Introduction to mobile lithium ion battery energy storage system



Share it:

The emergency power supply system of lithium-ion battery mobile energy storage power station selects lithium-ion batteries with excellent safety, long life and high energy density as the energy storage power source. At the same time, it combines the design ideas of online UPS to realize the integration of city power and energy storage power. Seamless switching to meet emergency power supply and uninterrupted power supply for important loads, and the power supply is more flexible and reliable.

The mobile energy storage system is an energy storage device that integrates an energy storage battery system, a battery management system, an energy management system and a transportation platform. It has the characteristics of flexibility, fast response, and convenient maintenance. It is widely used in power supply, emergency communications, important activities, rescue and disaster relief, military command, field exploration and other fields.

In some application areas, such as ensuring short-term power supply for key facilities and adjusting load curves in seasonal areas, mobile power storage systems must be adopted. Mobile lithium-ion battery energy storage systems have relatively large requirements in different multi-dimensional scenarios. One is the flexible deployment of energy storage power stations, seasonal load power supply, and electric vehicle road rescue, which are aimed at the diversification of application scenarios and the complexity of the environment. The performance puts forward a higher requirement for the comprehensive performance of the mobile energy storage system.

1. Key technical quality and safety

Quality and safety must first mention the lithium-ion battery, because the battery currently has multiple battery systems, multiple types and multiple manufacturers, and different manufacturers have different models. There are several overall safety and quality. The safety protection thermal field is uniform and the heat insulation resistance Combustion, fire fighting and extinguishing, these two key points are reflected in our entire electrical appliances, structure, and heat dissipation.

2. Battery selection

Currently, there are more lithium iron phosphate batteries in use. Because different manufacturers’ products are also very different, there are still certain differences in product performance, battery abuse, and even energy storage technology standards now have national standards. Some standards are not strictly enforced. As a result, the performance difference of lithium-ion batteries is extremely large, and even the consistency is poor, so the selection of high-quality batteries.

3. Battery Management

For the management of the battery installation cycle, there is a problem that the information collection is now inaccurate. In addition, regarding the status evaluation, SOC, SOH, the voltage collection, temperature collection, analog quantity collection, and the estimated impact on the operation of your entire system, it is said to achieve high precision The long-term stable lithium-ion battery management system is also a key to the safe application of mobile energy storage.

4. Uniform thermal field, thermal design thermal simulation

We evenly cover the thermal field in the entire system, inside a car, and the thermal field simulation requires a full-scale platform to do this. Therefore, the entire thermal field simulation battery of the entire battery also understands that it has electrochemical performance. The management of the entire thermal system with particularly high temperature requirements is also the focus of the safe and efficient operation of energy storage.

5. Security protection

Now with this safety protection, if the lithium-ion battery is thermally out of control, and the diaphragm is added to isolate the temperature and heat, there are now two problems. The first is that there is no isolation between the batteries. This problem will also exist if excessive protection is added. One is my thermal insulation design, and the other is that I use different over-protection, which brings about heat accumulation. So now, it is a strategy of solid and reliable heat dissipation and comprehensive protection. This is also a safe energy storage mobile. Strategic guarantee.

6. Fire fighting

Although lithium iron phosphate batteries are safe to use now, there is also a fire hazard for safety. At present, for safety research, there are two aspects, one is fire fighting and re-ignition, and the last one is necessary for mobile energy storage safety. Measures.
