Drive Electric with Confidence – We've Got You Covered

The electric vehicle (EV) market seems to be ballooning, with drivers becoming more conscious of their vehicles' environmental impact. If you're planning to follow this surge of EV adoption (or have already done so), you must have some basic know-how of how electrical systems in these vehicles work.


Typically, an electrical system comprises a battery, an electric motor, and a power controller. Other components may include an electronic control unit (ECU), an alternator, a voltage regulator, an ignition system, fuses, wiring, and sensors.


The upkeep of these components is super important. At Eliot Park Auto Service, we use only the best tools and tested techniques to diagnose issues with electrical systems and resolve them promptly.

How Does an Electrical Vehicle Work?


The electrical systems in EVs have a specific working mechanism. Here's a brief overview:


  • When the vehicle's brake pedal is pressed, the controller takes electrical energy from the battery pack and inverter.
  • The inverter then changes the direct current (DC) into an alternating current (AC). Based on the pressure you've put on the pedal, it sends electrical energy to the vehicle's motor.
  • The electrical motor then transforms the electrical energy into mechanical energy. In simple words, it rotates.
  • As the motor rotates, so does the transmission, which transfers the power to the wheels.
  • Once you release your foot off the pedal, the controller regulates the motor and gradually stops it.


In case any of these components malfunctions, the vehicle can shut down. If that happens, you can count on Eliot Park Auto Service's expert diagnostics to bring it back to life. 


Components of Vehicle Electrical Systems


The essential components of electrical systems are as follows.


Battery and Charging System


Since the battery is the powerhouse of an electrical system, it supports many electrical components. It also helps start the engine.


Once the vehicle starts running, the voltage regulator and alternator take over to keep the battery charged. They also maintain optimal voltage levels. If this apparatus does not work correctly, the battery may die.


Starter


The starter draws current from the battery and sets the engine in motion. Then, the power distribution system ensures components, like the sensors and control modules, get sufficient electricity.


Electrical faults can occur if there's a voltage drop or poor grounding. Eliot Park Auto Service's technicians can fix these issues to improve the engine's performance.


Circuits


A network of circuits manages the power flow in an electrical system. If the circuit is faulty, electrical problems can follow, including non-functioning accessories and flickering lights.


Eliot Park Auto Service can perform circuit testing to identify these issues before they become severe. Our technicians also inspect other automotive electronics like control units to ensure everything is in order.


Power Inverter


The inverter converts the direct current from the battery into an alternating current to power electrical devices. This process is necessary because hybrid and electric vehicles run on AC and DC currents.


When the inverter fails, it can cause problems with the charging system and other electrical components. Eliot Park Auto Service has the expertise to diagnose and repair these issues efficiently.


Controller


As an electric system regulator, the controller oversees and manages voltage levels and monitors battery charging and discharging processes.


A malfunctioning controller leads to battery drain or overcharging. Our technicians at Eliot Park Auto Service can repair or replace the controller.


Thermal System


All electrical systems have a thermal management system to regulate the temperature. This prevents overheating and damage to electrical components.


The thermal system needs regular inspection and maintenance, which Eliot Park Auto Service can provide. We look for issues like coolant leaks and faulty fans and resolve them promptly.
