Lvxin Electric Vehicle is a comprehensive enterprise integrating scientific research, production, sales and service. In the face of market demand, Lvxin electric vehicle products continue to expand, continuous innovation, and the introduction of advanced technology, talents and management experience, has a strong team of R&D personnel and management personnel.

Now the temperature plummets in winter across the country, and the electric patrol car in daily use, if it is not properly maintained, it may cause some damage to the battery of the electric patrol car, affecting the service life and mileage of the battery. The following [Lvxin Electric Vehicle Official Website] will teach you how to maintain an electric patrol car in winter.

1. First of all, we should strengthen the maintenance of electric patrol cars, reduce the various conditions of each component because of the special environment, and we need to focus on the inspection and maintenance of its battery, motor and controller.

2. In rainy and snowy weather, we try to minimize the frequency of use of electric patrol cars, because in this weather environment, if electric patrol cars are used for a long time, it is very easy to cause water ingress into their lines and motors, and eventually lead to short circuits.

3. The tire pressure of the electric patrol car will change with the change of temperature, and the tire pressure should be measured when the car runs for a period of time to cool down when the tire is cooled in winter, and it is best to do it at room temperature. In winter, you can increase the tire pressure appropriately.

4. The electric patrol car should be parked in an indoor place with a relatively moderate temperature, because when it is parked in a lower temperature environment, it will not only damage its battery, but also cause corrosion to its body appearance.

5. Recently, the haze phenomenon in various regions is serious, and the visibility is low in this weather environment, so for the sake of safety and reduce the occurrence of traffic accidents, we must slow down when using electric patrol cars, and we also need to turn on double flashes if necessary.

6. Increase the charging frequency of the electric patrol car, the battery capacity will be reduced in the case of low temperature in winter, and it is very easy to automatically discharge, so at this time we must increase our charging frequency to prevent the battery from losing power.

7. Scrub and clean the electric patrol car from time to time, and the dirt attached to the car body in winter is very prone to freezing, and long-term non-cleaning will not affect its appearance, and it also causes damage to the appearance surface.

1. It is strictly forbidden to lose electricity during storage.

It is strictly forbidden to be in a state of power loss when the battery of the patrol car is stored. The state of power deficit refers to the fact that the battery is not charged in time after use. When the battery is stored in a state of power loss, sulfation is easy to occur, and the lead sulfate crystals adhere to the plates, which will block the ion channel, resulting in insufficient charging and a decrease in battery capacity.

The longer the battery is idle, the more damaged the battery will be. Therefore, when the battery is not in use, it should be replenished once a month, so as to better maintain the health of the battery.

2. Regular inspections.

In the process of use, if the driving range of the electric vehicle suddenly drops significantly by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has a problem. At this time, you should go to the sales center or the maintenance department of the first merchant in time for inspection, repair or matching. This will extend the life of the battery pack and save you the most money.

3. Avoid high-current discharge.

When the patrol car is starting, carrying people, and going uphill, try to avoid stepping on the acceleration as much as possible, forming an instantaneous high-current discharge. High-current discharge can easily lead to lead lead crystallization, which can damage the physical properties of the battery plates.

Fourth, correctly grasp the charging time.

In the process of use, the charging time should be accurately grasped according to the actual situation, and the charging frequency should be grasped with reference to the usual frequency of use and mileage. When driving normally, if the power gauge indicates red and yellow lights, it should be charged; If only the red light is on, it should stop running and charge as soon as possible, otherwise the over-discharge of the battery will seriously shorten its life. After a full charge, the running time is short, and the charging time should not be too long, otherwise it will form an overcharge and make the battery heat.

Overcharging, over-discharging, and under-charging can all shorten battery life. In general, the average charging time of the battery is about 10 hours. If the battery temperature exceeds 65 during the charging process, the charging should be stopped.

5. Prevent sun exposure.

Patrol cars are strictly forbidden to 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, causing the battery activity to decline and accelerate the aging of the plates.

6. Avoid hot plugging hair while charging.

Loose 220-volt power plug or charger output plug of patrol car, oxidation of the contact surface and other phenomena will cause the plug to heat up, and too long heating time will lead to a short circuit or poor contact of the plug, damage to the charger and battery, and bring you unnecessary losses. Therefore, when the above situation is found, the oxide should be removed or the connector should be replaced in time.

