Intelligent battery sensor solution

The intelligent battery sensor solution has the features:high integration, low power consumption, high cost performance.It can also provide comprehensive technical support in time.
Solution Introduction

The Intelligent Battery Management System (IBS) is primarily used for common start-stop functions to help reduce CO2 emissions.

The IBS system continuously analyzes the state of charge of a 12V lead-acid battery. It will then tell the superior control unit (eg engine control system, body controller) whether there is enough energy in the battery to ensure that the motor can be automatically shut down (stopped) and started again. Thanks to the monitoring of battery current, voltage and temperature, the entire vehicle electrical system has achieved higher reliability.

Traditionally, most car accidents have come from the aging or overuse of batteries, and IBS is an important module in modern energy management. On the one hand, it can intelligently use battery capacity to save fuel, on the other hand, it can Always maintain vehicle availability.

If the battery is fully charged, the electronic device will interrupt the power transfer from the generator to the battery, thereby reducing the amount of energy the engine provides to the generator. Significantly reduce CO2 emissions and ensure more mileage when driving the same way.
