Now riding more and more people riding electric vehicles, riding electric vehicles to travel want to have a long range, can be used for a day, but many people do not know, electric vehicle power display has two ways to view, one is common, like a battery one grid one grid display, the other many car owners do not know how to use? Today, to talk about these two small problems, car owners understand the power mastery method, can accurately grasp the power, what time is needed to charge? How many roads can it run to make the battery durable.
There are several ways for car owners to look at the electricity, and the methods do not affect travel
Many car owners observe the electric vehicle power display, only a kind of battery to see the fuel gauge shows a few blocks of electricity, many times also look wrong, some people are turned on the power to observe, that is, there is a virtual power, inaccurate, the car walks up to watch accurately.
First, open the key to see the power, many car owners use this method, every time you observe how much power is left, open the key to see the table is generally full, it has a lot of virtual power, if the observation is not accurate, not charged in time, riding how far there is no electricity.
The second is to ride by feeling, some car owners generally do not observe the fuel gauge display from time to time, but by feeling charged once the electric energy to ride for a few days, with this method to charge the new battery, this method is still very practical, but the battery is used in the later stage often this method is not enough, there is a great uncertainty in the power display, the decline of the battery storage is reduced, the endurance will be reduced, slowly not charged in time, to the halfway out of power.
Electric vehicle fuel gauge 2 ways to correctly observe the power display
Method 1: The number of battery cells in the fuel gauge is displayed
Usually the number of cells shows 4 or 5 cells, calculated by the number of 100, the amount of power per cell is 25%, such as 60V displayed on the controller, it has an undervoltage value next to it is the lowest voltage 52V, when the power drops to 52V, the battery appears undervoltage, the car will not go.
Many car owners do not understand this, often a few blocks of electricity left need to be charged, they plug in the charger to charge.
This method of observation is correct, some car owners habitually turn on the power, without starting to watch the battery level display how many boxes are left? This battery display is inaccurate.
Method two, the fuel gauge digital display
The mainstream electric two-wheeler installed battery on the market is 48V, 60V, 72V, electric vehicles have a controller to control the highest voltage and the lowest voltage score, when the battery voltage drops to the lowest voltage value, the controller will stop working, protecting the battery deficit. Many electric vehicles sold in recent years have two kinds of power displays, one is the number of cells in the form of batteries, and the other is a voltage digital display.
Take you to know how much is the full power of 48V, 60V, and 72V? When do I need to charge?
48V electric vehicles, there are 4 pieces of 12V. Battery series composition, the lowest voltage of electricity consumption is 42V, full charge is 52.7 ~ 54.7V, the power drops to 46V The basic car does not go, the number of discharges is too low, and the voltage drops to two blocks, that is, 30% or less of the charge is good.
60V electric vehicle, is composed of 5 blocks of 12V, rated voltage 60V, undervoltage protection value of 52.5V, full charge display 72V, the power drops to 55V basically does not go, charging method power display remains two blocks, the voltage number drops to about 58V to charge
72V electric vehicle, is made of 6 batteries in series, undervoltage protection value of 63V, full charge display is 81V, single voltage drop to 65V basically does not go.
Figured out the minimum voltage value of 48V, 60V, 72V and fully charged display voltage, we can ride up in the electric vehicle to observe the LCD fuel gauge voltage number drop to what extent, according to the minimum voltage of each model of electric vehicle to see when to charge.
3 charging methods, not afraid to worry about electric vehicles running far
The full voltage of the 12v battery is 13.5v, the minimum limit voltage is 10.5v, if the power display is 4 cells of electricity 11÷4 is about equal to 3V, the voltage drops by 3V, the power display will extinguish a grid, if two lights are extinguished, it will drop the power by 60%, which is a law of battery power drop.
We have mastered this law, the owner of the car travel brings benefits, when our meter is blurred or the table is not clear, there is no change, we need to look at the digital voltage.
Method one: the electric vehicle walks up to observe how many cells are left of the power, and then the vehicle rides up and then looks at the power change, leaving three or two boxes, at this time to judge whether to charge in time? Universal charging is good to start charging when the battery drops below two blocks.
Method two: look at the voltage digital change in time to charge, many liquid crystal instruments, there is a battery shape of the power display, there is a voltage digital display, accurately look at the voltage negative value change, to wait for the car to start up and then observe the accurate, such as like 60V electric vehicle full charge display about 72V, drop in about 58V need to charge.
Method three: fully charged to see the mileage or riding days, this way of observation is the new battery is more accurate, the general new battery charging time in about 10 hours, like a short road to work riding for 3 days, such as 60V20Ah battery, fully charged maximum range of about 60 kilometers, you can roughly calculate, how many times a day back and forth to work how many miles? You can grasp when you need to recharge.
Summary: Some owners have a good grasp of the electric vehicle power to what extent, are riding up to see the change of power, to arrange when to charge, but some people, he is only roughly based on the feeling to arrange charging, the use of this method will have charging, diligent charging phenomenon, a long time battery will decline early, the battery is used down without accurately grasping the charging time of the electric vehicle durability.
