From Battery Testing to Intelligent SuperCap Starting Support: How leagend's Technology Evolved
Share
Traditional jump starters are primarily designed for emergencies. When a vehicle's battery can no longer start the engine, a portable jump starter provides additional power to get the vehicle running.
The leagend SuperCapacitor Jump Starter Series takes a fundamentally different approach.
Instead of waiting for a starting failure, the system is permanently installed alongside the vehicle's original battery, becoming an integrated part of the starting system. It automatically participates in every engine start, sharing the high-current starting load with the original battery. Combining battery-free supercapacitor technology with intelligent monitoring and energy management, it introduces a different approach to everyday vehicle starting support.
But how did leagend develop a product that goes beyond the conventional role of a jump starter?
The answer lies in more than two decades of technological development.
Since its establishment in 2005, leagend has continuously expanded its expertise in battery technologies and automotive electronics. Its capabilities have evolved from accurately understanding battery condition to monitoring performance over time, actively managing battery energy, and ultimately supporting the vehicle's everyday starting process.
This evolution is not simply about introducing more product categories. It reflects how leagend has progressively expanded its ability to understand, manage, and support vehicle batteries through increasingly sophisticated technologies.
Precision Battery Testing: Understanding Battery Condition
The foundation of effective battery management begins with understanding battery performance.
For automotive professionals, voltage alone cannot provide a complete picture of battery condition. Parameters such as cold cranking amps (CCA), internal resistance, state of health (SoH), and state of charge (SoC) offer essential information about battery performance and starting capability.
Precision battery diagnostics has long been one of leagend's core technical strengths.
Through its professional leagend Battery Tester products, the company has developed capabilities in accurate measurement, intelligent analysis, and vehicle electrical system diagnostics.
Products such as leagend BA4000 demonstrate this expertise through 6V, 12V, and 24V battery testing, together with cranking and charging system diagnostics. Meanwhile, leagend BT2000PRO combines professional CCA testing with continuous battery monitoring, app connectivity, and a wireless display.
Beyond measurement accuracy, leagend has also placed considerable emphasis on energy efficiency. With an average operating current of only 1.5mA, leagend BT2000PRO reflects an exceptional commitment to energy efficiency and minimizing power consumption from the vehicle battery.
These capabilities demonstrate leagend's expertise not only in evaluating battery performance but also in developing energy-efficient electronics suitable for long-term vehicle connection.
Yet understanding battery condition at a single moment is only part of the challenge. Battery performance continues to change throughout its service life, creating the need for ongoing monitoring.
Continuous Monitoring: Understanding Battery Performance Over Time
While battery testing provides an assessment at a particular moment, continuous monitoring reveals how battery condition changes over time.
This requires more than accurate measurement. Devices must remain connected for extended periods, collect meaningful data, and operate with exceptionally low energy consumption.
Through its leagend Battery Monitor products, the company has extended its technical capabilities into continuous battery monitoring, ultra-low-power operation, and connected data management.
The leagend BM6 demonstrates this approach, combining Bluetooth monitoring with an average operating current of just 0.94mA and voltage measurement accuracy of ±0.03V. Users can review battery status and historical information while minimizing the monitoring device's impact on battery energy consumption.
The leagend BMS100 further extends these capabilities through 4G connectivity, enabling remote battery monitoring, historical data access, and status alerts.
Beyond individual devices, leagend SOLUTIONS demonstrates the company's capabilities in integrated battery management, combining monitoring hardware, data communication, cloud platforms, and analytical functions for professional applications.
This development represents an important expansion in technical expertise: from measuring battery parameters to continuously observing battery performance and managing information across connected systems.
Accurate sensing, energy-efficient design, continuous data collection, and intelligent monitoring have become complementary capabilities within leagend's technology portfolio.
With a deeper understanding of battery conditions and their changes over time, another area of battery management comes into focus: how electrical energy can be actively supplied and controlled.
Intelligent Charging: Expanding into Battery Energy Management
Understanding and monitoring battery condition provide valuable information. Intelligent charging extends battery management into the active control of energy replenishment and maintenance.
Through its leagend Battery Charger products, the company applies intelligent control technologies to battery charging, combining automated processes with battery maintenance functions.
Representative products include leagend BC501, leagend BC521, and leagend BC531, featuring eight-step intelligent charging, temperature compensation, and advanced charging management.
A notable feature is leagend's Smart Unattended Mode, which supports automatic charging and maintenance during appropriate long-term battery connection, reducing the need for repeated manual intervention.
The integration of testing and charging in leagend BC521, along with Wi-Fi connectivity in leagend BC531, further demonstrates how measurement, electronic control, and connected technologies can operate together.
Alongside these developments, leagend has expanded its automotive electronics expertise through OBD II diagnostics, precision battery measurement with leagend RT200, and infrared thermal imaging technologies.
Together, these technologies reflect growing capabilities in electronic measurement, sensing, power management, and intelligent control.
Battery charging and vehicle starting, however, involve different electrical requirements. Charging focuses on managing energy replenishment over time, while engine starting demands substantial current within seconds.
This distinction introduces another opportunity for technological innovation: combining relevant battery management and electronic control expertise with supercapacitor technology to support the vehicle during every engine start.
Intelligent SuperCap Starting Support: Bringing Technology into Everyday Starting
Every engine start places a significant short-duration current demand on the vehicle's original battery. Repeated starting loads, temperature variations, and operating conditions can influence battery performance and service life.
The leagend SuperCapacitor Jump Starter Series addresses this challenge by moving beyond emergency-only starting assistance.
Rather than simply providing backup power after a starting failure, the system integrates starting support into the vehicle's normal operation.
From Emergency Assistance to Integrated Starting Support
Designed for permanent installation, the leagend SuperCapacitor Jump Starter Series works alongside the original vehicle battery and automatically participates in every engine start, sharing the high-current starting load.
By reducing the instantaneous electrical burden on the original battery, the system helps reduce battery stress and supports longer battery service life.
Importantly, the system is not intended to replace the original battery or restore a failed battery. Instead, it works alongside the vehicle's existing electrical system, providing continuous availability for everyday starting support.
This represents a fundamental shift in product design: from responding to starting problems after they occur to actively supporting the battery during normal vehicle starting.
Integrating Monitoring, Intelligent Control, and Supercapacitor Technology
Achieving this functionality requires several technical capabilities to work together.
The leagend SuperCapacitor Jump Starter Series incorporates vehicle battery voltage monitoring and intelligent operating controls, supporting its ability to remain connected and respond to changing operating conditions.
Energy efficiency is particularly important for a permanently installed system.
When the original battery voltage falls below approximately 9V, the system enters a low-energy operating mode to minimize its own power consumption. Its vibration-sensing wake-up mechanism allows the system to detect vehicle movement, automatically waking and returning to the appropriate ready state.
At the heart of its starting support capability is battery-free supercapacitor technology.
Unlike conventional portable jump starters that rely on internal chemical batteries, supercapacitors can rapidly store and release high currents, delivering powerful starting support with an exceptionally long charge-discharge cycle life.
The series is designed to operate across a temperature range of -40°C to 80°C, supporting operation in demanding environments, including extremely cold regions.
Even when the vehicle's original battery voltage drops to just above 5V, the leagend SuperCapacitor Jump Starter Series can still draw energy from the battery to recharge its internal supercapacitors.
