What are the battery types? Several kinds of batteries are briefly introduced

Batteries are the power source of electric cars. The types of battery can be roughly as follows: lead-acid battery, nickel metal hydride battery, nickel metal hydride batteries, Lithium ion batteries, nickel-cadmium batteries, sodium sulfur battery, nickel zinc battery, zinc air battery, flywheel battery.

First, according to the purpose of the lead-acid battery can be divided into:

1, the start type battery: mainly used in automobiles, motorcycles, ships, ship, etc.

Such as: 6 - QA-60AHQ- start with.

2, small traction battery: mainly used in electric vehicles, small electric tricycle.

Such as: 6 - DZM - 10 ah

3, traction type battery: used for electric vehicles, storage battery, battery car, industrial and mining electric locomotive power supply, etc.

Such as: 6 - DA - 150- d - electric motor.

Start the battery is a large current instantaneous discharge, traction battery needs stable constant current exile. The starting current of a typical car is three times the nominal capacity of the battery, and that of an electric car is generally between 5A and 20A.

Second, according to the performance of the lead-acid battery can be divided into:

1, dry charged battery: plate in dry state has been fully charged battery. Such as: 6 - QA - 100 type battery.(mainly used in the car)

2, not dry charged battery: plate in half dry battery charging status. Such as: 6-135 - j - Q type battery.(mainly used in vehicles and ships, engine, etc.)

3, maintenance-free battery: With low antimony alloy, only a small amount of maintenance is carried out during the service period, that is, the water addition period is extended. Such as: 55 b24lmf type battery.(mainly used in small cars)

4, Maintenance-free battery: battery that requires no maintenance or addition of pure water in use. (Liquid rich)Such as: 6-'ve - 54 type battery (mainly used in small cars)

5, Valve-controlled sealed maintenance-free battery: the adsorption type superfine fibre glass plate and negative plate over design of active material. Such as: MSE - 500 type battery.(mainly used in electric bicycles, UPS backup power)

Lead-acid battery

Lead-acid battery is called sealed maintenance-free lead-acid battery, its advantages are low price, large capacity, more mature technology. Especially in recent years, battery manufacturers have made new breakthroughs in battery performance and greatly improved the service life of batteries through process reform, optimization of formula and progress in charging technology. Lead-acid battery is also the main power source of electric vehicles on the market at present. The ointment is that the lead-acid battery is a bit heavy.

The lithium battery

Lithium battery is a kind of battery which is made of lithium metal or lithium alloy as negative electrode material and USES non-aqueous electrolyte solution. The advantage of lithium battery is small and light, compared with the traditional lead-acid battery more efficient, safe, environmental protection. The lightness and durability of lithium batteries also make electric cars more beautiful and light, which is very suitable for the elderly and women friends. The disadvantage of lithium batteries is that they are slightly more expensive.
