12V Jump Starter / Power Packs
Product Description:

The 12V Jump Starter / Power Pack is a vital roadside rescue tool designed specifically to jump-start or boost the low-voltage auxiliary system on electric and hybrid vehicles. Although EVs rely on massive high-voltage traction batteries (400V–800V) to drive the wheels, the vehicle's onboard computers, safety contactors, keyless entry systems, electric parking brakes, and shift actuators are powered entirely by a standard 12V auxiliary battery.

When the 12V battery drains completely, the main high-voltage contactors cannot close, rendering the EV completely unresponsive and locking the drivetrain in park. This portable, high-current jump starter quickly energizes the 12V electrical system, allowing the driver or recovery technician to disengage the electronic parking brake, shift the vehicle into neutral for flatbed loading, or engage the high-voltage system to initiate charging.

Key Technical Specifications:

Peak Output Current: Delivering high peak boost currents (typically 1,000A to 4,000A) for immediate low-voltage system activation.

Battery Chemistry: High-density Lithium-Ion / LiFePO4 chemistry providing maximum energy output in a lightweight, ultra-portable form factor.

Smart Clamp Protection: Equipped with heavy-duty smart jumper clamps featuring reverse-polarity, short-circuit, over-voltage, and spark-proof safety protection.

Integrated DC Power & USB Outputs: Includes 12V DC auxiliary ports and fast-charging USB/USB-C ports to power external diagnostic tools and mobile devices.

Built-In LED Diagnostic Screen: Digital LED display indicating real-time output voltage, internal power level, and clamp connection status.

Primary Applications in EV Handling:

Brake & Neutral Release: Powers up the 12V auxiliary bus to disengage electronic parking brakes and shift locked EV transmissions into neutral.

High-Voltage System Activation: Provides the required initial 12V power signal to close the main battery contactors and boot up the main vehicle control units (VCUs).

Emergency Vehicle Access: Operates keyless entry systems, power windows, and trunk/frunk locks on vehicles with completely dead 12V batteries.

Roadside Service & Recovery: Serves as a compact, self-contained power supply for breakdown operators handling stranded EVs.
