithium Ferro phosphate battery is currently the best high-current output lithium-ion battery.
Lithium Iron Phosphate Battery is generally considered to be free of any heavy metals and rare metals (nickel-metal hydride battery requires rare metals), non-toxic (SGS certified), non-polluting, in line with European RoHS regulations, and is absolutely the green environmental protection battery.
Home Battery Storage
Home energy storage products are concentrated in 5-30kwh according to different demands and have high requirements on battery safety and service life. Generally, they require more than 10 years of warranty, and the cycle times are up to 6000 times or more. Lifepo4 battery for solar energy storage is more suitable for house battery storage due to its features of low cost, high safety, and long cycle life.
The home battery storage without solar consists of a home network, a home server, and a mobile phone terminal, which is simple, effective, and has good scalability. Based on the energy efficiency management of battery power storage systems, the target consumption of the lowest total electricity cost is achieved by establishing home power storage and making use of home power storage solutions in combination with the time-of-use electricity price. The suitable home energy storage battery can be selected based on the actual situation to optimize the utilization of household load, improve the operation economy and maximize the economic benefit.Meanwhile, peak shaving battery can also play a role. Finally, a simulation test is carried out on the electrical equipment of the home battery storage system. The energy efficiency management algorithm can effectively save the total cost of household electricity cost, proving the effectiveness and feasibility of home energy storage systems.
RV Battery & Camping Battery
1. More available capacity
Unlike a lead-acid battery, which rarely discharges more than 50%, a lithium RV battery can regularly discharge 80% or more of its rated capacity. For example, with a 100Ah battery ⸺ with a lead-acid battery, you can only get 30~50Ah, but with a lithium RV battery, you can get 80Ah or more. It’s about twice as high as an equivalent rated lithium battery pack, just like an AGM battery
2. Long cycle life
A lithium-ion RV battery costs about three times as much as an AGM battery, but the longer life makes it worthwhile. A lithium-ion RV battery can be recharged 5,000 times and retain 80% of its original capacity, while the best deep-cycle AGM battery typically only does 500-1,000 cycles.
3. High current output
The best lithium RV battery can be charged at high current rates without loss of Ah capacity, while the lead-acid batty can be reduced to a 40% Ah rating at high discharge rates.
Marine Battery & Trolling Motor Battery
There are a large number of boat batteries in electric ships, which requires a high discharge rate, circularity, and cost. In terms of the selection of battery type, compared with lead-acid batteries, lithium iron phosphate batteries have obvious advantages in safety, energy density, cycle performance, etc. In the future, the trend of lithium electrification of ships will mainly focus on the markets of ferries, sightseeing boats, inland cargo ships, port tugboats, etc. in coastal cities. Some large and medium-sized ships also use lithium batteries to replace lead-acid batteries, thus promoting the acceleration of the marine use of lithium batteries.
Marine batteries are specially designed for use on board, whose steel plate is heavier and the construction is strong enough to withstand the vibrations and shocks that can occur in any powered boat. For this reason, marine batteries are generally more expensive than car batteries. Common rental battery voltages are 12-volt lithium marine battery, 12v deep cycle marine battery, 24v lithium marine battery, 36v lithium marine battery, etc.
Lithium golf cart batteries
Lithium-ion golf cart batteries, the perfect replacement for lead-acid batteries, have started to be used in quantities for golf carts, sightseeing carts, stackers, forklifts and more. With some features like a long cruising range, free maintenance and long service life, they are currently the best golf cart batteries. In terms of battery types, lead-acid batteries occupy a dominant market share due to their low-cost advantage over other battery technologies. The recyclability of lead-acid batteries increases the availability of raw materials, which is another factor driving their use. Besides, the performance of lead-acid batteries has been improving due to innovative technologies such as the addition of carbon, which have helped improve their efficiency and overcome technical shortcomings related to slow charging, short life and maintenance requirements, but they are still not as good as lithium golf batteries.
Lithium golf cart batteries use deep cycle batteries for power propulsion because these batteries have thicker plates that allow deep discharge and operation at maximum capacity, thus providing a stable current over a longer period of time.
