With the continuous improvement of the requirements for the cruising range of new energy vehicles, the trend of the development of power batteries to high energy density has become more and more obvious Whether the power battery can guarantee high-quality product performance before delivery to the customer is inseparable from the role played by the excellent battery detection system.

It is understood that China's power battery shipments in the first quarter of 2018 was 86GWh, which has an increase of 32.

The lithium battery industry has entered a new phase of rapid growth According to Japanese IIT statistics, the global lithium battery market in 2011 was about 98 billion yuan.

For electronic products, the fastest battery under normal conditions is the built-in battery Although Apple has not announced the battery capacity of Apple Watch, but from the size of this watch, its battery is certainly not very large.

The core of an electric car is the battery, while the core of the battery is in the battery management system The electric vehicle battery management system can protect the safe and reliable use of the battery, give full play to the battery capacity, improve the service life of the battery, and ensure the normal operation of the electric vehicle through a series of management and control.

1 Constant current charging.

The body battery is also a lead-acid battery system, and the gel battery is only a colloidal substance added to the electrolyte The anti-vulcanization ability and low-temperature performance of the colloidal battery are better than ordinary lead-acid batteries.

Lithium iron phosphate is not alone Dr Weifeng Fan believes that lithium iron phosphate is a complex phosphate formed by lithium and another metal ion, similar to the chemical fertilizers sold on the market (ammonium dihydrogen phosphate, ammonium ferric phosphate, etc.

The volumetric specific capacity is the capacity divided by the volume of the battery, and the mass specific capacity is the capacity divided by the mass Extending from here, the battery cost is converted to the unit capacity, that is, from the perspective of battery charge and discharge capacity.

The two "driver" batteries are energy storage batteries, solar lead acid batteries and colloidal batteries, which use the principle of cathode absorption to seal the battery When the battery is being charged, oxygen is evolved in the positive electrode and hydrogen is evolved in the negative electrode.
