Why Do Electric Vehicles Need a Jump Starter?
Electric vehicles (EVs) may need a jump starter primarily due to issues related to their 12-volt battery, which powers auxiliary systems, rather than the main high-voltage battery that drives the vehicle. If the 12-volt battery is drained, the vehicle’s electronic systems may fail to operate, necessitating the use of a jump starter.
According to the U.S. Department of Energy, EVs utilize a smaller 12-volt battery to power components such as lights, infotainment systems, and other electronics, similar to traditional gasoline vehicles. If this battery is depleted, the vehicle may not start, even if the main battery has sufficient charge. This can happen if the vehicle has been left in a state of inactivity for an extended period or if there are parasitic draws from devices that draw power when the vehicle is off, as highlighted by a report from the Electric Power Research Institute.
The underlying mechanism involves the relationship between the 12-volt battery and the vehicle’s electronic management systems. When the 12-volt battery is low, it fails to supply adequate power to critical systems that initiate the boot-up process of the car. This includes powering the vehicle’s computer system, which requires a minimum voltage to operate. If this voltage is not met, the vehicle will not start, regardless of the charge status of the main battery. Therefore, having a reliable jump starter for EVs becomes essential, particularly for those who may find themselves in situations where the 12-volt battery is compromised.
