E-Cooler BTM / BCS

E-Cooler

The fast growing electrification of mobility – particularly in public transport – requires high-performance mobile energy storage systems that enhance travel comfort.
With E-Cooler Spheros has introduced a range of battery temperature management models with a maximum cooling capacity of 10 kW, offering an optimal solution for a wide range of applications. Depending on the requirement, the E-Cooler protects the battery from overheating during charging and discharging, cools it while driving at higher outside temperatures and heavy loads.
An additional heating function even warms up the sensitive batteries if necessary to ensure the optimal temperature range for the charging cycle.

Highlights

BCS : Standalone solution with active or passive cooling circuit in the basic version

  • Integrated control unit with intelligent working algorithm
  • Integrated water sensor for controlling the unit to reach and keep the desired water outlet temperature
  • CAN-bus connection to the vehicle
  • 24 V fan, 600 V EDC
  • Modular design enables individual adaptation in terms of performance, switch-off temperature

BTM : Active / Passive cooling circuit, water circuit, water pump, electrical heater and expansion tank.

  • Integrated control unit with intelligent working algorithm
  • Integrated water sensor for controlling the unit to reach and keep the desired water outlet temperature
  • CAN-bus connection to the vehicle
  • 24 V fan, 600V EDC
  • Modular design enables individual adaptation in terms of performance, switch-off temperature

Low life-cycle-costs

  • Energy-optimized operation of the BTMS extends range of the bus
  • -> Control of compressor and fan according to the required minimum demand
  • -> Device always starts with passive cooling to save energy and is automatically switched to active cooling or heating mode if required
  • Strong passive cooling performance
  • -> 10kW at dT of 15K
  • -> 3KW at dT of 5K
  • The extended use of passive cooling will increase the service life of the EDC
  • Pure 24 V technology at E-Cooler 50 version: easy service

Safety

  • Safe operation of the battery is guaranteed within a narrowly defined temperature range
  • -> The way the battery is conditioned therefore has an effect on the vehicle's range
