When the battery is not connected to the external circuit, the battery capacity loss caused by the internal spontaneous reaction is the self-discharge of the battery Among all the power battery types, the nickel-hydrogen battery has the largest self-discharge, and the ordinary nickel-hydrogen battery reaches the self-discharge rate of 30%.

Ni-MH battery charging, if the current is different, the charging effect and the impact on the power battery will have a big differenceThe expression of the charging current is the concept of magnification, which is numerically equal to the ratio of the charging current to the battery capacity, and the unit of measurement is mA.

Today, the industry has passed the era of lead-acid batteries and nickel-cadmium batteries, and is currently in the era of green batteries for nickel-metal hydride batteries and lithium-ion batteries Nickel-metal hydride battery VS lithium battery is the real life? On June 25, 2009, the Ministry of Industry and Information Technology issued the "New Energy Vehicle Manufacturing Enterprise and Product Access Management Rules", which was officially implemented on July 1.

Basic requirements for lithium battery transportation: (1) Lithium batteries and lithium battery packs are classified as Class 9 dangerous goods; (2) All lithium batteries (groups) shall pass the UN383 test; (3) Exceptional provisions for the transportation of some Class 9 dangerous goods lithium batteries; (4) Strict restrictions on transport samples; (5) Restrictions on daily-use lithium batteries carried by passengers; (6) All defective batteries or damaged batteries are prohibited from being transported.

(CN) - As global demand increases, the mineral resources needed to make batteries can become tight, but researchers at the Georgia Institute of Technology say they may have found a viable alternative to traditional lithium battery construction Scientists at Georgia Tech say new research suggests that batteries made with potassium and sodium are promising – and perhaps even better than lithium – for battery storage.

In recent days, solid-state batteries have become a hot topic in the battery industry The source is that a few days ago, the US company Fisker Motors released a new battery technology - solid-state battery, said to increase the mileage of electric car users to 500 miles (about 804 km) or more, charging time is only 1 minute .

As the temperature decreases, the mileage of new energy vehicles is affected more or less Although the phenomenon in this industry has been accepted by consumers, how much do you know about how to effectively extend the mileage of new energy vehicles in the winter? In fact, through good car habits, it is equally easy to open a new energy car in winter.

Calculation method of battery capacity (C): Capacity C = discharge battery (constant current) I × discharge time (hours) T In turn: Discharge time T = capacity C / discharge current (constant current) I For example, if a battery is discharged with a constant current of 500MA (mA) for 2 hours, then the capacity of this battery is equal to 500MA*2H=1000MAH=1AH If a battery is discharged for 2 hours with a current of 5 amps, then the capacity of the battery is 10 AH.

If you charge 1300mAh to 17H to be full, then you charge 2400mAh theoretically for 32 hours For the same battery, the longer the charging time of the charger the better the protection of the battery.
