How to pick electric cars
According to the battery type is divided into lead-acid, nickel hydrogen, lithium batteries. A battery is a set of voltage and capacitySuch as, some vehicles with 24 volt 8 ah, like Yilaida 125 with Haibao 48 volt 14 ah, theyBetween capacity, power, distance, price difference 2 - 3 times. Controller intrinsic quality and price,Performance is also very different.
The key problems that should be paid attention to when choosing electric bicycles are as follows:1, select configuration: motors, batteries, controllers, chargers are the four major electric vehiclesCore components. For example, there are three kinds of motors: high speed motors, low speed brushless motors and low speed brush motorsMachine. Battery according to voltage points are 24V, 36V, 48V; according to capacity points are 8Ah, 12Ah, 14Ah and so onVaried。
Look at the use: high speed motor, high efficiency, power, climbing ability, suitable for comparisonLong distance running requires a certain climbing ability and riding heavy weight of the user; no brushLow speed motor adopts electronic commutator to solve the commutation problem of current, so the controller is easy to burn,The reliability of the whole system is transferred from the motor to the controller, and the low speed motor with the brush is of low efficiency,Large power consumption, mileage is shorter, the motor is only applicable to the flat road, the rider is light,Start climbing for consumers with the right help. High speed motors are nearly twice as expensive as low speed motors.
3, than service: dealer service commitment is not the same, whether can promise still very muchIt is difficult to say, and some take vague commitments, such as the whole car warranty for one year, repair said, wearing parts are not inWarranty scope, users feel fooled, should choose large-scale, reputable businesses to buy. LuqingThe company launched the car for twenty months without spending a penny, the whole vehicle free maintenance for life, every yearTwo free seasonal maintenance, booking service, the city's ten store chain card and a series of servicesAllow consumers to eat a reassurance.
