E-Cooler BTM

E-Cooler

The rapidly growing electrification of mobility – particularly in public transport – calls for powerful mobile energy storage systems that facilitate travel comfort.

It is easily forgotten that these battery packs themselves are temperature-sensitive units: depending on the load or climatic region they have an aversion to excessive cold or heat.

This has prompted Valeo to supplement its 5 kW E-Cooler with new concepts with 8 kW and 10 kW.

Highlights

Standalone solution with complete coolant and electric heating circuit, as well as water circulating components

  • Complete coolant and water circuit
  • Modular deployment, high flexibility depending on vehicle geometry
  • Integrated controls
  • CAN-bus connection to the vehicle

Low life-cycle-costs

  • Energy-optimised operation
  • - demand-based PWM control of compressor and fan
  • - automatic switching between passive cooling and active coolant circuit
  • Pure 24 V technology at 5kW version: easy service

Safety

  • The functioning of the battery is only guaranteed within a narrow temperature frame
  • ––> battery cooling thus has an impact on the range of the vehicle

Low life-cycle costs

  • Energy-optimised operation
  • - Demand-driven PWM control of compressor and blower
  • - Automatic switching between passive cooling (water only) and active compressor operation
  • Pure 24 V technology: simple service and maintenance

Comfort

  • Standalone solution
  • High degree of flexibility depending on vehicle geometry
  • Integral control
  • CAN-bus connection to the vehicle

Reach

  • Function of battery can be ensured only in a close temperature range
  • ––> The reach of the vehicle depends from the battery cooling
