What to look out for when buying an electric car

1. Electric vehicle model. The choice of model should be determined according to the actual situation of the rider. In addition, the choice of model should also be considered according to the rider's storage situation. If the storage space is narrow, try to buy a lighter one. If you need to shop and pick up children from school on a daily basis, you should also consider the convenience of passengers and cargo.

2. Choose a good configuration. Electric vehicles have four major parts, namely motor, battery, charger and controller, which are the key to the performance of an electric vehicle.

3. The power of the motor is very important. If the power is too small, the load, speed, acceleration and climbing capabilities are limited. In particular, the climbing ability is directly related to the power of the motor. If it is too large, it will not only waste electricity, but also increase the cost of buying a car. Therefore, try to choose a motor that matches your daily use. The warranty period of the motor dealer is not the key, but the brand and performance of the motor.

4. The battery is the power of a car. The capacity of the battery is related to the endurance of the electric car, that is, how far you can run each time you go out. Therefore, try to choose a large-capacity battery and a brand battery with a good reputation.

5. Charger. Some chargers are very inconvenient for emergency travel. Therefore, try to choose a dedicated charger with overcharge protection, which can automatically stop charging when fully charged to reduce charging trouble. In addition, the charger should also be easy to carry. It can be carried in the car, but protective measures must be taken when carrying it in the car to prevent the charger from being damaged by vehicle bumps.

6. Controller. The controller equipped with a speed control handle (or speed control pedal) makes the motor speed control easy, that is, the vehicle speed can be adjusted at will according to the driver's wishes. The controller also has many additional functions: current limiting protection, undervoltage protection, soft start function, anti-runaway function, fault self-diagnosis function, etc. Not all speed regulators on the market have these additional functions, so pay special attention when purchasing.

How to maintain electric vehicles

1. The new electric vehicle should be fully charged before use.

2. Keep the battery dry and clean: frequently remove dust and dirt from the battery cover, and keep the battery dry and clean to prevent the battery from self-discharging.

3. The battery must be firmly installed on the electric bicycle: When the battery is taken down for charging, it must be firmly installed on the electric bicycle to prevent the battery from being damaged by vibration during riding. When transporting the battery, it is forbidden to drop, roll over, or press heavily.

4. Use pedals when starting: When starting an electric bicycle, you should use pedals. If there is no pedal, you can push the ground with your feet to help start it. When going uphill, use pedals to help the electric bicycle go uphill to avoid damage to the battery due to excessive discharge current.

5. Develop a good habit of charging the battery every night: Never leave the battery in a state of insufficient power for a long time, and develop a good habit of charging the battery every night. If it is not used for a long time, it should be fully charged, placed in a cool and dry place, and charged regularly, usually every 10 days.

How many kilometers can an electric car ride?

1. A motorcycle-type electric vehicle with a 48V 20A battery can generally run 60km to 80km. If it encounters winter temperature and environment, some of the power cannot be discharged and it cannot run 60km. Only a 95V battery can run 100km.

2. Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Electric vehicles are usually referred to as vehicles that use batteries as energy sources and convert electrical energy into mechanical energy through controllers, motors and other components to control the current size to change the speed.

3. The first electric car was manufactured in 1881 by French engineer Gustave Truffaut. It was a three-wheeled vehicle powered by a lead-acid battery and was driven by a DC motor. Today, electric cars have undergone tremendous changes and come in a variety of types.

4. Electric vehicles can be divided into the following categories according to the number of tires and structural type: electric bicycles, electric motorcycles, electric unicycles, electric four-wheelers, electric tricycles, and electric scooters; according to the power source: pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, and fuel cell vehicles.
