  Electric patrol car is a specially designed and developed model for special department personnel to patrol instead of transportation
This model is divided into ordinary patrol car and sealed car
Ordinary patrol car can be divided into ordinary car and luxury car
The electric vehicle is especially suitable for public security patrols, pedestrian streets, golf courses, tourist attractions, real estate (garden communities), large enterprises, government units, parks, entertainment places, stadiums, colleges and universities, hospitals, sanatoriums, stations, airports, wharves and other means of transportation
Electric patrol car is not only the first choice for police mobile patrol, but also a good helper for urban management and other law enforcement departments

It adopts superior automobile chassis technology, independent suspension system, high-strength tempered glass, and pays more attention to practicality
It integrates police systems and tool kits such as alarm lights and pagers, and provides mobility and dexterity for street patrol tasks

Introduction to the whole vehicle intelligent, efficient and talkative intelligent electric patrol car is a green police car with high efficiency, energy saving, low noise and zero emission
With voice device, using battery,
The maximum speed is 40 km and the maximum driving range is 80-120 km

Electric patrol cars have many advantages, low price (the price of each car ranges from 38000 to 60000), environmental protection and energy conservation (the cost per hundred kilometers is more than 2/3 cheaper than that of gasoline vehicles), and low noise
When used in urban patrol, it can not only greatly save fuel costs, but also improve the rate of seeing police on the street and the density of street patrol
In addition, it is more convenient to get on and off the bus than ordinary cars and has a broader vision [1] 
As for a friend who said that private cars were for public use, he was actually a little too worried
Compared with traditional vehicles, electric patrol cars are not suitable for private cars (unless our police dare and are willing to use open small patrol cars to ride their wives, children or daily necessities through the streets)

If electric patrol cars are purely furnishings, are so many electric cars on the street furnishings? Unless you buy it and don't use it, as long as you use it, it's not a decoration

Isn't it good to equip electric patrol cars to patrol streets and other public places and establish a more reasonable, efficient and people-friendly security patrol system? Is it a good thing or a bad thing for the people? As long as the money spent is reasonable, legal and right, why not spend it? We can tolerate the public authorities spending money and doing things that should not be done, but we can not tolerate the public authorities spending money and doing things that should be done? When equipped with * patrol cars, of course, a set of more suitable urban patrol system must be equipped
Everyone is opposed to wasting people's wealth, indiscriminately adding hardware and ignoring the construction of relevant software
Some even take advantage of this opportunity to seek illegitimate interests
At the same time, only by establishing a constantly improving software and hardware measures can we make our society more harmonious, peaceful and beautiful
Perhaps, we have not been able (mainly referring to the financial resources) to buy electric patrol police vehicles, but we absolutely cannot say that we have neither the ability nor the obligation to seek a more perfect urban patrol system

Advantages features the electric patrol car has many advantages, environmental protection and energy saving (the cost per hundred kilometers is more than 2/3 cheaper than that of gasoline vehicle patrol), which can greatly save fuel costs
At the same time, it has the characteristics of low noise, dexterous mobility, fast speed-up, long driving range, strong carrying capacity, wider vision and easy patrol
It can also help to improve the street alarm rate, increase the density of street patrol, and become a mobile patrol As a good helper of urban management and law enforcement, many communities, large enterprises, government agencies, parks, colleges and universities, stations, airports, wharves and other units have widely used this type of vehicle for public security patrols
The maximum speed of the DC electric patrol car is 35 km / h, and the maximum driving range of a single charge is 80 to 100 km
The maximum speed of variable frequency electric patrol vehicle can reach 45 km / h, and the maximum driving range is 100-120 km

Tire maintenance the tire of the electric patrol car is an important component
During the daily inspection of the electric patrol car, it is necessary to check whether the tire is normal and pay attention to maintenance

The use of excessively worn or inadequately inflated tires is likely to cause crash accidents, which will seriously threaten the personal safety of passengers
The important causes of tire damage are: the impact of the road edge, the jumping on the pit, the unexpected obstacles in the collision, and the frequent driving on the bad road
Try to avoid these situations when driving

Visual inspection regularly check whether the tire is damaged, and remove any embedded objects (stones, metal parts, etc
) that may penetrate the carcass, which may seriously damage the carcass
If there are protruding parts and uneven places on the bottom and side of the tire; There are cuts, splits and cracks on the bottom surface of the tire; The underside of the tires is excessively worn
Replace these tires
If you are not clear about the past condition of a tire, do not install it
You must have your old tire checked by a professional to make sure that you can continue to use it

Inflation properly inflates the tire, so that the handling and driving can reach an ideal level, and the service life of the tire can be extended at the same time
Excessive or insufficient inflation not only threatens safety, but also causes uneven wear, makes your driving more unstable, and is more likely to be damaged due to overheating
Under inflation will cause the battery to consume more power

It is recommended that you check your tires visually every day and check the air pressure with a barometer at least once a month
Please check the tire pressure when the tire is cold (three hours after parking)

Battery lead-acid battery is the main battery used by electric vehicles
The battery is not used but charged
It is not alarmist
The charging performance of the battery plays a decisive role in the battery maintenance, service life and performance of electric patrol vehicles, which must be paid attention to

