A practical guide to reviewing coolant, pump, battery, software and installation changes in an electric bus battery thermal management system.
Noch bevor der erste Fahrgast zusteigen konnte, hatte der Winter bereits die Schwachstellen der Busflotte offenbart. Wenn die Batterie eines Busses beim Verlassen des Busdepots eine niedrige Temperatur aufweist, muss das Fahrzeug zu Beginn der Fahrt den Preis für diesen…
Suppose the vehicle interface voltage in your project can reach 820 V. You then receive a quotation for a 12 kW unit. Its cooling capacity appears more than adequate, and the price is reasonably fair. However, upon checking the voltage…
With the outside temperature at 12 degrees Celsius, the cabin is already comfortable enough, yet the heater is still running at full power—this complaint does not stem from the coldest week of winter, but rather from feedback received from the…
During vehicle testing, it is truly dreadful to encounter a cold morning only to find that the heater will not start. The vehicle’s control unit sends a command to heat the system, yet the coolant remains ice-cold. In such situations,…
‘Can’t we just use that green liquid?’ We hear this question all the time—perhaps more often than you might imagine. It is usually asked by someone looking at a coolant specification sheet for the first time, whilst busy checking the…
Review power budgets, control coordination and coolant routing when considering multiple high-voltage coolant heaters for electric buses and trucks.
Review battery cold-plate requirements, coolant conditions and supplier responsibilities before selecting a BTMS.
Review low-voltage supply, control power and vehicle operating modes when integrating a high-voltage coolant heater. Confirm interfaces before sample approval.
Compare battery cooling system quotations for electric buses and trucks. Check included hardware, coolant interfaces and control responsibilities before approval.