7. Cleaning of electric vehicles.

The cleaning of the patrol car should be in accordance with the normal car washing method, and attention should be paid to avoid water flowing into the charging socket of the car body during the cleaning process to avoid short circuit in the body line.

In the following cases, the paint layer will peel off or the body and parts will corrode, and the vehicle must be cleaned immediately.

When driving along the coast;

When driving on a road sprinkled with antifreeze;

When it is stained with grease and other debris;

When driving in an area where the air contains a lot of dust, iron filings, or chemicals;

Manual cleaning of electric vehicles.

In a cool place, wait for the body temperature to drop below 40 degrees Celsius before washing.

Flush loose dirt away with a hose;

Lead-acid battery is the main battery used in electric patrol cars, the battery is not bad but charged, by no means alarmist, the battery charging performance of the battery maintenance and service life and performance of electric vehicles play a pivotal role, must be paid attention to.

1. The depth of discharge of the battery has a great impact on the cycle life of the battery, because the deeper the depth of discharge, the greater the expansion and contraction of the electrode, and the more the active material of the positive electrode falls off, thus losing the discharge characteristics and decreasing the performance until the end of life. Therefore, the battery should be used to avoid deep discharge as much as possible, so that shallow discharge and frequent charging, the general situation should be: the battery is best charged once when the discharge depth is 50%-70%.

2. After the battery is discharged to the termination voltage, continuing to discharge (over-discharge) will seriously damage the battery, because it is easy to form irreversible sulfation at this time, so that the charging recovery ability becomes poor, or even cannot be repaired. Therefore, the battery should be used to prevent over-discharge, and "under-voltage protection" is an effective measure. The "under-voltage protection" measure is controlled by the electric vehicle controller, but because the electric vehicle meter and indicator light and other power-consuming appliances are not controlled by the controller, so the electric vehicle lock will start to use electricity once it is closed, although the current is small, but if it is discharged for a long time, the battery will be over-discharged.

Therefore, the lock should not be opened for a long time and should be turned off immediately when not in use.

3. The charging current should be less than or equal to the charging current that the battery can accept, otherwise, the excess current generated by overcharging will make the electrolyzed water liquid consume too quickly, and produce a serious gas separation phenomenon, which will make charging very difficult for a long time, so prevent overcharging as much as possible when charging. Chargers from legitimate manufacturers ensure that the battery is not overcharged.

4. Lead-acid batteries are especially afraid of discharging at a loss of power, and the battery will be permanently damaged if placed for 3-7 days, so please charge the battery as soon as possible after use. For batteries that have not been used for a long time, the battery should be charged every 15 days or so to compensate for the loss of self-discharge power when the battery is stored.

5. The battery of the electric patrol car runs in the high temperature season, and there is mainly the problem of overcharging. 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 sun, and should be kept away from heat sources. In the case of low temperature, charging mainly has the problem of poor charging acceptance capacity and insufficient charging, resulting in battery power loss.

Thermal insulation and anti-freezing measures should be taken at low temperatures, especially when charging, which should be placed in a warm environment, which is conducive to ensuring sufficient electricity, preventing irreversible sulfate, and prolonging the service life of electric vehicle batteries.

Electric patrol cars should pay attention to check whether the vehicle is in good condition before use, such as whether the tire pressure is sufficient, whether the front and rear brakes are sensitive, whether the vehicle is abnormal, whether the screws are loose, and whether the battery is sufficient. When the electric patrol car is just started, it should be accelerated slowly to avoid instantaneous rapid acceleration and damage to components. In order to prolong the life of the battery and motor, the foot pedal assist is applied when the electric patrol car is started and climbed.

On the premise of ensuring safety, frequent braking and starting should be minimized during driving to save electric energy. When charging, you should pay attention not to use other brands of chargers, each brand of chargers is matched with the performance of the battery, only a dedicated charger can achieve the best charging effect. The charger contains a high-voltage line, do not disassemble it without authorization.

When charging the electric patrol car, the charger should not be covered with any items, and should be placed in a ventilated place, while paying attention to prevent liquids and metal particles from entering the inside of the charger to prevent falling and impact, so as not to cause damage.