1
The discharge depth of the battery has a great impact on the cycle service life of the battery
This is because the deeper the discharge depth, the greater the expansion and contraction of the electrode, and the more the active material of the positive pole falls off, thus losing the discharge characteristics and reducing the performance until the end of the service life
Therefore, deep discharge shall be avoided as far as possible when using the battery, and shallow discharge and frequent charging shall be achieved
Generally, it is best to charge the battery once when the discharge depth is 50%-70%

2
After the battery is discharged to the termination voltage, continued discharge (over discharge) will seriously damage the battery,
This is because it is very easy to form irreversible sulfation at this time, so that the charging recovery capacity becomes poor and even can not be repaired
Therefore, over discharge shall be prevented when using the battery, “ Undervoltage protection ” Is an effective measure& ldquo; Undervoltage protection ” The measures are controlled by the electric vehicle controller
However, since the electric vehicle meters, indicator lights and other electric consumers are not controlled by the controller, the electric vehicle lock will start to use electricity once it is closed
Although the current is small, if it is discharged for a long time, the battery will be over discharged
Therefore, it shall not be used for a long time * and it shall be turned off immediately when not in use

3
The charging current shall be less than or equal to the acceptable charging current of the battery
Otherwise, the excess current generated by overcharging will cause the electrolytic water to be consumed too quickly and cause serious gas evolution
It will become very difficult to charge for a long time
Therefore, overcharging shall be prevented as much as possible during charging
The charger produced by the regular manufacturer can ensure that the battery is not overcharged

4
Lead acid batteries are especially afraid of discharging due to power loss
If the battery is stored for 3-7 days, it may be permanently damaged
Therefore, please charge the battery as soon as possible after use
For the battery that is not used for a long time, the battery shall be charged every 15 days or so to compensate for the loss of self discharging power when the battery is stored

5
The battery of electric vehicles mainly has the problem of overcharge when it operates in high temperature season
Therefore, in summer, the temperature of the battery should be reduced as much as possible to ensure good heat dissipation, prevent charging after exposure to the hot sun, and keep away from the heat source
At low temperature, the main problems of charging are poor charging acceptance and insufficient charging, resulting in battery power loss
Heat preservation and anti freezing measures shall be taken at low temperature
In particular, it shall be placed in a warm environment during charging, which is conducive to ensuring sufficient electricity, preventing irreversible sulfation and prolonging the service life of electric vehicle batteries

Power loss during maintenance and storage is strictly prohibited
The battery of the electric patrol car shall not be in the state of power loss during storage
Power loss state means that the battery is not charged in time after use
When the battery is stored in the power loss state, sulfation is easy to occur
The lead sulfate crystal is attached to the electrode plate, which will block the electric ion channel, resulting in insufficient charging and reduced battery capacity
The longer the power loss state is idle, the more serious the battery damage is
Therefore, when the battery is idle, it should be recharged once a month, so as to better maintain the healthy state of the battery

Periodic inspection
During use, if the driving range of the electric vehicle suddenly drops by more than ten kilometers in a short time, it is likely that at least one battery in the battery pack has a problem
At this time, it is necessary to timely go to the sales center or the agent maintenance department for inspection, repair or assembly
This can relatively prolong the service life of the battery pack and save your expenses to the greatest extent

Avoid high current discharge
When the electric patrol car starts, carries people and goes uphill, try to avoid stepping on it violently to accelerate, resulting in instantaneous large current discharge
Large current discharge can easily lead to lead-acid crystallization, which will damage the physical properties of battery plates

Correctly grasp the charging time
During use, the charging time shall be accurately grasped according to the actual situation, and the charging frequency shall be grasped with reference to the usual use frequency and driving mileage
During normal driving, if the red light and yellow light of the electricity meter are on, it should be charged; If only the red light is on, stop running and charge as soon as possible, otherwise the battery life will be seriously shortened due to excessive discharge
After being fully charged, the battery will be charged after a short operation time
The charging time should not be too long
Otherwise, overcharging will occur and the battery will heat up
Overcharge, overcharge, and undercharge can shorten battery life
Generally, the average charging time of the battery is about 10 hours
If the battery temperature exceeds 65 ℃, the charging shall be stopped

Protect against sun exposure
Electric patrol cars shall not be exposed to the sun
The environment with too high temperature will increase the internal pressure of the battery and cause the battery to lose water, which will lead to the decline of battery activity and accelerate the aging of the electrode plate

Avoid heating the plug when charging
Loose 220 volt power plug or charger output plug of the electric patrol car, oxidation of the contact surface and other phenomena will cause the plug to heat up
A long heating time will cause short circuit or poor contact of the plug, damage the charger and battery, and bring you unnecessary losses
Therefore, in case of any of the above conditions, the oxide shall be removed or the connector shall be replaced in time

Cleaning of electric vehicles
The electric patrol car shall be cleaned according to the normal car washing method
During the cleaning process, attention shall be paid to avoid water flowing into the car body charging socket and short circuit of the car body circuit

Under the following circumstances, the paint layer will peel off or the body and parts will be corroded
The vehicle must be cleaned immediately

--When driving along the coast;
--When driving on the road with antifreeze;
--In case of grease and other sundries;
--When driving in an area with a large amount of dust, iron filings or chemicals in the air;
Manual cleaning of electric vehicles
In a cool place, wait until the body temperature drops below 40 degrees Celsius before cleaning

--Use a water pipe to wash away loose dirt;
--Clean the vehicle with neutral car washing agent
The mixture of cleaning agent shall be carried out according to the manufacturer's instructions
Soak the cleaning solution with a soft cloth without
