- Q:New electric cars to maintain, such as the speed of cycling. Charge。 The new chain needs no oil.
- Protect the charger.The general instructions for use include instructions on how to protect the charger. Many users do not read the instructions of the habit, often in addition to the problem after thinking of looking for instructions, often too late, so the first look at the instructions is very necessary. In order to reduce the cost of the charger, now basically no design, high vibration resistance so that the charger is generally not on the electric bicycle and bicycle in the trunk. Special circumstances, you must move, but also the charger wrapped in foam plastic, to prevent vibration bumps. Many chargers after vibration, the internal potentiometer will drift, so that the entire parameter drift, resulting in abnormal state of charge. In addition, the need to pay attention to when charging is to maintain the ventilation of the charger, otherwise, not only affect the charger's life, but also may occur thermal drift and affect the charging state. This can cause damage to the battery. Therefore, it is also important to protect the charger.
- Q:Electric car precursor safety or after drive safety?
- Certainly after flooding than the precursor well, especially the weight of the lighter, if the front is too heavy if vehicle steering is not easy to use, and when the brake brakes are easy to fall before the fall, when you brake after the brake due to light weight easy to slip behind the brake motor (to know there are certain weight); driving performance is also relatively poor.
- Q:How to choose an electric car? What should I pay attention to when I buy it?
- There are two kinds of electric bicycles: brushless and brush motors. At present, brushless permanent magnet motors have the tendency to replace brush motors. The controller must have the functions of stepless speed regulation, undervoltage, overload and power-off protection, and also has an electric quantity display device. Charger should have automatic equalization charging function, generally observed from the plug for the four core, can be achieved after charging three sets of battery voltage consistent, so as to improve the capacity of the battery.
- Q:All the questions about electric cars
- Controller fault (brush) (2) Troubleshooting: speed control, if normal, indicating that the controller is normal, you should check the speed control, and the ground. Disconnect the speed control, the car still does not stop, then the controller is damaged, replace the controller. If a power supply wheel will turn, increasing speed is very fast, commonly known as "speed", the majority of the turn of the ground contact is caused by bad cycle. Therefore, the key to check the turn to the ground. 8, instrument panel no power display, motor operation is normal (1) fault reason: instrument positive and negative lead wire, no voltage, lead or connector short circuit. Instrument damage. (2) Troubleshooting: use the multimeter DC 50V files, detect positive and negative voltage instrument. If the voltage is normal, the instrument is damaged. Without voltage, wires or connectors are broken open, and cables and connectors are checked. 9, the instrument voltage shows normal, speed display abnormal, motor operation is normal (1) failure reason: instrument damage. Speed signal line (black / white) short circuit. The controller has no speed display. (2) Troubleshooting: brush and brushless 48V: using a multimeter voltage blocking detection speed signal line and a power supply cathode (48V brushless speed signal detection and negative) between the two potential with the motor speed, the voltage varies from low to high (36V models have 0 ~ 36V change, 48V brush 0 the change of 48V ~ 48V brushless, it varies from 0 to 25V). If there is no change, check whether the speed signal line plug is normal or not Is there a short circuit? If the voltage change is normal, it belongs to the instrument fault, for example, the speed display is low. The speed adjustment potentiometer can be adjusted to the normal by the screwdriver. 36V brushless: first check the instrument panel and controller speed line (black / white), the connection line is short circuited
- Q:The difference between a lithium battery electric vehicle and an ordinary electric vehicle
- Pollution: the use of lithium batteries is pollution-free, and lead acid batteries contain lead and acid, which may cause pollution to the environment, such as throwing the batteries directly into the rubbish heap (but it seems that people are reluctant to part with it) ;5, there are a lot of differences, such as: charging characteristics, current characteristics and not too easy to ordinary consumers no longer;The current lithium battery a barrier is important to safety - explosion, although many enterprises have more stable promotional products, but a similar situation continues to appear, including mobile phone battery explosion dead and occurrence of electric vehicle lithium battery capacity is far greater than the cell phone battery explosion, as can be imagined, I believe there will be a great the market space of lithium battery near future to solve the security problem and price problem.
- Q:EABS brake principle of electric bicycle, is the brake depth good or small?
- And the main features of EABS system(1) different from the former mechanical brake, the EABS system has a new idea of braking control. When there is a braking signal, the electric wheel hub is braked immediately, and the faster the braking effect is, the more obvious the braking effect is.(2) EABS electronic brake system does not consume battery power, on the contrary, in the braking moment and downhill brake will produce short-term return on the battery charge, although the short action time, but for the battery plate can play a protective effect, prolong the service life of the battery.EABS depth adjustmentThe user can according to their own brake depth riding comfort level to adjust the EABS, can be realized from the weakest to strongest adjustment, adjustment method: first press the brake handle, and then turn on the switch lock, and then turn from the lowest to the highest, and then began to go down from the peak regulation, if the high release lever. When the brake EABS maximum depth, with the downward adjustment to release the brake, the brake depth of EABS will be reduced, the EABS depth adjusted automatically stored in the microcontroller.
- Q:What does "48v12AH" mean?
- The rated capacity (Capacity) of a battery reveals its ability to convert chemical energy into electrical energy. It is a unique parameter for battery products. From the capacity unit of A (ampere) H (hour), it is related to current and time. If the 1A (An Pei) current is discharged, the battery will be discharged for 12 hours in full state; if discharged by 4A (An Pei), the discharge will be sustained for 3 hours. In addition this parameter for the charging current and provides an important reference value, if the rate of charge according to the 0.1C principle, the charging current should be selected 0.1 times the capacity value of the charging current value =12 x 0.1 =1.2A.
- Q:What is the difference between non - zero start and zero start of electric vehicle?
- [] is zero start the electric car when the ride started direct start, does not need external forces to make the wheels move up, then slowly start, there is now the electric car basically no nonzero start.
- Q:My small room and the distance is about 70 ~ 80 meters, my electric car is ordinary kind of Tianjin sunshine, 4 batteries, 48V, now want to take a little real power to the electric vehicle charging, do not know how many flat cable. Thank you, the power house usually lighting and charging, I saw a 1.5 flat on the Internet, 2 core cable, but the copper alloy do not know can not be used, please, professional advice.
- This kind of wire itself is not able to withstand such weight and tension.From the top down, recharge the first floor or basement electric bike,Can only be extended low voltage wires,The charging current is generally 2 AMPERES circuit strength,For extended wire total resistance,There are certain restrictions,Especially for lead-acid batteries,
- Q:Is an electric bicycle a home appliance?
- Household appliances have been published for nearly a hundred years, and the United States is considered the birthplace of home appliances. The range of household appliances, varies from country to country, household appliances classification has not yet formed a unified world, some countries will be classified as a type of lighting appliances household appliances, electrical appliances will be included in the audio-visual entertainment, and entertainment apparatus also includes electric electronic toys.
