company news about Junext Assistant, teaching you how to choose parking lithium batteries

The first key point when choosing a parking lithium battery is that consumers must understand the brand strength of the manufacturer. Such as production scale, technological strength, and brand values. Is there a long-term plan to build a brand. If manufacturers do not create excellent products, constantly polish, update and iterate their products, and simply piece together a product, then this type of "small workshop" is basically not worth considering, and card enthusiasts should be cautious and avoid pitfalls.

With the rapid development of new energy vehicles starting in 2022, vehicle grade battery cells are the best choice for parking lithium batteries. Taking leading domestic battery manufacturers CATL and BYD as examples, their battery cell quality for automobiles is beyond doubt. As a parking lithium battery used in energy storage scenarios, lithium iron phosphate is more suitable for safety and stability in battery cell materials. However, many lithium battery manufacturers on the market use graded battery cells and falsely claim to be brand new A-grade, using low-priced marketing tactics to pass off inferior products as good ones. So when it comes to choosing lithium batteries, we should keep our eyes open and not be tempted by low-priced lithium batteries.

The BMS battery management system plays a crucial role in lithium batteries, ensuring the safe, reliable, and efficient operation of the battery pack through comprehensive monitoring and management. It has multiple functions such as charging, discharging, and short-circuit protection. Excellent BMS functions also improve battery safety and extend service life, such as charging current limiting function. When the battery is first charged, the voltage is generally low. If BMS does not limit it, the charging current may be large, causing the battery temperature to rise and potentially causing accidents such as fire. We can feel it by touching the battery or generator while charging, and if it is noticeably hot, there is no charging current limiting function.

The shell of the lithium battery for parking air conditioning serves as a physical protection, while also involving heat dissipation on the basis of waterproofing, moisture resistance, and shock resistance, which is easily overlooked. During the operation of a truck, it will experience various harsh environments. If the battery is not fully protected, it will damage the internal BMS components and battery cells, causing irreversible failures to the parking lithium battery.

Finally, regarding the selection of battery capacity. Lithium batteries are different from lead-acid batteries, and their cycle times have made a qualitative breakthrough compared to lead-acid batteries, reaching up to 3500 cycles. It is 10 times that of lead-acid batteries, fully meeting the service life of 8-10 years. Of course, it is recommended to choose the appropriate lithium battery according to one's own needs. Taking the JN300 model Junneng lithium battery as an example, with a battery capacity of 5.37KWh, it can continuously use the parking air conditioning for more than 10 hours during the day, making it suitable for long-distance transportation drivers. The JN210 model's 3.84KWh is suitable for drivers engaged in short distance transportation. Choose the appropriate capacity for the parking lithium battery based on your own working conditions.

Our Junneng lithium battery products are also equipped with a hot aerosol automatic fire extinguishing device. Through temperature sensing start-up, once the product reaches a high temperature, a large amount of sub nanometer solid particles and inert gas mixture will be quickly generated, covering every corner of the parking lithium battery in a high solubility smoke like three-dimensional fully submerged manner, suppressing the spread of fire and achieving comprehensive control. The BMS thermal management system and hot aerosol provide dual protection for the product, which is currently one of the few lithium parking batteries on the market that uses dual protection to ensure customer safety.
