By measuring the supply voltage or signal voltage of the connecting parts or leads of the controller, we can analyze and determine the fault of the controller. Referring to the main phase check measurement diagram of the brushless controller, a

The most important thing to maintain for a foldable electric bike is a battery. It is best to discharge and charge the battery at regular intervals. Usually two or three weeks. This can activate the capacity of the battery, so

Recently, some data show that the sales data of electric bicycles in the United States ushered in explosive growth, with an increase of more than 400. Sales as high as 26.3 w, of which 80% of the sales from Chinese

First of all, the maintenance of bicycles after rain do not use sewing machine oil. Sewing machine oil is a kind of thin lubricating oil. If it is used on bicycle, it will dilute the original butter in the car

In 90s the manufacturing process in Shanghai represented the highest level in the country, so made in Shanghai represented quality. The electric car industry still has this phenomenon, many folding electric bike are under the banner of Shanghai. The Shanghai

How fast is an electric bike? The dashboard of an electric bike is generally virtual and the speed has been adjusted. At present, the speed of the universal motor is at 32kmg / h, 48v / 350wN, and the special

After charging the lamp, the test instrument is used to detect the data. The voltage of the new battery is not higher than 59.5, and the battery of folding electric bike about half a year is not higher than 58.8,

Now the lead acid battery is generally used, the regular detection of lead acid battery must detect the actual capacity, generally 0.5 c as the standard discharge rate of 2 hours capacity value, if not up to the manufacturer’s prescribed

In rainy days, it is best not to ride electric vehicles. If there are no other means of moving, you should try not to let them rain. The simplest way is to cover up the controller. In addition, when the

Set the multimeter in 20 V DC) gear, first measure the high and low potential of the gate handle output signal. If the signal of the knob has a potential change of more than 4 v when kneading the knob,

If you don’t have the most basic life span of a year, here are a few reasons: Charger: two-stage charger circuit is simple, cheap, and easy to cause voltage instability. Overshoot, floating, unprotected, directly affect fat tire electric bike life.

Reason 1: there is no voltage between the positive and negative leads of the dial because the wire or connector is broken. Processing method: reconnect Cause 2: fat tire electric bike damage Treatment: reshuffling the luminous tube Reason 3: there

Reason 1: deviation of fixed magnetic steel Treatment: rebonding The gap between 2: carbon brushes is not uniform Treatment method: correction of carbon brush gap Reason 3: there is a short circuit between the positive and negative electrodes of the

In order to meet the short-term and high capacity charge of electric bicycle battery, the constant voltage value has to be increased to 2.47 V or 2.49 v in the three-stage constant voltage current limiting charging. In this way, the

Pay attention to pedal booster start. When electric bicycle starts, use pedal booster to avoid excessive discharge current and damage battery. If the electric bicycle does not use for a long time, pay attention to the battery charge and then

Charge in time after using up. Do not allow electric vehicle battery to be placed for a long time without electricity, otherwise the battery plate will be sulphate. Recharge once a week. The green light, said battery can be used

Battery grid Battery grid is an important component to determine the sealing performance of the cell. Now the battery grid produced by electric bicycle manufacturer mainly adopts lead-calcium-tin alloy. This alloy is one of the core technologies of sealed batteries.

At present, the batteries used on electric bicycle include sealed lead acid battery, lithium ion battery, nickel hydrogen battery, lead cloth battery and so on. However, the technology of lithium ion battery, nickel hydrogen battery and lead cloth battery are
