What is the maximum battery of an electric car?

72v。

12ah, is the capacity of the battery, such as 1A current with electricity, it can be used for 12 hours. With 2A, it can be used for 6 hours. The larger the capacity of the battery with the same voltage, the farther the car will go. Usually the larger the size of the battery, the more expensive it is.

48V is the voltage of the battery, which is consistent with the motor and cannot be replaced at will. There are usually indicators such as 12V, 24V, 36V, 48V, etc., and the wattage of the motor is not the same, the larger the wattage, the more electricity is consumed, but the greater the power. If you just ride by yourself, you can choose a smaller wattage and run longer.

If you want to carry people or goods, you should choose a large wattage.

Precautions for electric vehicle batteries.

Do not store the battery at a loss of power: The state of power loss refers to the fact that the battery is not charged in time after use, resulting in insufficient charging and a decrease in the capacity of the battery. The longer the idle time, the more serious the damage to the battery. When the battery is not in use, it should be charged once a month, which can extend the life of the battery.

Master the charging time, the average charging time is about 8 hours. If it is shallow discharge, the battery will be fully charged quickly, and if it continues to charge, it will be overcharged, causing the battery to heat up.

Reduced battery life. Therefore, it is best to charge the battery once when the discharge depth is 60%-70% (down to two grids), and it can be converted into riding mileage when it is actually used, and the necessary charging is carried out according to the actual situation to avoid harmful charging.

The maximum battery of a two-wheeled electric vehicle is 72 volts, which is actually connected by six 12 volt batteries in series.

Generally, there are 3 in series into 36 volts, 4 in series into 48 volts, 5 in series into 60 volts, and 6 in series into 72 volts.

Each electric car battery is 12 volts, if there are three pieces, it is 36 volts, and four pieces are 48 volts. The normal theoretical standard voltage of each battery of electric vehicle battery is 12 volts, but in fact, the voltage of each battery is about volts, if there are 5 batteries, it is 60V, if there are 6 batteries, it is 72V. Electric vehicle is a simple structure of transportation, the main components of this vehicle include frame, electric motor, controller, battery.

Introduction to electric vehiclesPure electric vehicle, also known as battery electric vehicle, refers to a vehicle that is powered by a fully charged battery in advance, propelled by an electric motor, and the power of the battery is supplemented by an external power source, and meets the requirements of road traffic and safety regulations. Due to its low environmental impact compared to conventional vehicles, its prospects are widely promising.

The frame is part of an electric vehicle and the heart of an electric vehicle. The first is the pedal, for people to put their feet on the electric car when driving, there is a wind shield in front of the pedal, there are pedals next to it, and under the pedal is the battery of the electric car, we all know that the electric car can not run without the battery, and it is less convenient to run. Underneath the battery is a chain, which is used to help the battery when it is out of power.

An electric motor is installed on the rear wheel, which powers the electric vehicle and drives it for easy use.

60 volts.

The 5 batteries of electric vehicles are 60 volts, and the most common batteries used in electric vehicles are 48 volts and 60 volts lead-acid batteries, which are composed of different numbers of 12 volt batteries.

Under normal circumstances, it may be difficult to start below this voltage, and after starting, the voltage of the 12-volt train should be between the voltage of the 12-volt car system because the generator starts to generate electricity.

Within the normal range, the voltage of the car is generally between 12V-15V, as long as it is not less than 11V when starting, it is normal, usually pay attention to the maintenance of the generator, and it is best to supplement the battery (remove it to the charging place of the professional battery), which is conducive to the service life of the battery.

The power of the battery car:

The power of the battery car is determined by the voltage, that is, the greater the total voltage of the battery, the stronger the power of the battery car, and the smaller the total voltage of the battery, the less the power of the battery car. Different battery cars have different voltage and capacity specifications, and you mainly have to look at the description of the battery car to understand.

If you simply calculate the cost performance from ** and battery life, it should be more cost-effective for 60v20ah electric vehicles, but the purchase of electric vehicles should also take into account the quality of electric vehicle brands and their own needs, after all, only the most suitable products for themselves are the most cost-effective products.

Electric vehicle batteriesGenerally, it is divided into: 24V, 36V, 48V, 60V, 64V. Among them, 36V and 48V are the most common, accounting for more than 95% of all electric vehicle users; 36V is commonly used as:

36V10Ah, 36V12Ah, 48V commonly used: 48V10Ah, 48V12Ah, 48V14Ah, 48V17Ah, 48V20Ah, <>

Electric vehicle batteries

With the maturity of electric vehicle technology, not only electric vehicles have begun to become rich and diverse, but also various smart electric vehicles have entered the consumer market. At present, the batteries commonly used in electric vehicles are mainly lead-acid batteries.

Lithium battery, graphene battery.

There are 4 kinds of gel batteries, and they have their own characteristics, each with its own advantages and disadvantages.

from market share.

From the point of view, the order should be lead-acid batteries, lithium batteries, graphene batteries, and rubber dry body batteries.

From the point of view of battery**, the order should be lithium battery, graphene battery, gel battery, lead-acid battery.

From the perspective of battery life, their order should be lithium batteries, graphene batteries, gel batteries, and lead-acid batteries.

From the lead-acid batteries in the early days of electric vehicles a hundred years ago, to the lithium batteries of the rising star, there have been many batteries in recent years, including graphene batteries and gel batteries.

The voltage of the BAI battery of electric vehicles is single.

A DU is generally 12V, 16V, 18V. That is, the maximum voltage of a single one is zhi18v. Electric DAO

Cars in general. The national standard electric vehicle battery is generally 36V12Ah, 36V20Ah, 48V12Ah, 48V20Ah, and the maximum voltage of the non-standard is 96V, that is, a battery pack composed of 8 12V or 6 16V batteries in series.
