What are the types of power batteries

The main types of power batteries for new energy vehicles are: lithium-ion batteries, nickel-hydrogen batteries, fuel cells, lead-acid batteries and sodium-sulfur batteries.

Lithium-ion power battery: has the following advantages: high working voltage; large specific energy; small size; light weight; long cycle life; low self-discharge rate; no memory effect; no pollution, etc.

Ni-MH rechargeable battery: The Ni-MH battery can be used for fast charging and discharging process. When the car is running at high speed, the electricity generated by the generator can be stored in the Ni-MH battery on the vehicle. Plenty of gasoline.

Fuel cell: A device that directly converts chemical energy into electrical energy. Its positive electrode is an oxygen electrode, and its negative electrode is a fuel electrode such as hydrogen or hydrocarbons or ethanol.

Lead-acid battery: widely used as the starting power source of internal combustion engine vehicles. It has good reliability, readily available raw materials, and low price; its specific power can basically meet the dynamic requirements of electric vehicles.

Sodium-sulfur battery: The sodium-sulfur battery can be discharged with high current and high power. It can release 3 times its inherent energy in an instant, and the charging and discharging efficiency is high.

What are the characteristics of the power battery

1. Ultra-long life, the cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the lithium iron phosphate power battery produced by Abaige has a cycle life of more than 2,000 times, standard charging (5 hours rate) Use up to 2000 times. The lead-acid battery of the same quality is "new half year, old half year, and maintenance and maintenance for half a year", which is only 1 to 1.5 years at most, while lithium iron phosphate battery will reach 7-8 years when used under the same conditions. Taken together, the price-performance ratio will be more than 4 times that of lead-acid batteries.

2. Safe to use, lithium iron phosphate completely solves the hidden safety problems of lithium cobaltate and lithium manganate. Lithium cobaltate and lithium manganate will explode under strong collisions, posing a threat to the life safety of consumers, while iron phosphate Lithium has undergone rigorous safety testing and will not explode even in the worst traffic accidents.

3. It can charge and discharge quickly at 2C with high current. Under the special charger, the battery can be fully charged within 40 minutes at 1.5C, and the starting current can reach 2C, but lead-acid batteries do not have this performance now.

4. High temperature resistance, the electric heating peak of lithium iron phosphate can reach 350℃~500℃, while lithium manganate and lithium cobaltate are only around 200℃.

5. Large capacity.

6. No memory effect.

7. Small size and light weight.

Application field of power battery

1. Automobile and motorcycle industry: mainly to provide electrical energy for the starting ignition of the engine and the use of on-board electronic equipment;

2. Industrial power system: used in power transmission and substations, providing closing current for power units, and providing backup power and communication power for public facilities;

3. Electric vehicle and electric bicycle industry: replace gasoline and diesel as the driving power source for electric vehicles or electric bicycles.
