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 a new 10 kW concept.

Highlights

Standalone solution with active cooling circuit in the basic version.

  • Modular deployment, high flexibility depending on vehicle geometry
  • Integrated controls
  • CAN-bus connection to the vehicle

Low life-cycle-costs

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

Safety

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

Optional

  • Passive cooling circuit, water circuit and electrical heater.
