Cal­i­for­nia dream­ing of no diesel

The Witness - Wheels - - MOTORING - ALWYN VILJOEN

CHI­NESE all-elec­tric bus and truck builder BYD will re­ceive $9 mil­lion from a group of lo­cal gov­ern­ments who are in­vest­ing in 27 elec­tric trucks to re­place diesel-pow­ered heavy-duty tractors used in rail yards and largescale freight dis­tri­bu­tion cen­tres.

The grant is part of a larger statewide in­vest­ment in low-car­bon trans­porta­tion projects that are piv­otal to meet­ing Cal­i­for­nia’s am­bi­tious goals to re­duce green­house gas emis­sions, im­prove air qual­ity and re­duce pe­tro­leum de­pen­dency by ac­cel­er­at­ing the de­vel­op­ment and de­ploy­ment of ad­vanced ve­hi­cle tech­nolo­gies.

As the self-pro­claimed “Of­fi­cial Spon­sor of Mother Na­ture”, with a proven track record of thou­sands of ve­hi­cles al­ready oper­at­ing around the world, BYD is the ideal part­ner to help North Amer­ica’s cities de­liver on the aim to re­place ex­ist­ing diesel trucks.

BYD will test its truck for a two-year pe­riod, us­ing 23 bat­tery-elec­tric “yard goats”, trucks that are used to move heavy freight con­tain­ers short dis­tances within freight yards, ware­houses, dis­tri­bu­tion cen­tres and port ter­mi­nals; and four medium-duty trucks at two of its in­ter­modal rail yards in the cities of San Bernardino and Com­merce.

Both truck types will be de­signed and man­u­fac­tured by BYD in Lan­caster, Cal­i­for­nia.

Apart from shunt­ing yards, BYD is also de­vel­op­ing trucks for a range of vo­ca­tional mar­kets, in­clud­ing refuse trucks, drayage trucks, con­crete mix­ers and yard trucks, which will sig­nif­i­cantly re­duce emis­sions and im­prove pub­lic health.

“BYD’s class eight heavy-duty yard truck and class five medi­um­duty ser­vice truck tech­nol­ogy will prove that ve­hi­cle elec­tri­fi­ca­tion is a so­lu­tion that can be ap­plied to­day to a va­ri­ety of needs — not just pas­sen­ger ve­hi­cles,” said Stella Li, pres­i­dent of BYD Mo­tors.

“BYD is proud to col­lab­o­rate on this project and show­case our best-in-mar­ket elec­tric bat­tery tech­nol­ogy. By de­ploy­ing these trucks in 24/7 oper­a­tions, this project will prove that truck elec­tri­fi­ca­tion can be adopted at any ma­jor freight lo­ca­tion and scaled for any fa­cil­ity and busi­ness need in the U.S.”

While most car mak­ers use lithium, nickel, man­ganese, cobalt, ox­ide (NMC) type bat­ter­ies for their high-en­ergy den­sity de­spite its in­sta­bil­ity, BYD uses lithium, iron, phos­phate bat­ter­ies in its ve­hi­cles.

The range is roughly half, but these bat­ter­ies are very sta­ble. Know­ing the large bank of bat­ter­ies un­der the bus floor will not get hot and start fires is more im­por­tant than range.

BYD said its lithium, iron, phos­phate bat­tery of­fers three ad­van­tages on com­pet­ing tech­nolo­gies: • it lasts longer, keep­ing 70% charge after 10 000 cy­cles, com­pared to other lithium ion bat­ter­ies that rapidly de­grade after 2 000 cy­cles or five or six years of reg­u­lar use; • they are ex­tremely safe as the chem­i­cal re­ac­tion is not exother­mic (no heat is re­leased) and no oxy­gen is re­leased; and • they are en­vi­ron­men­tally friendly as the pri­mary com­po­nents are iron, which is the most com­mon el­e­ment on Earth by mass, and phos­phate, which is nat­u­rally oc­cur­ring.


The BYD T9 all-elec­tric medium hauler truck will soon go on test in Cal­i­for­nia, where lo­cal gov­ern­ments want clear skies with no diesel fumes.
