This time, we will share the solution to battery and dynamo problems on electric bikes. Apart from that, you may also need to check out the popular online electric scooter Singapore store.
The electric bike feels not powered, battery quickly runs out.
slow speed, and slow and sometimes dashed speed.
When in the fast full charger full.
Battery problems are the most frequent problems in electric vehicles. Almost an average of some electric vehicle users experiences this problem.
The repair solution is to replace a damaged battery, ideally, all the batteries are replaced, but if you want to save money by replacing a damaged battery only. How to know which battery is damaged can be measured battery voltage using a multimeter. The measurement is good when the system is ON and is used to play the Dynamo without load.
Damaged battery prevention solutions are:
Do not overcharge / charger is too long.
Do not too often accelerate suddenly.
Avoid heavy loads / uphill terrain.
The problem on the dynamo
The problem with the BLDC motor is the second problem. Although the frequency of damage is less than battery damage, but sometimes a lot of users who stuck their electric bikes just because of the problem on the motor drive.
The signs of dynamo damage are:
When the motor turns limp on.
The motor will rotate when assisted in the prefix.
The sound of the motor buzzed roughly and did not have the energy.
Motor rotation slowly and is broken.
The motor does not live when in gas, but when assisted turn by hand it feels there is induction against (this is due to a combination of hall pattern of sensor and 3 phase which do not fit, stay random again combination is done) but this usually happened in the modified electric vehicle.
BLDC motor spins a moment and dies sometimes unstable rounds (this is usually because BLDC motors are too often unloaded and installation is less precise).
Repair solution: BLDC motor drive damage to electric vehicles generally occurs due to two kinds of problems: hall sensor problem and 3 phase motor problem. But in general in electric bikes more frequent damage due to hall sensors. 3 phase damage, damage to mounting cradle, axle damage is more common due to inadequate modification.
