Recently, the highly anticipated xEV Battery Forum has come to a successful conclusion. As an important participant in the field of battery management system (BMS) sensing, Huns made a stunning appearance with its core technology and innovative products. Not only did it successfully complete the exchange mission of this forum, but it also deeply shared innovative technologies through keynote speeches and communicated with industry partners, injecting innovative momentum into the field of new energy vehicle batteries and winning widespread attention from the audience.
In the core speech segment of the forum, Wang Bowen, Global Product Director of Huns, took the stage to share the theme of "Reshaping the Value Curve: Innovative Solution for the New Generation 0.2% High Precision Hall Current Sensor", deeply analyzing how Huns reshapes the industry's value (performance/price) curve through breakthrough technological innovation, and revealing the principles behind the excellent performance of Huns DHips+high-precision series.
The speech clearly pointed out that as the "heart" of new energy vehicles, the accuracy of the management system of the battery directly determines the vehicle's range, battery life, and operational safety. As the "nerve endings" of BMS, current sensors are the core carrier for achieving accurate monitoring of battery status. Traditional Hall current sensors often suffer from pain points such as insufficient accuracy and large zero point errors, making it difficult to adapt to the stringent requirements of the new generation of new energy vehicles for BMS, especially for lithium iron phosphate battery systems with weak voltage fluctuations but increasing market share, which require higher accuracy in current detection.
In response to the pain points in this industry, Huns has released a new generation of Hall current sensors that have improved accuracy to a super high level of 0.2%, completely solving the biggest drawback of open-loop Hall sensors and creating a sensor hexagonal warrior with almost no shortcomings. This breakthrough can not only assist customers in more accurate SOC and SOH estimation, extend battery cycle life, and improve vehicle range, but also help customers simplify system development work and reduce system costs.
In the speech, the details of technological innovation were further dissected: by coupling multiple compensation algorithms, the product achieved full range high-precision measurement and excellent magnetic field immunity, which can easily cope with the increasingly complex electromagnetic environment inside the battery pack. It also performs well in high and low temperature environments, perfectly matching the extreme working conditions of new energy vehicles.
