How do you adjust the speed of the electric vehicle two
If a friend has a better, more abnormal change, welcome to discuss the opinions, I have limited knowledge, only know so much, now dedicated to all people, also want to change a company's *, participate in electric car modification, will carry forward (most dealers do not love to engage in speed, is very depressed). 4: do not hand off, want to improve rapidly the fans, only need a section of the original battery with the specifications of the battery in series with the 60V voltage, the motor is generally more suitable for overclocking, brushless motor (motor internal loss, serious pollution, no law to ensure that the service life of the motor output series) note the position is not the end of the battery box, it will only make your table lamp and burned and refused to work on the general controller, controller input will have 3 lines, 2 positive line a single negative line in positive line generally have 1 thick and thin, thick is controlled by the input line controller of power transistor and direct output to the motor, the fine root is the switch line (general 48V controller, voltage switch line input undervoltage protection needs to be higher than that below the controller to start voltage protection, controller) So the position only in tandem switch line, the input voltage switch line to keep the original 48V, while the voltage of power transistor is increased to 60V, it can make the theory to improve the vehicle performance (including rapid speed and 25%), but instead we must do before the controller cooling work, can use computer CPU radiator film, a fan and a thermally conductive adhesive, fixed many methods, here is not to say, the downside is the summer reduced mileage, because of the increase of 25% of the voltage, the heating power of the electric motor will greatly increase the risk of Holzer is beyond the limit temperature of the summer, continuous high-speed riding should not exceed 15KM.
3: life group, head of modified method, because the structure of electric motor characteristic, resulting in electric cars than motorcycles, speed up more space for gas cars, if you hand to want to enjoy the car owners in the city Biao style try, as the method with second methods, but much more increase some expenses, otherwise buy a matching motor and a rear wheel and a controller, with separate power supply, will be directly installed on a front wheel (motor wheel and the rear wheel is the same), computer in dual core, full torque is doubled, the key is the weight of the motor engine is generally much less (estimated Motorola and gas may not change) so the weight of the vehicle is limited to a battery in addition, acceleration effect is only really see people can feel (light faster than 2 rushed at present in Shanghai Only seen 1, want to catch up to ask, but can not catch up, ha ha) for haste, dare not talk about. I really want to find that guy and try it on. Don't know if anyone saw this car forum (yellow body, stick out of order, very eye-catching, fancy can not be spent, but the front wheel structure) seen most of the electric vehicle, the suspension only inserted a chance to change the motor must is the kind of flat, now some more than 800W the motor is too thick, there is not installed on the front wheel, the proposed purchase of brake motor with double power conversion, speed is important, or to ensure the safety of!
Can also buy an electric vehicle controller, in the circuit in parallel while the motor power supply, but the battery is not parallel, individually to a power supply controller, so as to maintain battery life and improve the acceleration theory, this modification increases torque to contact and large than the simple, but the output power is more difficult control, generally reducing power in parallel, I have tested 500 500W motor, dual controller, although the start is very fierce, but obviously feel hard over the head, the output power is too large, has exceeded the motor limit, a great noise, there is the problem of PYLL, personal recommendations, 500W motor controller with two limiting 15A it was enough for 48V500W 30A, current motor, input power has reached the limit 1500W, try not to exceed 1600W.
