The Battery Management System (BMS) is the core intelligent control unit of lithium battery packs, which enables battery status monitoring, intelligent charging and discharging, cell balancing and multiple safety protection functions, ensuring the safe, efficient and stable operation of lithium batteries.
It features the following advantages:

(1) Collects core parameters of battery operation in an all-round manner to provide scientific data support for battery control.
(2) Adopts a dual protection design of hardware and software with rapid response to multiple faults.
(3) Dynamically matches charging and discharging strategies to adapt to power requirements under different working conditions.
(4) Optimizes the energy distribution of battery cells with professional balancing technology, effectively slowing down capacity fading.

Relays serve as the core switching and safety isolation components in the high-voltage circuits of lithium batteries, and act as the key control unit connecting battery packs with external charging and discharging circuits. Their core functions and advantages are as follows:
(1) On-off control of high-voltage circuits: Acting as the main positive/main negative/pre-charging switch to execute the start and stop commands of charging and discharging circuits;
Pre-charging current-limiting protection: Cooperating with resistors to suppress the inrush current during power-on, so as to protect core components such as circuit capacitors and power devices.
(2) Ultra-fast fault isolation: Receiving instructions from the BMS to disconnect abnormal circuits in milliseconds, isolating batteries from external equipment and eliminating potential safety hazards.
(3) Real-time status feedback: Transmitting on-off status to the BMS through auxiliary contacts to realize online monitoring of working status and fault early warning.
(4) Stable operation under extreme working conditions: Resistant to vibration and impact, maintaining stable circuit closure under harsh working conditions to avoid poor contact and instantaneous power failure.

A core passive component for high-precision current detection in lithium battery systems, the shunt is engineered for high-voltage and high-current conditions.Core Functions & Advantages：
(1) High-precision current detection: Low-resistance alloy base material ensures accurate capture of current changes under all charging/discharging conditions, with high precision and excellent linearity, delivering reliable current data for BMS.
(2) High-voltage & high-current adaptation: Strong current-carrying capacity for long-term stable bearing of rated current, perfectly suited for high-power, high-voltage and high-current scenarios like power batteries and energy storage batteries.
(3) Instant response with no delay: Real-time current signal sensing without lag, accurately capturing transient peak current to provide rapid data support for BMS fault protection.
