Planning is safe. Lithium battery manufacturers believe that the first PACK planning concept is considered to consider security factors, and the analysis of the unsafe factors from the way to prevent the safety.
Analysis from the current security incident, 90%is caused by the charging and discharge process. The first thing that occurs in the charging process is that the short -circuit 0.1 ‰ caused by the battery thermal heating is less controlled by the storage process. Caused by oscillation, impact, or soaking in the process, is basically caused by short circuit.
From the perspective of PACK, our needs are:
A, the battery connecting fixed method, anti -impact oscillating;
b, choose a suitable multiplier battery cell to avoid the Mavericks from pulling a large car and increase the heat capacity of the core;
c, the safe -planning battery bracket safety spacing provides a core heat dissipation path (how to send out the heat that occurs during the charge) or the whole idea of other heat dissipation methods to plan for planning.
In the analysis of the incident, there are few production factories in production or storage. The main thing is that it is still good for safety defense. The problem that simply presented in the process of the customer's application is:
A, improper use of the charger, charge a low voltage lithium battery with a large voltage charger. The use of conceptual needs can be changed throughout.
b, caused by soaking in water in the process, now lithium batteries are now available in waterproof IP64 (grade water), and better IP65. If you do not pay attention to keeping, soak water for a long time will still cause short water circuit. Some people will have some people. It is enough to say why I do not achieve the IP67 level. Sometimes the opportunity will talk about some plans from the perspectives of operation and balance.
C. With the coming of Internet+, the battery will also enter the era of intelligence and start to carry out in the direction of interconnection, intelligence, and interaction. It can use mobile phone apps or WeChat mini -programs for human -computer interaction to change the usage habits of customers.
