China's battery testing standards are too many and there is actually a lack of organic coordination

At present, there are 76 electric vehicle standards in China, and from the perspective of testing, including from the perspective of vehicle development, the most concerned is the battery
.
The problem of batteries involves both safety and cost
.
In addition to national standards, it is also necessary to compare
it from three aspects: electrical performance, cycle life and safety.

Now the safety detection system required by the battery is characterized from five aspects, a specific safety test has many items, each test project in the middle of the process, including whether it can be normal boot, start, whether there is an alarm and so on
。 According to the appearance of the detection function is divided into five categories, from no impact at all, to only the software has some impact, but some failures are not recorded, it needs to be restarted, and finally to the entire equipment, the entire battery system, in the entire specific cycle, from high temperature to low temperature, in this process, can not be used and turned on normally, but out of this test environment, to a normal use environment, its hardware is not damaged, and can be turned on
.

There are many testing requirements in the current standard, but in fact there is a lack of organic coordination
.
From an evaluation point of view, the ideal power battery requires high energy density, low cost, long life, maintenance-free, and does not consume strategic resources, etc.
, if these can be done, it is difficult for fuel vehicles to survive
.
Of course, lithium batteries may still be in the basic stage, and some new batteries are either production process problems or safety problems, so these problems may be difficult to promote
on a large scale in recent years.

Domestic battery large-scale production and storage has three aspects of problems, product evaluation, compromise products may have some different degrees of problems, may be very high process accuracy and material requirements of the product, but also through the high-quality elimination rate to screen, it is difficult to achieve large-scale production
.
Production processes, raw materials and other issues must be considered
.
From the perspective of batteries, it is necessary to do some modular batteries, and lead-acid batteries are good because they can be used
when connected.
Maybe the car field is difficult to push, maybe smaller models can push some modular batteries
