The temperature of the protection board increases due to continuous overcurrent due to large currents, and the aging is accelerated; the overcurrent performance is unstable, and the protection is frequently triggered by mistake. With the new high-current S series software protection board launched by Daly, these problems can be easily solved.
Daly S series software protection board is suitable for ternary lithium, lithium iron phosphate, and lithium titanate battery packs with 3 to 24 cells. The standard discharge current is 300A/400A/500A.
Professionally handle large currents
Many traditional protection boards often suffer from overcurrent instability and temperature rise when excessive current flows. This will not only reduce the service life of the protection board, but also pose safety risks. Daly has specially created a battery management system for high current usage scenarios - Daly S series software protection board.
Daly S series software protection board uses a patented thick copper high-current board to provide higher current carrying capacity, ensuring that the protection board can work stably when dealing with large currents and avoiding damage to the protection board caused by overcurrent.
There are also advanced thermal design processes and multiple heat dissipation designs to ensure the stable operation of the protection board. The multi-channel fan heat dissipation design is matched with an aluminum alloy wave-shaped heat sink, which greatly improves the air circulation efficiency and heat dissipation area.
Multiple guarantees enable the protection board to maintain a stable working state when dealing with large currents, with low temperature rise and stable overcurrent, extending the service life of the protection board and reducing the failure rate.
Comprehensive intelligent expansion
In terms of software intelligence, the S series software protection board is equipped with CAN, RS485 and dual UART communications and multiple expansion sockets. Multiple protection values such as overcharge, over-discharge, over-current, temperature, and balance can be freely adjusted on the mobile phone APP or computer host computer, making it easy to view, read, and set protection parameters.
In addition, the S series software protection board can also be linked with Daly Cloud to realize remote batch management of lithium batteries, save lithium battery data in the cloud, and remotely upgrade the protection board.
There are also more intelligent expansion ports that support multi-channel NTC, WIFI modules, buzzers, heating modules and other expansion applications to achieve true intelligence.
Multiple protections for greater peace of mind
When two or more battery packs are connected in parallel, if their voltage or current are unbalanced, a large current surge may occur. The S series software protection board integrates a parallel protection function, which can effectively prevent battery packs from being connected in parallel. Achieve safe capacity expansion despite being impacted by large current.
In addition, in order to effectively avoid false triggering protection caused by large current at startup, the S-type software protection board adds a precharge function, which can better adapt to capacitive loads and improve the stability and reliability of the equipment.
Choosing a 5KW bidirectional high-quality TVS can clamp the instantaneous high voltage to a safe level in a very short time, effectively protecting the precision components in the BMS from large current impacts.
The S series software protection board has customized advanced thermal design technology, which can monitor the temperature changes of the battery in real time and provide temperature warning in advance, effectively preventing hidden dangers such as battery fire.
Small size, big energy
The size of Daly S series software protection board is only 183*108*26mm. Compared with traditional protection boards with the same current, the size and weight are greatly reduced. Whether it is a large or small device, it can be easily installed and costs during transportation and storage will be reduced accordingly.
Innovation continues
Daly always insists on tracing the user experience and pain points of usage scenarios and continuously improves product performance. The software and hardware of the S series software protection board have been comprehensively upgraded and optimized, representing Daly's latest technology and innovation achievements in the field of lithium battery management systems.
Daly continues to work hard in the field of innovative technology, innovate technologies and develop products, and will bring a better lithium battery management experience to thousands of lithium battery users in the future.
