The battery is usually used in series, that is, the positive pole of one battery is connected to the negative pole of the other battery, all the batteries are connected together, and the remaining positive and negative terminals are connected to the corresponding wiring of the electric bike, the motor of the electric car, The…

¡¡¡¡Power supply does not start: plug in power supply, large capacitance has 300 v voltage, unplug power supply again measure large capacitance 2 terminal or 300 v voltage does not drop. After discharging the capacitor, replace the starting resistor. Starting resistance in the power input part, resistance value 150 k, power 2 w. ¡¡¡¡The power…

Lead acid battery life is generally in the 360-time repeated charge, so it is best to use to 3/4 in charge, do not charge frequently; Hold the electricity once every half of the month. When the amount of electricity is found to drop obviously, you can try the depth of the point, use the electricity…

The purchase of best electric bike 2017, due to factory, transport, storage takes a certain amount of time, may cause battery power shortage, please charge before use. Check that the rated input voltage of the charge is consistent with the supply voltage.   The battery can be charged directly on the car, but it must…

It is a special bicycle with two wheels, which can ride by human, electric or electric auxiliary function. Charger, it is the battery to recharge the device, generally divided into two-stage and three-stage charging mode. Batteries, mainly lead-acid batteries, nickel-hydrogen batteries and lithium-ion batteries in some light folding electric vehicles began to use. Controller, which…

¡¡¡¡The dash board is the display electric bike parts, now the instrument in use is divided into led display and pointer display. ¡¡¡¡In the design of led instruments, it is very possible to concentrate some auxiliary functions (such as under voltage indication, caller ID, cruise etc.) on the display board, so we must understand the…

We mainly say the development history of electric bicycle, from the development track and historical opportunity of this industry, we look at the present situation and future of this industry, perhaps we will let go of the present uneasy heart. Sink in the industry and make progress.   The development from the Tsinghua University in…

According to the product classification of e-bike industry, can be divided into two categories, namely: four-wheel e-bike and two-wheel electric vehicle. Analyzing from the target market of e-bike, the target market of four-wheel e-bike is: railway station, warehouse, real estate clubhouse, tourist spot, hospital, post office, park, sports place, large-scale factory, large-scale shopping mall, and…

¡¡¡¡Handle and riser in the new 750 watt electric bike generally do not need to repair, but after the use of a longer time will appear rust, this time cannot be forced screw, should first use loose embroidery water treatment for a period of time, and then with iron hammer carefully knocked on the outside…

Looking back on the birth and development history of electric bicycle in China, it was born in 1985 and began to develop rapidly in 2003. After nearly five years of increasing speed, the industrial scale and production and sales volume have kept increasing by more than 50% every year. Especially in 2005 / 06, the…

The electric bicycle does not have three packets stipulation, the electric bicycle is not the national compulsory three packets scope, at present the electric bicycle three packets are all voluntarily undertaken by the manufacturer, the three packets range has the electric machine 5 years, the battery, the controller one year each. There are generally three…

In the actual use of electric bike, the charging standard is not uniform problem is very obvious.   After the whole line of the Beijing-Shanghai Expressway charging Station was opened, a working group was sent by some enterprises to conduct electric vehicle operation tests. As a result, this car can be recharged at this charging…

The motors in use on the market are generally brushed low speed, brushless high speed, and brushless low speed and so on. Brushless high speed is not commonly used. The difference between high speed and low speed mainly depends on whether or not gear decelerates. The purpose of gear reduction is to improve the speed…

United States charging station development plan: Two years double tenfold, the development speed is quite fast, if is merely quantity, also is not surprising. Chargpoint, for example, is not just a simple charging network, it can also provide a lot of cloud services to electric car owners, dealers and manufacturers.   For example, an motorized…

Motorized bikes charging stations are similar to car gas stations and are power-on equipment. Electric car charging station is a kind of high efficiency charger. A charging station that recharges electric bike, and older vehicles.   The installation of charging stations should meet the requirements of urban master planning and road network planning. Site selection…

¡¡¡¡The load current of the 250 watt electric bike motor mainly reflects the actual running efficiency of the motor. If the load current increases, but the actual torque is small, the motor efficiency is very low, it is necessary to check the magnetic energy product of the magnetic steel. In addition, the soldering firm inside…

Currently, it is generally the Energy Bureau and grid companies to do the planning. At present, the theory of charging station construction planning layout for e-bike application is not yet complete and mature.   The construction of charging stations in various places is still in the stage of fixed-point demonstration construction, which is not based…

Up to this date, the number of electric bicycle charging piles built in China has reached 26,000. But in terms of numbers, it's a lot, but according to a number of Chinese media surveys, the proportion of charging piles in use is very low.   In addition, the standard of DC charging interface and communication…
