EVs & Dash Cams Myth #1

I have always been intrigued by the growing popularity of electric vehicles (EVs) and the advancements in technology that accompany them. As I delved deeper into the world of EVs, I came across numerous misconceptions and myths that surround this transformative mode of transportation. In this blog post, I will address the first myth: the belief that installing a dash cam in an EV is unnecessary. Let me share my own experiences and shed some light on the truth behind this misconception.

EVs & Dash Cams Myth #1: Wiring a dash cam to an EV battery won’t drain it

As an EV owner, one of the key concerns is ensuring the battery life is optimized. This concern often extends to the installation of dash cams. A prevalent myth regarding dash cams and EVs is that wiring the dash cam directly to the EV battery will not drain its power. In this article, I will debunk this myth and shed light on the real impact of dash cams on EV battery life.

  1. Energy efficiency of dash cams:
    Contrary to popular belief, dash cams are not energy-efficient devices. These compact cameras require power to function, and while their power consumption may vary, it is important to understand their impact on an EV battery. Dash cams constantly record footage, which requires a continuous power source.

  2. Built-in voltage and timer cut-offs:
    Many dash cams come with built-in voltage and timer cut-offs. These features are designed to protect the vehicle’s battery from draining excessively. When the battery voltage drops below a certain level, the dash cam automatically stops drawing power to preserve the battery’s charge.

  3. Premium dash cams and power management:
    Premium dash cam brands like Linkware or Blackview offer advanced power management options. These dash cams allow micromanagement of power consumption, allowing EV owners to customize settings and optimize the camera’s use without significantly impacting the battery life.

  4. Impact on the EV’s large battery:
    It is important to note that dash cams do not significantly impact the large battery of an EV. EVs are equipped with high-capacity batteries that are designed to power multiple systems, including infotainment, climate control, and other accessories. The power drawn by a dash cam is minimal compared to the overall capacity of an EV battery.

  5. Automatic power-off feature:
    Furthermore, most dash cams have an automatic power-off feature. When the EV’s battery reaches a certain low level, the dash cam automatically stops drawing power. This feature ensures that the dash cam does not drain the battery beyond a safe threshold.

In conclusion, the myth that wiring a dash cam directly to an EV battery won’t drain it is not accurate. While it is true that dash cams do require power, their impact on an EV battery is minimal. With built-in cut-offs, power management options, and automatic power-off features, dash cams can be safely installed in EVs without worrying about significant battery depletion.


  1. Will installing a dash cam void my EV’s warranty?
    Installing a dash cam should not void your EV’s warranty. However, it is always recommended to consult your vehicle manufacturer or dealership before making any modifications.

  2. Can I charge my dash cam with my EV’s charging port?
    Most dash cams are powered by the vehicle’s battery and are not designed to be charged through the charging port. They usually draw power directly from the vehicle’s electrical system.

  3. Do dash cams drain the EV battery while the car is parked?
    Dash cams with built-in cut-offs and power management systems are designed to minimize power consumption while the vehicle is parked. However, it is advisable to configure the dash cam’s settings to reduce power consumption during extended parking periods.

  4. Will a dash cam affect the range of my EV?
    The impact of a dash cam on the range of an EV is negligible. The power consumed by a dash cam is relatively low compared to the overall energy capacity of an EV’s battery.

  5. Can I install a dash cam myself or should I seek professional help?
    Installation difficulty may vary depending on the vehicle model and the dash cam itself. While some dash cams can be easily installed by following the manufacturer’s instructions, others may require professional assistance. It is recommended to refer to the product manual or consult a professional if you are unsure about the installation process.
