Motor controllers for electric vehicles like the TIM600 in MR02EV typically have a large internal capacitor bank on their input with very low Equivalent Series Resistance(ESR). As such they require inrush protection when first powering up to prevent a large current spike which can damage components – most commonly, welding contactors shut or blowing fuses. In MR02EV I use a ZEVA Smart Precharger which is designed with a 2-stage soft start to limit inrush current via a resistive circuit that charges up the inverters internal capacitors before automatically closing the main contactor when the process is complete. www.zeava.com.au
