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. Controller: low cost, incomplete function, excessive discharge current, no overload, undervoltage, current limiting protection, resulting…

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 is a breakdown on the dial board Treatment: replacement of circuit board Abnormal motor operation…

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 battery Treatment: elimination of short circuit Cause 4: turn to turn short circuit Treatment: fat…

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 oxygen evolution voltage of the positive plate and the hydrogen evolution voltage of the negative…

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 place, check the electricity monthly and check fat tire electric bike; Do not add alarm.…

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 or basically adequate power, but from 100% there is a gap, every week or every…

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. However, improper handling will cause the battery to have an early loss of capacity, and…

Batteries need to be recharged before they are exhausted. Battery decay is accelerated when the battery is exhausted, so the correct routine is to keep the battery fully powered for a long period of time and fat tire electric bike is important parts. Get enough electricity before you leave. When someone drives a car, get…

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 difficult to overcome in technology, so that fat tire electric bike cannot reach the level…

At present, most electric bicycles use DC motor, and there are many kinds of DC motor controller. The core of the controller is pulse width modulator (PWM). A perfect controller, in addition to pulse width modulator, should also have battery under voltage protection, fat tire electric bike, brake power loss, power display and other functions.…

Electric bicycles have a lot of insignificant, but very important small parts - and one of them is the electric bicycle controller. Although the fat tire electric bike is not remarkable, but your electric bicycle start, advance and retreat, stop can depend on it. So what causes an electric vehicle controller to fail? Power device…

What is an Electric Bicycle Controller? Electric bicycle controller is used to control the starting, running, moving, moving, speed, stop and other electronic components of the core controller of electric vehicles. It's like the brain of an electric car. It's an important part of an electric vehicle. At present, electric vehicles mainly include electric bicycles,…

For electric bicycles, in addition to batteries, motors, and chargers, it is also one of the important core components of the electric bicycle. The charger is mainly composed of rectifier filter, high voltage switch, fat tire electric bike, constant voltage and electric control. The purpose of the rectifier filter circuit is to convert the AC…

In this case, it should be checked whether the voltage components are in bad or damaged contact. If everything is normal, then the charger should be replaced to exclude the fault. It has a lot of heat, and it's accompanied by an unusual noise that doesn't charge. The fault is caused by the output stage…

First of all, in order to extend the service life of your electric vehicle, it is recommended that you have the best help when the Chinese electric bike starts, and then use electric riding; Secondly, in the course of riding, if there is a steep slope or headwind, the first two are to avoid the…

In the past, there has been no way to prevent the sulfation of the battery, nor any way to prevent sulphuric acid from covering the lead plate. But today, the emergence of automatic sweep resonance and synchronous interference suppression pulse technology can completely solve the formation of sulfuric acid compounds and prolong the battery of…

The system is specially used to eliminate the problems and faults caused by the salinization of sulfide crystals on the electrode plate of lead-acid batteries. It can continuously remove the crystalline sulfides on the electrode plate of the Chinese electric bike battery, and can effectively prevent the new crystalline sulfides. It improves the working performance…

Lithium battery is a kind of battery which is composed of lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. The earliest lithium batteries of Chinese electric bike came from the great inventor Edison, using the following reaction: mno2=limno2, which is redox, discharge. Because of the active chemical characteristics of…
