FAQ

Those who are looking for an answer to the question «Why is my electric car not starting?» often ask the following questions:

👉 Electric motor starting capacitors?

Electric motors that use start/run capacitors may be PSC (permanent split capacitor) and CSR / CSCR (capacitor start, capacitor run) designs. Unlike a PSC motor, a CSR/CSCR motor must also have a starting relay that will cut the start capacitor out of the electrical circuit once the motor has gotten up to run speed.

👉 Do electric motor starting capacitor?

Starting Capacitor and Switch A capacitor, connected to a separate coil on the motor, creates an alternating electric current ahead of the main phase by 90 degrees. This happens because the current through a capacitor leads the voltage by 90 degrees.

👉 Electric motor chatter when starting?

Coils have a voltage rating and tolerance. For example, a 15% tolerance is common. If a 120v coil is only getting 100v then the contacts may chatter. Set your voltage tester to AC voltage and put your leads on the hot and neutral terminals of the coil. This is because metering at the coil will give the most accurate reading.

As you know, the battery is in charge of powering all electrical accessories in your car if the alternator is not running.

Corrosion can develop inside of the insulation and cause too much resistance for proper current. The "click, click" is a classic sign of not enough power getting to the starter but the fact that it started after you shook your terminals means there is enough power in the battery it's just not getting to the starter.

You may need to jump-start an electric car if its batteries have been completely drained, or if the 12-volt battery is on its way out. The lithium-ion batteries may not be able to be recharged unless the vehicle is jump-started via the 12-volt system, allowing the electronics to operate first.
