Recently,Rumors about the new national standard have a wave of high tideAccording to the related media reports,Miit will today held a press conference,About electric bicycle standard revision,The new national standard revision does not only have the official leadership to confirm,And leaders of the industry, and also issued a public opinion support.

It is certainly safe to test the 18650 lithium battery with professional capacity tester, internal resistance tester and aging equipment, but this is a professional situation If you want to test the capacity of 18650 lithium battery, you can use comparison method.

As the name implies, the battery is stored first and then supplied to the external machine of the battery The battery is the most widely used battery in the world because of its low price and safe use of electricity.

Different types of batteries have different internal resistances The same type of battery has different internal resistance due to inconsistent internal chemical characteristics.

In a lithium-ion battery (LIB), lithium ions move back and forth between electrodes through an electrolyte The traditional LIB has a liquid electrolyte made of salt and organic solvents, but is prone to evaporation and can cause fires.

The electric graphene products of East lumena, "ene king", is updated to the second generation It has been applied to the electric scooter, sharing electric bicycle, electric cars, and etc, gradually extend to the new energy automotive industry.

Because of the material assets reorganization, Clou electronic (002121, SZ) suspended on May 2 But it resumed trading on May 4.

Different electric battery has different size of the modelThe lead-acid batteries of electric cars on the market can use AFTGGP module lithium battery instead of: 60 v 315 x20 size (17) X9.

According to the physics formula R = U/I, the test equipment make the lithium battery go through a large constant DC current(now generally use a 40 ~ 80 a large current) in a short period of time (generally for 2 ~ 3 seconds) , measuring lithium voltage at that time, and  calculate the lithium battery internal resistance according to the formulaThe measurement accuracy is higher, control properly, the accuracy of measurement error can be controlled within 0.

Stick with the following methods for motorcycles storage battery maintenance, the service life of the battery can be extended to five or six yearsMotorcycle battery maintenance mode is as follows:1) battery liquid surface inspection with addedMotorcycle battery liquid level must be between, on the lower limit, and never less than the lower limit, below the lower limit to complement in time.
