At Idneo we have professionals specialized in all areas, from industrial design to BMS development.

Our innovation team has taken a step forward by creating a swappable battery for motorcycles and Light EV.

 

Centralized BMS for 18 Cells

INTRODUCTION

Idneo’s Eco Battery is a high accuracy centralized BMS system that can manage the control of a maximum of 18 battery cells of different chemistries and all the components surrounding it, including shunt reading, main and precharge contactor control, pyro-switch among others.
The safety level of the BMS is ASIL-C rated with same actuation mechanism of the contactors and Pyro-switches.
Open API interface to include custom battery SOC, SOH or SOP algorithms.

APPLICATIONS - e-Mobility

  • LEV (light electric vehicle up to L7 quadricycle)
  • Swapable battery
  • Advanced stationary battery

KEY FEATURES

Open BMS Concept:

  • Open interface for SoX custom development
  • Configurable main App to adapt it to the needs
  • Data available after integrity checks

Acquisition with Safety:

  • Acquisition data received with ASIL-C rated components and communication
  • Safety redundant check for all sensors (Voltage, Current and temperatures)
  • Deterministic and real-time management of data and tasks

Advanced Peripheral control:

  • Contactor control with safe actuation and sensing
  • Integrity of the contactor Coil check before activation
  • Complete activation of the contactors verification

Connectivity:

  • CAN 2.0 interface
  • Interlock master based on PWM
  • Heater Control based on PWM
  • UART service connectivity
  • Neopixel output for HMI
