How much difference is the difference between electric vehicle batteries?

The voltage between the batteries and the difference in discharge amount are considered bad. If you don't discharge the amount of electricity, it will be broken if it is 1V.

It's said that it's bad, but it's actually a short run.

Many lead-acid batteries are used in electric vehicles, and lead-acid batteries have low cost and high cost performance. Because this battery can be recharged and can be used repeatedly, it is called a "lead-acid battery".

The voltage of a single battery cannot be lower than 12 volts when fully charged. The charging current of the battery is too large, which is easy to cause the battery liquid to boil, the water is gasified and discharged, and the concentration of sulfuric acid in the electrolyte increases, resulting in the accelerated corrosion of the battery electrode plate, which will affect the battery life.

There are four types of power batteries that can be used by electric bicycles, namely valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries.

Most cars have a wire loss plug left in the controller, and some car manufacturers remove the speed limiter from the factory, which can not only attract customers who value car speed, but also reduce costs, such cars are very high current at high speeds, which will seriously shorten the battery life.

Electric vehicle batteries.

At present, there are two kinds of nominal voltages for a single battery: 12V and 16V, and the nominal voltage specifications after the combination are 36 (3 12) V, 48 V (4 12 or (5 12) V, 64 (4 16) V, 72 (6 12) V, 80 (5 16) V, etc.

The single voltage of the electric vehicle battery is generally 12V, 16V, 18V, and the national standard electric vehicle.

The battery is generally 36V12Ah, 36V20Ah, 48V12Ah, 48V20Ah. Due to the national standard for electric vehicles.

There are clear requirements for the weight of the electric vehicle, and the weight of the battery accounts for a large part of the weight of the vehicle, so only 36V12Ah, 36V20Ah, 48V12Ah, 48V20Ah batteries can be installed. The 36V is made of 3 12V batteries in series, and the 48V is made of 4 12V batteries or 3 16V batteries in series.

The models of electric moped are 6-dzm -dzm -dzm -dzm -dzm -dzm-30, 8-dzm -dzm-21 and so on.

For example, the specific meaning of 6-DZM-20 is as follows: 6- represents the number of series connections in a single cell of the battery, which is a 12V battery. DZM - Sealed battery for electric mopeds. 20-2 hours rate rated capacity value, 20ah.

It's not the same size! The 48V12Ah battery is 4 small batteries, and the weight is only 34 kilograms, and the 48V20Ah battery is 4 large batteries, and the weight is 50 kilograms. The distance is not the same, the 48v12ah battery can run about 40 kilometers, and the 48v20ah battery can run about 60 kilometers.

48V12Ah battery**400 or so 48V20Ah battery is about 600.

There is no difference in performance between a 48V12A battery and a 48V20A battery. The difference lies in the capacity of the rounder. **48V20A is about 50 yuan more expensive than 48V12A.

20ah battery capacity.

8 more AH than 12AH, if the battery is discharged with 1A current, 12AH can be discharged for 12 hours, and 20AH can be discharged for 20 hours, 8 more hours of discharge; If 2A is discharged, 12Ah can be discharged for 6 hours, while 20Ah can be discharged for 10 hours, and it can be discharged for 4 hours more.

Extended Materials. About electric vehicle batteries.

How to choose.

1. Check whether the electric vehicle battery product logo is complete. Including the name of the manufacturer, product specifications and models.

Date of manufacture, trademark; Check whether the internal and external signs are consistent, especially check whether the product body has an eye-catching logo and production date.

2. Pay attention to the appearance of the electric vehicle battery. Check the cavity dust for deformation, cracks, scratches and leakage marks. Battery terminals.

The upper should be clean and free of rust, and the signs should be clear.

3. Pay attention to the rated capacity of electric vehicle battery products.

The larger the rated capacity of the battery, the longer the battery will be discharged, it is best not to buy a battery without a rating, but pay attention to whether it is dedicated to electric vehicles.

4. Buy brand batteries from well-known enterprises and large enterprises. Batteries are generally provided by professional battery manufacturers, and the quality of batteries produced by different brands and manufacturers is different, and there are also high and low. Well-known, large-scale enterprise scale.

Large, strong technology, good after-sales service, battery quality.

5. Optional battery matching, with automatic control.

Even if it's broken.

The electric vehicle battery is charged badly, not with a bad one, it can be seen that the importance of the charger and the battery matching, there are two situations: one is that the new charger itself and the battery manufacturer which stove provides the parameters do not match, the charging voltage is too high, the battery water loss is aggravated, the life is shortened, and the more serious is that the charging current can not drop the set conversion current value, the battery temperature rises, the charging current is further increased, the temperature rise is great, the thermal runaway, the battery expands and deforms, on the contrary, the charging voltage is too low, and the battery is in an undercharged state for a long time. A part of the PBSO4 has never been converted, resulting in sulfation, the battery capacity buffer decreases, and the electric moped has a shorter driving range. The second is that the quality of the components of the charger itself is poor, and when it is first used, it is still matched, and it is used in a cycle with the charging and discharging of consumers.

Due to the temperature rise of the charger itself and the aging of the components, the charging voltage and conversion current drift and the battery is damaged.

There is usually a misunderstanding about the nominal cycle life of the consumer instruction manual, thinking that the life of the battery will be reduced once it is charged, so every time the power of the battery is consumed to the protection voltage of the controller before starting to replenish the power, but this not only does not protect the battery, but also shortens the battery life. Because the positive active substance PBO2 itself is not firmly bound to each other, and the molar volume of PBO2 and PBSO4 is very different, the shallower the discharge depth, the lower the degree of shrinkage and expansion. Therefore, consumers are reminded that if possible, the battery should be replenished in time.

It is good to measure the voltage of several cells consistently, about 14 volts per battery.

The quality of the battery car, only when you are driving can you know the mileage you run is good.

If there is professional voltage testing equipment, of course, it is good to test it, but if there is no equipment, then how should consumers choose electric vehicle batteries? You can check it out from the following points.

1. Check whether the logo of the battery product is complete. Including the name of the manufacturer, product specifications and models, manufacturing date, trademarks, etc., to check whether the internal and external signs are consistent, especially to insist on whether the product itself has eye-catching logos and production dates.

2. Pay attention to the appearance of the electric vehicle battery, and check whether there are any writing, cracks, scratches and leakage marks. Whether the battery terminal is clean and corroded.

3. Pay attention to the rated capacity, voltage, weight of the battery and other key indicators. The battery is the main power source of the electric vehicle, different capacitance, power, battery weight, etc. will affect the driving distance of the electric vehicle.

I want to put a siren horn on the electric car 12v can you.

It's all 12 volts, it's just a matter of connecting a few in series.

Hello dear, the voltage of lithium batteries has a certain impact on the performance and maintenance of electric vehicles. Generally speaking, the rated voltage of lithium batteries is generally 36V, 48V, 60V, etc., and different voltage sizes correspond to different electric vehicle models. If the battery voltage of the electric vehicle does not match the vehicle model, it may lead to the performance of the electric vehicle degrading, such as not accelerating fast enough from the start, short range, etc.

When repairing an electric vehicle, if you need to replace the battery, you must choose a battery with the same voltage as the original battery, otherwise it may affect the performance of the electric vehicle. At the same time, when maintaining the electric car, it is also necessary to pay attention to the connection of the battery or the positive and negative poles to avoid the situation that the battery is reversed, otherwise it may lead to the failure or even danger of the electric vehicle.
