Are your electric cars, storage cabinets, electric tools safe?
Today, with new energy waves sweeping the globe, lithium batteries have become a core power source for electric cars, domestic storage, electric tools and even electronics. However, the safety of the batteries has never disappeared — overloading, overlaying, short circuits, uncontrolled temperatures. .. Neglect at every link can have irreversible consequences.
Behind all this is a key player who is silently guarding the safe boundaries of each battery: the Battery Management System (BMS) and its vital power component, MOSFET.
Why can't BMS have high-performance MOSFET?
PART 1
BMS is the "brain" of the battery system, which monitors voltage, current and temperature in real time and ensures that batteries operate in the safe zone through sophisticated charge control. MOSFET, which is the "muscle" of BMS to implement these control instructions, directly carries out electrical current breakage, determining the speed of system response, the size of loss and the accuracy of protection.
Mischosen MOSFET, the consequences of which are unimaginable: excessive internal resistance leads to severe heat and accelerations of battery ageing; poor switch properties are slow to protect against dangerous currents in milliseconds. In particular, lithium batteries are extremely sensitive to temperature and thermal performance of MOSFET is directly related to the life and safety of the battery package as a whole.

MOSFET-wide solution for BMS depth optimization
PART 2
A complete MOSFET product matrix covering 20-250 V, 12-500 A was launched for the core pain points of the BMS application for a number of years to fully meet the demand for diversification from small-scale consumer batteries to large-scale storage systems.
The entire product was designed with a unique device structure, combined with an advanced containment process, to achieve a breakthrough on two core indicators:
• Extremely low Rds (on): a significant reduction in conductivity resistance, a reduction in thermal dispersion during charge-taking, and the maintenance of low-temperature and stable operation of battery packages under high current conditions;
• High-EAS (single-pulse avalanche energy): the resistance of the device to an abnormal wave surge has increased significantly, significantly increasing the safety of the battery system.
A summary of the recommendations for the Lithium Lithium Protection (BSS) type:

Whether it is a small BMS for two-wheel powered vehicles or a large battery management system for commercial and industrial energy, Jen-Hyun can provide a precise matching package selection and technical support programme.
Heat design driver selection, ingenuity engineer reduced efficiency
The team suggested that the MOSFET selection would need to be combined with an integrated assessment of the system's thermal design: the determination of a reasonable number of combinations by thermal simulation and the target Rds (on) would find the best balance between cost and performance. It provides complete reference options and thermal performance data support, helps clients to compress the design cycle and accelerate the marketing of products.
Concluding remarks
The battery is safe, and each MOSFET is a key defence to life and property. With the advantage of an autonomously developed, stringently controlled, home-grown plant, the Ingenuity Electronics provides BMS design engineers with a reliable power plant building block.
